I have installed clang on my Raspberry Pi. How can I compile a .m file (Objective C) through the terminal?
Let's say I called it bob.m and I want the output file to be called bob and I'm already in the correct directory, what is the exact command?
To compile Object-C:
clang <the file name, i.e. bob.m> -o <the target name, i.e. bob>
so
clang bob.m -o bob
Foundation is part of GNUStep which will have to be installed.
sudo apt-get install gnustep
You will then need to tell clang about it.
clang `gnustep-config --objc-flags` bob.m -o bob `gnustep-config --base-libs`
You need to instal the objective c run time libraries as well as OpenStep/gnuStep if you want to import foundation.h. Objective-c does not come bundled with clang.
Apparently you can get gnustep with apt-get:
sudo apt-get install gnustep
Once that is installed, you should be able to compile against foundation.h
