Setting up GTK+ on Mac - gtk

I'm trying to set up GTK on Mac but keep getting errors while compiling my code. I'm new to Mac so don't have a lot of knowledge. I installed GTK using homebrew. The current version installed is GTK 2.24.28_2. While compiling the program I get the following errors:
clang: error: no such file or directory: 'pkg-config --cflags gtk+2.24.28_2'
clang: error: no such file or directory: 'pkg-config --libs gtk+2.24.28_2'

Wrong quote types. You want backticks, `, which are to the left of the 1 key. You're using straight quotes, ', which are to the left of the Return key.
In addition, the name of the package that you give to pkg-config is just gtk+-2.0; the rest of the version number doesn't go there.
Technical explanation: the shell takes anything between `...`, runs it as a command, and inserts the output of that command back into the command line. The shell takes everything between '...' and places it as a single string unprocessed in the command line. So you're not running pkg-config at all; instead, you're passing the whole pkg-config invocation as an argument, which is not what you want. pkg-config's job is to print the flags that gcc/clang need to find a package, so you use `...` to run pkg-config and copy those flags back into your gcc/clang command line instead.

Cannot run 'make' in VScode Terminal

For a school assignment, I am trying to compile a C file using a provided Makefile in Vscode. The makefile contains the following:
CFLAGS += -std=gnu11 -g
EXES = greet
all: $(EXES)
clean:
rm -f $(EXES)
greet: greet.c
# don't treat all and clean as file targets
.PHONY: all clean
When I run make in the VScode terminal, it gives me:
bash: make: command not found
Why is this happening? The assignment says this:
The accompanying Makefile will build the program greet. Thus, you can compile the
program by running make. The make program will print out each command that it uses to
compile the program. Note that if you run make twice in a row, the second time it won’t do
anything, because it knows your source file hasn’t changed.
Run the program using the following command:
./greet
I don't know if this has anything to do with my tasks.json file in VScode?
I also ran across this VSCode extension: https://naereen.github.io/Makefiles-support-for-VSCode/
It says Vscode now has something built-in: https://github.com/microsoft/vscode/tree/master/extensions/make
I don't know how to install this.

C program does not run on buildroot

I work for buildroot. My purpose work GUI on my buildroot with Gtk3.0 and Gstreamer1.0. I use Olinuxino A13 so I wrote GUI code(Gtk3.0 hello world example) on this with codeblocks. I use Debian wheezy. I want transfer this code from Debian wheezy to buildroot.
I tried this:
I transferred /path_to_proectfile/bin/Debug/my_program.my_program created by codeblocks. I wrote ./my_program on terminal and code work. I transferred this file to my buildroot but ./my_program does not work. It returns No such file or directory error.
I thought the problem might be compiling and tried compiled on terminal. I use gcc -o my_program main.c 'pkg-config --cflags --libs gtk+-3.0' again work on Debian wheezy terminal. After I transferred to buildroot but result does not change. I tried different compile kind like cc,arm-linux-gnueabi-gcc etc. but every time No such file or directory error.
Finally when I don't use gtk library(Just use printf Hello World), I saw Hello world. When I add gtk library returns No such file or directory error. Have you any suggestion?
You need to cross compile your program with the corresponding buildroot toolchain. It looks like you have transferred a binary which was built against a different libc (this gives a "No such file or directory" error).
The buildroot cross compiler with the correct libc can be used by setting CC to "path_to_buildroot_output/host/bin/arm-linux-*-gcc" (the exact name depends on which toolchain options you have chosen).

Installing GTK for use in Code::Blocks on Windows 10

Original Question
I am having trouble installing gtk to start building GUIs in C++ on Code::Blocks. Could anyone nudge me in the right direction? I'm running Windows 10 (64-bit) on a Lenovo.
I attempted an installation guide (https://www.youtube.com/watch?v=jvQXvTtSIQo), stack overflow (How do you install GTK+ 3.0 on Windows?), the official GTK installation guide (https://www.gtk.org/download/windows.php), a written guide (http://www.tarnyko.net/repo/gtk3_build_system/tutorial/gtk3_tutorial.htm), and just noticed a very similar stack overflow (Install GTK for c on Windows 10?)
Before this, my PATH environment variable only recorded C:\Users\Owner\AppData\Local\Microsoft\WindowsApps;C:\Users\Owner\AppData\Roaming\npm;C:\Users\Owner\AppData\Local\atom\bin;%USERPROFILE%\AppData\Local\Microsoft\WindowsApps;
I downloaded MinGW from mingw.org. This was to the youtube link's comment that the official is more stable than the one that can be installed with Code::Blocks. I added C:\MinGW\bin to PATH.
Trying the official GTK installation site, I downloaded MSYS2 and used pacman -Syu to install core system packages and pacman -Su to then update. That's the end of that, so I think gtk is officially installed, I just need to get it to talk to Code::Blocks. I added C:\msys64\mingw64\bin to PATH but that didn't seem to work.
I tried to install the all-in-one bundle for GTK 3.6.4 at http://www.tarnyko.net/dl/gtk.htm , and extracted it to C:\gtk. I now have C:\gtk\bin in PATH. GTK should be in my path in one form or the other. I can run gtk3-demo and gtk-demo-application from CMD but not MSYS2. I'm a bit confused about that. It probably has something to do with MSYS2's specific path variable, I think? But it should search the system's PATH afterward? And I don't know how to change that specific path? Probably questions for another day.
So the similar stack overflow, youtube, and written tutorial all say to use pkg-config --cflags --libs gtk+-3.0 to check for a reasonable output to see if I have gtk correctly installed. I installed
pkg-config-lite to avoid the glib circular dependency issue that How to install pkg config in windows? describes and frankly I do not understand. I added it to C:\MinGW\bin to by in my path. Now I am able to run it, but get:
Package gtk+-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-3.0' found
I tried 3.6.4 instead of 3.0. No dice. I tried just 3. Nope. I can only find gtk3 files, and not the actual version I installed anywhere. pkg-config --cflags --libs says that I need to name a library, so I tried just gtk hopiing to get libraries containing that. Nope. The rest of the tutorials are aimed at getting Code::Blocks compiler (I think) to include gtk. I hope this is the only obstacle, and I will be able to get the rest. But, if anyone can help me through the rest, it would be appreciated.
At this point I'm out of ideas. Can someone help me?
Gratefully,
John
More Questions After Liberforce's Answer
Thank you for writing up https://www.gtk.org/download/windows.php !! I bet it helps a lot of frustrated newbies like myself. I will kindly offer more proper feedback after I get everything to work. I am stuck on compiling a C/C++ program, if you can help more. Before I get to that, I want to be very clear about the precise steps I took. The step names correspond to your written instructions.
Step 1: Install MSYS2
Alright, resetting everything...
Removed C:/gtk directory from PATH and from computer, aka all the tarnyko files.
Removed C:/MinGW directory from PATH and from computer, effectively uninstalling. I read your conversation with Simon (Unable to compile code with GTK and https://chat.stackoverflow.com/rooms/156828/discussion-between-liberforce-and-simon) about the confusion between MinGW's terminal which includes msys1.0 and MSYS2 terminal which includes MinGW. I figured this would be safer.
Thus, I only have C:\msys64 in PATH (and what I had before, irrelevant to GTK).
Uninstalled MSYS2 (via Add/Remove Programs) and reinstalled using the x86_64 from www.msys2.org. On pacman -Syu, I received error, "msys2-runtime and catgets are in conflict" and "msys2-runtime and libcatgets are in conflict." Entered y to remove both.
I keep uninstalling and reinstallling but I hit the following problem... (5/5) upgrading pacman was at 100% and the warning pops up:
warning: terminate MSYS2 without returning to shell and check for updates again
warning: for example close your terminal window instead of calling exit
The program halts here. I assume this means to close the window. I did, and clicked OK for the dialogue "Processes are running in session: Close anyway?." Window now printed "Hangup signal received" and it is no longer responding. I use task-manager to kill it.
Openning MSYS2 by the desktop application after the first pacman -Syu gave me the dialogue to choose which shell: MSYS2, Mingw-w64 32 bit, Mingw-w64 64 bit. I instead went into the filesystem and openned C:\msys64\msys2_shell.cmd for all future instances.
Ran pacman -Syu to finish installing packages. I restart MSYS2 again, and ran pacman -Su to reveal
:: Starting core system upgrade...
there is nothing to do
:: Starting full system upgrade...
there is nothing to do
pacman -Syuu showed:
:: Synchronizing package databases...
mingw32 is up to date
mingw64 is up to date
msys is up to date
The pacman -Su, pacman -Sy, and pacman -Suu likewise reveal everything okay. Closed and reopenned C:\msys64\msys2_shell.cmd
pkg-cofig just gives "bash: pkg-config: command not found." So I ran pacman -S pkg-config and got that working. update-core, though, which is mentioned in https://github.com/msys2/msys2/wiki/MSYS2-installation cannot be found, and pacman -S update-core will not work. pacman -Ss core turns up:
msys/coreutils 8.26-2 (base) [installed]
The basic file, shell and text manipulation utilities of the GNU operating
system
And other files that seem unrelated. Results of pacman -Ss core likewise seem irrelevant.
pacman --version shows:

Ran "pacman --needed -S bash pacman pacman-mirrors msys2-runtime" to reveal:

warning: pacman-5.0.1-5 is up to date -- skipping
warning: pacman-mirrors-20160112-1 is up to date -- skipping
warning: msys2-runtime-2.10.0-2 is up to date -- skipping
there is nothing to do
I exited out of all msys shells, and ran C:\msys64\autorebase.bat, although not on a 32 bit system. I believe there is a typo when it says to reopen msys2_shell.bat, which I do not have. I openned msys2_shell.cmd. I use pacman -Suu once more to reveal that everything is okay.
Step 2 -> Step 5 (optional): Install build tools
Openned C:\msys64\msys2_shell.cmd and ran "pacman -S mingw-w64-x86_64-gtk3" (GTK+3 package) and "pacman -S mingw-w64-x86_64-toolchain base-devel" (package to develop GTK+3 applications in other languages) (defaulted to all installations when prompted).
Failed to Compile a GTK+3 Application
Restarted computer. Openned C:\msys64\msys2_shell.cmd. Following https://developer.gnome.org/gtk3/stable/gtk-getting-started.html.
Put the simple window tutorial file in C:\Users\Owner\Desktop\test_code\example-0.c . When running gcc pkg-config --cflags gtk+-3.0 -o example-0 example-0.c pkg-config --libs gtk+-3.0 , got the error in my original question. Used "pacman -Ss gtk3" to see two packages I think I need. Ran "pacman -S mingw-w64-x86_64-gtk3 mingw-w64-x86_64-gtkmm3" .
To answer your questions to Simon about this same error at Unable to compile code with GTK , pkg-config --list-all | grep gtk returns nothing, even after closing and reopenning C:\msys64\msys2_shell.cmd. "which gcc" returns:
which: no gcc
in(/usr/local/bin:/usr/bin:/bin:/opt/bin:/c/Windows/System32:
/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:
/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl)
I see gtk-3.0 under C:\msys64\mingw64\include. I have no idea how to add this to the path. "echo $PKG_CONFIG_PATH" returns:
/usr/lib/pkgconfig:/usr/share/pkgconfig:/lib/pkgconfig
Correctly Compiled a File in Console with GTK+3
Checked that GTK was in Console
I needed to open up MSYS2 in a Mingw-w64 64 bit shell. This can be preformed via the Desktop app for MSYS2 which prompts you which one of three shells you want to open: MSYS2, Mingw32, and Mingw64. Specifically, me installing gtk with the command mingw-w64-x86_64-toolchain means it can only be accessed this way.
Commands in this shell show that I do, in fact, have gtk:
$ pkg-config --modversion gtk+-3.0 --> 3.22.29
$ which gcc --> /mingw64/bin/gcc
Compiled Sample Code from Mingw64 Console
I referenced https://github.com/msys2/msys2/wiki/MSYS2-introduction to learn the file system / drive mounting syntax. I will place the sample code gotten from https://developer.gnome.org/gtk3/stable/gtk-getting-started.html in `/c/Users/Owner/Desktop/test_code/example-0.c'. I just used my favorite IDE, Atom, but any text editor would do.
Openned MSYS2's Mingw64 shell, cd /c/Users/Owner/Desktop/test_code/ , compiled with gcc \pkg-config --cflags gtk+-3.0` -o example-0 example-0.c `pkg-config --libs gtk+-3.0`` , and execute with ./example-0
Unsuccessful to Link GTK+3 and the Code::Blocks Compiler
I Understand some Linker Settings
I went into Code::Blocks. Went to Settings > Compiler... Made sure to use the dropdown box under Selected compiler to select GNU GCC Compiler, and clicked Reset Defaults because of complications when I first installed Code::Blocks. The check boxes under Compiler Flags should all blank after the reset, and so I checked "Have g++ follow the C++14 ISO C++ language standard [-std=c++14]" under General and "Enable all common compiler warnings (overrides many other settings) [-Wall]" under Warnings.
Next to where it says Compiler Flags, I went to Linker settings and added text to Other linker options. I got this text by running pkg-config --cflags gtk+-3.0:
-mms-bitfields -pthread -mms-bitfields -IC:/msys64/mingw64/include/gtk-3.0 -IC:/msys64/mingw64/include/cairo -IC:/msys64/mingw64/include -IC:/msys64/mingw64/include/pango-1.0 -IC:/msys64/mingw64/include/fribidi -IC:/msys64/mingw64/include/atk-1.0 -IC:/msys64/mingw64/include/cairo -IC:/msys64/mingw64/include/pixman-1 -IC:/msys64/mingw64/include -IC:/msys64/mingw64/include/freetype2 -IC:/msys64/mingw64/include -IC:/msys64/mingw64/include/harfbuzz -IC:/msys64/mingw64/include/libpng16 -IC:/msys64/mingw64/include/gdk-pixbuf-2.0 -IC:/msys64/mingw64/include/libpng16 -IC:/msys64/mingw64/include -IC:/msys64/mingw64/include/glib-2.0 -IC:/msys64/mingw64/lib/glib-2.0/include -IC:/msys64/mingw64/include -LC:/msys64/mingw64/lib -lgtk-3 -lgdk-3 -lgdi32 -limm32 -lshell32 -lole32 -Wl,-luuid -lwinmm -ldwmapi -lsetupapi -lcfgmgr32 -lz -lpangowin32-1.0 -lpangocairo-1.0 -lpango-1.0 -lfribidi -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0 -lintl
Explanation: When compiling from console, I used a command that included the text /pkg-config --cflags gtk+-3.0`` . The backticks mean to run pkg-config --cflags gtk+-3.0 BEFORE the higher-level compilation command, and insert whatever text comes out into the higher-level compilation command. Code::Blocks needs that text under the Linker settings.
I do not Understand the Search Directories
In Settings > Compiler... , beside where it says Compiler Settings, I clicked Search directories. I know you need to do some work here. After this, you go back to Linker Settings to finish, and your Code::Blocks will be ready to go!
If anyone can help me here, or if I figure it out, I would love to finish, in case this helps posterity. I have GTK compiling, and that is good enough for now.
Ok, let's start from the beginning.
Don't use tarnyko packages, they're outdated and not maintained anymore
Official way to get GTK+ 3 on Windows is through MSYS2
Don't blindly follow every guide you find on the internet, mixing them all together and expect things to work. Things change, and something that was advertised at some point can be outdated and plain wrong at the time you read it. If you cook a dish with 3 different recipes at the same time, don't expect it to taste good.
So:
Remove all remnants of the tarnyko bundle
Remove pkg-config-lite. pkg-config is already installed through MSYS2 if you follow official installations
Try to get things working with the MSYS2 guide (pkg-config detection, and compiling a simple GTK+ program) without the Code::Blocks integration first
Once this works, making it work on Code::Block should be a matter of setting some environment variables and pointing to the right pkg-config.
I used gtk+ bundle_2.24.10 32 bit on Windows 7.
I downloaded it from tarnkos, there's no need to do change a single setting in code blocks 17.12.

/bin/sh: mpic++ command not found in Eclipse for Parallel Application Developers

I'm trying to use Eclipse for Parallel Application Developers to do some MPI stuff but I can't get the program to compile. Below is the error I'm getting in the console:
Description Resource Path Location Type
/bin/sh: mpic++: command not found prog C/C++ Problem
I use mpic++ from the command line (bash shell) to successfully compile programs. When I run the command using bourne shell I get an error.
/bin/sh mpic++
/usr/local/bin/mpic++: /usr/local/bin/mpic++: cannot execute binary file
When I use sudo I still get the same error. But when I first change to the bourne shell then run the mpic++ command it works.
/bin/sh
sh-3.2$ mpic++
clang: error: no input files
I've been looking at ways to change the shell used by eclipse so I can use the bash shell because I can call mpic++ without any problems. I've also tried launching eclipse with sudo but that didn't work.
I have compiled mpi in eclipse successfully. Please follow the steps:
In terminal type:
$ which mpicxx
/usr/local/bin/mpicxx
You should get the mpicxx binary path as result. I have my mpicxx in /usr/local/bin/ directory.
In eclipse, go to project properties:
Set GCC C Compiler as: /usr/local/bin/mpicxx
Also set GCC C+ Compiler as: /usr/local/bin/mpicxx
Set MacOS X C++ Linker as: /usr/local/bin/mpicxx. Also set All options as -L/usr/local/lib

How do I set up SDL with Codeblocks on Raspbian

I have a program I wrote in windows using the SDL library that I would like to compile for Raspbian. I installed CodeBlocks on the Raspbian and followed these instructions to set up SDL: http://lazyfoo.net/tutorials/SDL/01_hello_SDL/windows/codeblocks/
I get the following error:
g++ -LC:/SDL/lib -o bin/Debug/SDL_menu obj/Debug/main.o
obj/Debug/menu.o -lmingw32 -lSDL2main -lSDL2
obj/Debug/menu.o: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
I later tried this tutorial (which actually matches the version of SDL I am using, although I used the previous tutorial to get it to work on Windows): http://lazyfoo.net/tutorials/SDL/01_hello_SDL/linux/codeblocks/index.php
And I get the error:
ld||cannot find -lSDL2|
I have very little experience with Raspbian or Linux which is probably why this is so difficult.
What can I do to get this set up?
You need to install all SDL2-dev packages.
apt-get install libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev
The include folder will probably be /usr/include/SDL2.
And by inspecting your build command, you're trying to pass Windows style path on a Unix machine, that doesn't end well for sure. Don't link with mingw32 if you're not using Mingw32 compiler, and you should only link against mingw32 on Windows as well.
