How to compile objc code on Linux?

Question

Assuming you have your .h and .m ready on a Linux server, which command would you issue to GCC to have it compiled?

Just a heads up: you cannot compile code that uses Apple's Cocoa classes. I recommend reading this post: [Starting iPhone app development in Linux?](http://stackoverflow.com/questions/276907/starting-iphone-app-development-in-linux) — Jeremy, Dec 21 '11 at 17:21

The relevant parts:

gcc -c -Wno-import List.m

gcc -o prog -Wno-import List.o main.o -lobjc

. . . make sure that the Objective-C library and header files (objc/Object.h) were installed when gcc was built.

Note that when linking Objective-C with gcc, you need to specify the Objective-C library by using the -lobjc switch.

See this link for more information.

Additional link with possible solution to the missing compiler issue:

Try installing either gobjc++ or gobjc

sudo apt-get install gobjc++

For RHEL, try the gcc-objc or gcc-objc++ package via yum. – Harold L Sep 11 '13 at 20:43 — Harold L, Sep 11 '13 at 20:43

Comes back with `gcc: error trying to exec 'cc1obj': execvp: No such file or directory` Is there some setup that needs to happen prior to this? – James Raitsev Dec 21 '11 at 17:17

Try to install "gobjc" package, this should fix the problem. – Manlio Dec 21 '11 at 17:25
