Objective-C compiler not installed on this system

When I try to compile code from the command line
(gcc -framework Foundation Prog1.m -o Prog1),
I receive the message that states Objective-c compiler is not installed. I installed the XCode from the Mac OS X cd, and upgraded to XCode 4.0.2.

I figure there is not a PATH set properly. Anyone have a clue?

Installing the development tools (Xcode) will install GCC, the appropriate libraries and will create symlinks where necessary. Execute the following to see what it returns (it should return /usr/bin/gcc): If that returns nothing, try reinstalling Xcode. Someone else here had an issue recently similar to yours and reinstalling fixed it.

When I enter "whereis gcc", it returns /usr/bin/gcc.

You should have all the appropriate tools. I just did it here with a simple hello world app and it worked perfectly fine (I'm using GCC 4.2.1). Have you tried reinstalling the dev tools? Have you tried compiling this through Xcode? Others have noted that compiling through Xcode works when it doesn't work doing it "manually" (by hand at the CLI).

Could be. If you did the install, and haven't logged out since then, that may be the trick. That PATH gets setup during login. Yes, you can set it manually.

Still no luck

I reinstalled X Code 4.0.2. I can create a simple "Hello World" through X Code and it works. If I try to compile with a GCC command, I still get the message "Objective-C not installed. I have rebooted.

is /Developer/usr/bin/ in your path?

Yup. Result of echo $PATH = /usr/local/gnat/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/X11/bin

Anybody have a path for a system that works?

well, here's mine. I don't see it as being hugely different.

I've installed both 3.2 and 4.x of Xcode. Here is my path when in the tcsh and the whereis statement result for cc.


[mac:~] xstep% echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/mysql/bin

[mac:~] xstep% whereis cc
/usr/bin/cc

Thanks

Thanks to all who helped. The problem was in my path. Even though "whereis gcc" returned the correct gcc, "which gcc" follows the path and pointed to the gnat gcc. Once I corrected the path, it worked properly.

My "whereis gcc" shows the correct path where as "which gcc" does not. Please suggest how could I fix it

whereis will search a preset list of directories and which will only search your PATH. If whereis finds it and which doesn't, it sounds like the issue is simply that gcc is not located in your PATH. See here for more info.
