Assuming the file is called file.m and is located on the Desktop:
Then to run:
They key thing is to name the file with a .m extension so it's compiled as Objective-C, and to remember to link to whatever frameworks you're using via the -framework argument.
Code:
cd ~/desktop
gcc file.m -o file -framework FoundationThen to run:
Code:
./fileThey key thing is to name the file with a .m extension so it's compiled as Objective-C, and to remember to link to whatever frameworks you're using via the -framework argument.
I'm getting:
here is my code:
the file name is Untitled and it's in Home directory
Code:
-bash: gcc: command not foundhere is my code:
Code:
gcc Untitled.m -o Untitled -framework Foundationthe file name is Untitled and it's in Home directory
strange, both give me no such directory
maybe because I'm using snow leopard? how can I install GCC?

When you install Xcode, it installs gcc. You said you installed Xcode, right? What is in your /Developer directory? (i.e.: what does 'ls /Developer' say?)
Do you still have a partition with something other than Snow Leopard (e.g., Leopard)? Was XCode installed under a different version of Mac OS X (i.e., not Snow Leopard)?
ya, i had leopard (which i think there is where I installed xCode) then i updated to snow leopard and before two days I added dual booting with leopard
i get this :
btw what if i delete the old xCode and download iPhone SDK (it include xCode 3.2) (mine is 3.1)
Code:
-bash: /Volumes/Loeprad HD/Developer/usr/bin/gcc: No such file or directorybtw what if i delete the old xCode and download iPhone SDK (it include xCode 3.2) (mine is 3.1)
Judging by the screenshots you posted, it looks like you have a ton of broken symlinks? I would try invoking the actual gcc binary directly by compiling with this command...
Or if you just want to verify that method would work, ask for the version number...
If that works, then I would try uninstalling xcode completely and reinstalling it to see if it fixes those symlinks.
Code:
gcc-4.2 MyFile.m -framework FoundationOr if you just want to verify that method would work, ask for the version number...
Code:
gcc-4.2 -vIf that works, then I would try uninstalling xcode completely and reinstalling it to see if it fixes those symlinks.
