This is called though cocoa.h and foundation.h, then NSURLError.h. Not sure why this compiler error just came up when I added portaudio and some other needed frameworks. The error first comes from some existing code. Indeed, there is no CoreServices/CoreServices.h anywhere on the whole system. Do I need to update Xcode?
I found an Apple help answer that said "Those are not makefile directives. How are you trying to build it? Most projects like this come with "configure" scripts that you just need to run from the command line. The only thing you need from Xcode are the Command Line Tools." I don't know what this means or how to do this.
I did run the port audio/configure terminal script, but saw nothing about CoreServices.h being generated. Where does this need to come from?
Thanks.
I further note that in the CoreServices frameworks directory associated with the Xcode project, there is a terminal file called "CoreServices" that when run, generates the error "CoreServices.framework/Versions/A/CoreServices: cannot execute binary file" . What could it be missing?
It's hard to answer your question in this specific case but:
I believe that CoreServices.h can be found at /System/Library/Frameworks/CoreServices.framework/Versions/A/Headers/CoreServices.h, is it not the case on your machine? If not, you might have to re-install Xcode
To install PortAudio, you can also use brew with the command brew install portaudio and then link your project with its headers and libs (/usr/local/Cellar/portaudio/19.6.0/include and /usr/local/Cellar/portaudio/19.6.0/lib) in your Xcode project (under the tab Build Phases > Link Binary with Libraries). That might be the easiest option.

I'm trying to build emacs-25.1 from source on OSx. Everything goes fine until make install. When Emacs is trying to compile xml.c I get:
xml.c:23:10: fatal error: 'libxml/tree.h' file not found
#include <libxml/tree.h>
What is happening?
I'm not sure what your exact error is. However, there is an easier way to build emacs25 on OSX and macOS. Install homebrew is easy and once you have it, all you need to do is run
brew install emacs --with-cocoa --with-rsvg --with-ns
and then
brew linkapps emacs
and your done. Even if you want to do it by hand, you can get the recipe homebrew users to see how it does the build and install, which might help track down your error.
NOTE Check what the actual args are you can pass to the build environment. the ones I've listed are from memory and there are some others you may want to include.
A colleague was having the same problem and posted in the GNU emacs devel list right here. Daniel Suton provided the answer. Xcode is missing:
xcode-select --install
MacOS provides a libxml implementation (and headers) by default when you install xcode. Note that I had installed xcode already. But I've also upgraded from EL Captain to Sierra so my xcode installation must have been erased in the process.
Anyway, after installing xcode like described above and then after git clean -fxd I was able to rebuild emacs again.
For the past week, i have been hunting a free development environment for STM32F1xx, which is supported by FreeRTOS. And no success yet :( .
Now I've found this: http://www.stf12.org/developers/ODeV.html
It's an Eclipse configuration for STM32 compiling and debugging, and there is a FreeRTOS demo too. Perfect!
So I downloaded a preconfigered version of eclipse and tried to compile a demo project to get this error:
Cannot run program "cs-make": Launching failed.
Depressing. Please help, i am very bad at configuring IDE's, compilers and linkers so this has to be newbie-friendly :)
The Eclipse project is configured for CodeSourcery toolchain. You need to install CodeSourcery compiler toolchain from: http://www.mentor.com/embedded-software/codesourcery. Choose Lite Edition, ARM-NONE-EABI package. After the installation make sure you can start cs-make from command prompt (by typing it's name there). Generally, you want all toolchain programs to be accessible from command prompt, which implies that their installation path must be in system PATH variable.
P.S.
Make sure the path DOES NOT contain spaces like standard Windows programs directory "C:\Program Files", instead install the tools in a directory like "C:\arm-none-eabi", "C:\ARM_tools" or something like that.
Ah, thank you got it to work now!
And I ran into another problem too. When I tried to compile another error came up saying something like: "C:\Program is no file or directory". I Solved it by placing all compilers and OpenOCD in the root of my C-drive. I think it's because the make doesn't understand spaces in the make file, if anyone else get the same problem.
I'm new with XCode and still trying to understand objective-C. I'm using xcode 4.3.2, and I have to create an app that integrates with PJSIP.
I found this link. I am still confused about that link, because the article said that we must have installed the command line tool. But the command line tool is already installed in my XCode. How can i use it?
Do I need to create a view base application? how can I run the command line tool like the link says?
The command line tools allow you to compile "traditional UNIX programs" from source, generally using make. If you are using Xcode to create your projects then you don't even need them installed.
EDIT OK you have edited your question, stating the real issue you are facing; You don't know how to use the PJSIP package you have installed. The link you reference is about building PJSIP, not using it, so you can still forget about the command line and concentrate on how to configure your Xcode project to use PJSIP. This will require setting the header search paths and library search paths to find the header files and library file, in order to compile and link against it. Hopefully it's a static library as that will be easier to use; if it's a dynamic library or framework then you have your work cut-out as that's much harder to use.
In newer XCode (4.3 or above) you might have to install command line tools since it has been made optional. Open XCode and go to XCode->Preferences
Open the Downloads panel and click on "Components". If Command Line Tools are not installed already, you will get an option to install them from here.
Do so and you are set.
I done with it by myself. if you face the same problem, you can refer to this link, I already tried and run it. It works both on simulator and device. thanks.
I'm using NetBeans 7.1 on Windows 7. I downloaded the CUnit archive and used shell scripts supplied with the archive to install it ($make install, etc.). I'm using Cygwin as my compiler, and whenever I try to build the unit test, I get the following error:
/usr/lib/gcc/i686-pc-cygwin/4.3.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lcunit
Obviously, the linker (ld) doesn't know where to look for something, but I don't know the intricacies of how this stuff works. Searching for lcunit on my computer didn't return anything except for the makefile of this project.
One thing I think I should mention is that when I installed CUnit, NetBeans did not know where to look for it. It got installed into /usr/local/ and this was not one of the paths NetBeans parsed.
"-lcunit" is just a flag/option instructing your compiler to link all cunit stuff in your app.
usage could be something like this (gcc):
gcc test.c -lcunit -o test
looks like your compiler doesn't know what to do with this flag... :/
I'd like to use clang on my Xcode iPhone project. However this is the getting started guide:
http://clang.llvm.org/get_started.html
I've been working with Xcode for a year but this is far far far from being understandable to me! Can anyone explain in plain english how to install and use Clang with my existing iPhone project? I am not familiar with loading things from the console.
Thanks!

Nikita Zhuk has wrapped Clang in a GUI and made it available at http://www.karppinen.fi/analysistool/. Very useful.
Download and extract the clang distribution to some directory. Optionally add this directory to your path, or you can just prepend it's location to the command line later on.
cd to your top level project directory (probably something like cd ~/Documents/yourprojectdirectory)
Tell the clang utility to do a build of your project using your xcode project settings by typing in the following command line: pathtoclangdirectory/scan-build -o ./clang_out xcodebuild
The utilty should give you a message after it has run successfully to run the scan_view utility.
Run the command that was output at the end of the build. This will start a temporary web server on your machine and then open up Safari and show you the code analysis. You may need to prepend the path to your clang directory again, like so: pathtoclangdirectory/scan_view ...
I didn't see this question until after I had done something similar to make Clang more useful inside XCode:
Using Clang Static Analyzer from within XCode
