GCC Where is it?

It does install into /usr/bin on 10.5. I think it might give you the option of putting it elsewhere, but by default, it goes in there if you install Xcode 3. Maybe if you installed Xcode 2.5 instead into 10.5 for some reason, it puts it elsewhere, for those who want to have both coexisting. Xcode 3 comes with the 10.5 install disk.

because I'm having the same problem. I just bought a Macbook Air with OS 10.5.2. I installed Xcode 3.0 from the installation DVD, and it definitely did NOT install gcc in /usr/bin. It went into /Developer/usr/bin. I can't copy it over or make a symbolic link. I've changed my path to find it, but many make files expect it in /usr/bin.

How do I get it in the correct directory????

For what it's worth, I've been installing Xcode tools onto macs since the first release of OS X and never had any problems until now.

What do you get from using the otool command?

zsh-% otool -L /usr/bin/gcc-4.0
/usr/bin/gcc-4.0:
 /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
 /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.0.0)

Hi, I'm chiming in on this thread because it looks like i'm running into a similar problem. I have installed xcode 3.0 that came with Panther. it's in /developer on my drive. I'm trying to install OpenVPN on my macbook.

first try with ./configure couldn't find gcc. i added /developer/usr/bin to my $PATH and that seemed to work, but now i get the "failed sanity check" which other forums tell me is because I don't have c++ installed. any idea what gives?

thanks in advance. John

I'm very new to terminal/Unix... Would someone be able to teach me how to set the location of gcc in the $PATH? I have hunted around the internet forever trying to get an example and it seems I'm having the same problem as this post was originally reporting... In most of the forums I've searched , most people suggest that gcc/g++/gmake aren't installed. I have installed X Code 3.0 and can find gcc 4.0 from the finder. In addition:

$ gcc -version
$-bash: gcc: command not found

BUT

$ /Developer/usr/bin/gcc -version
$ i686-apple-darwin9-gcc-4.0.1: no input files

I have gotten far enough to think that I can add to my path through the bashrc file. Is this correct? Forgive my ignorance... everyone has to learn someway, right? I've googled for 'sample bashrc files' to see if I could pick out any path settings but mostly have pulled up people's mile long customized files which were difficult to sort through for a newbie.

Thanks,

Assuming your shell is bash, then add the following to $HOME/.bash_profile

export PATH="$PATH:/Developer/usr/bin"

If you are csh/tcsh user, then in $HOME/.login

setenv PATH "$PATH:/Developer/usr/bin"

What happens when you say this:

which g++

By default, it gets installed like this, in /usr/bin :

zsh-% ls -1 /usr/bin/gcc* /usr/bin/g++*
/usr/bin/g++@
/usr/bin/g++-4.0*
/usr/bin/gcc@
/usr/bin/gcc-4.0*

Yeah, I just wonder if the OP's XCode was installed wrong. maybe an older version that did not get overwritten.

It might be worth reporting this to Apple as a bug, as it would break everything.

They were not there yesterday afternoon. But after I turned off the computer and re-booted, they were there this morning! And I did restart after installing Xtools.

I also got an invalid checksum on an Xcode 3.0 image that was downloaded via Camino. Switching to Safari, the same download produced a valid image!
