So I've boned my system. I'm running LFS with xfce and it has been running perfectly. I needed to install a video editing package and some dependencies (AppStream, stemmer) but they failed during the install. At the time I didn't think much about it and decided to come back to it later. Now when I run the configure, it get a message:
error: C compiler cannot create executables
I decided to create a test file that just outputs "Yo Dude!" in the terminal. When I try to compile it I get the message:
error: no include path in which to search for stdc-predef.h
It seems as if it can't find the library files, even putting the absolute path to stdio.h doesn't work. I did notice that gcc now shows as 11.2.0 but when I installed the system, I installed 12.2.0. I downloaded 12.2.0 but it won't compile. I can't compile because gcc is broke and I can't install gcc because gcc is broke. I'm trying not to re-install the system. Any suggestions on how I can get around this?
I can't find any documentation whatsoever on how to target 32-bit with Red Hat Developer Toolset (version 9.0 in this case running on CentOS 7). The release notes mention:
Generation and manipulation of 32-bit binaries is also supported
It also ships the needed 32-bit libraries in:
/opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/32/
However, building fails. Example trying to build a minimal int main() {} program:
$ scl enable devtoolset-9 'g++ -m32 tst.cpp'
/opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: skipping incompatible /opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/libstdc++_nonshared.a when searching for -lstdc++_nonshared
/opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: cannot find -lstdc++_nonshared
collect2: error: ld returned 1 exit status
The library it fails to find actually exists though:
/opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/32/libstdc++_nonshared.a
No amount of -L flags fixes it (and it would be the wrong solution anyway; the linker should not even be attempting to load 64-bit libraries in -m32 mode.)
What am I missing here?
I guess you didn't notice that /opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/32/libstdc++_nonshared.a is quite likely a dangling symlink:
$ file /opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/32/libstdc++_nonshared.a
/opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/32/libstdc++_nonshared.a: broken symbolic link to `../../../i686-redhat-linux/9/libstdc++_nonshared.a'
$
The destination file /opt/rh/devtoolset-9/root/usr/lib/gcc/i686-redhat-linux/9/libstdc++_nonshared.a is however unfortunately not provided by any CentOS package (but it should be in devtoolset-9-libstdc++-devel.i686). Thus it's likely a CentOS-specific packaging mistake as RHEA-2019:4134 provides the questioned package devtoolset-9-libstdc++-devel-9.1.1-2.6.el7.i686.rpm for Red Hat Enterprise Linux 7 including the desired file (explicitly verified by yum install /opt/rh/devtoolset-9/root/usr/lib/gcc/i686-redhat-linux/9/libstdc++_nonshared.a on RHEL 7).
I've a problem to install the aforementioned module via cpanm in my multi-threading version of Perl (not the original one).
I've Ubuntu 16.04.
When trying to compile and test this module it gives me the following error:
/usr/bin/ld: impossible to find -lz
collect2: error: ld returned 1 exit status
Makefile:494: instructions set for target "blib/arch/auto/Net/SSLeay/SSLeay.so" fail
make: *** [blib/arch/auto/Net/SSLeay/SSLeay.so] Error 1
-> FAIL Installing Net::SSLeay::Handle failed. See /home/my_name/.cpanm/work/1548275319.13675/build.log for details. Retry with --force to force install it.
openssl,ssllib-dev-perl,libnet-ssleay-perl, libcrypt-ssleay-perl already installed via apt-get.
I've also tried to compile manually this module, without success. I forced the installation too...no way.
The error seems linked with something missing in /usr/bin/ld: (impossible to find -lz collect2).
Is there anyone who can help me with this?
Cpanm has always worked pretty well. Up to now i've been able to get all my modules installed and well functioning, apart from Net::SSLeay::Handle.
Thanks in advace for your help
Ok, i solved by installing this packages (Ubuntu 16.04LTS):
-openssl
-libssl-dev
-libnet-ssleay-perl
-libcrypt-ssleay-perl
-zlib1g-dev as suggested above
Once you're done doing that, remember to avoid testing the module when gcc will be finishing compiling it, because in most cases it fails.
So the best incantation in doing this should be as follows:
-cpanm install -v --notest Net::SSLeay::Handle
Many thanks again to all Perl mates writing in this forum.
You saved the day
first log in cpan
sudo cpan
force intalling the module should work
force install Net::SSLeay::Handle
This should also install missing modules or notice it
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: bash-4.4.019-2 is up to date -- skipping
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.
I can not run GNAT Programming Studio on Raspberry PI 3 (Raspbian).
I am using 2017-06-21-raspbian-jessie.img and gnat-gpl-2016-raspberrypi-linux-linux-bin.tar.gz
After unzipping and typing in terminal sudo ./doinstall it is installed in /usr/gnat. Then I get a message saying
GNAT GPL is now installed. To luanch it, you must put /usr/gnat/bin in front of your PATH enviroment variable.
Then I type in terminal PATH="/usr/gnat/bin:$PATH"; export PATH.
Then I type in terminal gps after that I get
/usr/gnat/bin/gps_exe: 1: /usr/gnat/bin/gps_exe: Syntax error: word unexpected (expecting ")")
I have tried executing executable in /usr/gnat/bin but then I get
/usr/gnat/bin/gps_exe: cannot execute binary file: Exec format error
How to install it properly and be able to run it?
You need to install it on an x86 computer.
From the README:
The GNAT GPL compiler for raspberrypi is a cross compiler, hosted on
linux-x86 (or linux-x86_64)
