FIXED: I installed XCode 3.1.4 and it resolved the problem. It also installed gcc in /usr/bin so I no longer have to alter my $PATH.

As a long-time XCode user it has been installed on my Mac for years, and I have applied updates occasionally. Nonetheless gcc is not located at /usr/bin/gcc (which has not been an issue until now since I don't normally use the command line for compiling). It is however, located at /Developer/usr/bin/gcc. So I added /Developer/usr/bin/gcc to my path, hoping that would let me use gcc and make to build libjpeg under Leopard. (Aside: Apple's own jpeg support via "Image IO" appears to ignore the specified "quality" for jpeg compression).

However the ./configure script for libjpeg says:

configure: error: installation or configuration problem: C compiler cannot create executables.

But at least now that I altered my $PATH it recognizes that gcc is present.

I have not tried to debug the configure script, but figure I am missing something basic, or else XCode installation practices have changed. My XCode is 3.1.1, and gcc from the command line says "i686-apple-darwin9-gcc-4.0.1".

Can someone help me?

Hi,
I've been installed the powerpc-apple-darwin9-gcc-4.0.1. I'm now concerned with an error message from typing 'gcc -Version' into console:

''powerpc-apple-darwin9-gcc-4.0.1: couldn't run '/usr/bin/powerpc-apple-darwin9-gcc-ersion': No such file or directory"

This seems to be obvious, because the letter 'v' from version is missing. But where have I look at to correct this mistake ?
