Xcode gcc exit status 1

First of all I am very new to all this.

I recently upgraded to Snow Leopard and installed the Xcode + iPhone dev package, 3.1.2. I went on to install the Django framework + MYSQLDB handler. During the build stage, the terminal shows me the gcc exit status 1 error. But I have the Xcode already installed?

Where am I going wrong?

Also while trying to fix things up, I installed the Xcode that came with the Snow Leopard DVD. still the same error.

Now I think I should remove the Xcode completely and do a fresh install?

Is the ver.3.1.2 specific to 32-bit? Please help me out.

Here is the complete error:

I am not sure if you solved your problem. I got the exact same issue after I upgraded from Mac OS 10.4 to 10.6.

Following some blog posts, on a hunch, I ran setup.py pointing to an older gcc version (gcc-4.0).

CC='/usr/bin/gcc-4.0' python setup.py build

The build encountered few warnings.

Ran the same command again.

Everything works now magically. The install also went through. The module works as expected.

It normally also shows why a compilation fails. Could you give the text preceding "gcc exited with code 1" or something like that? And perhaps the source file also.

Also look for other threads on this subject, like this one. Good search terms on google or stack overflow are leopard and MySQLdb.

If it helps any, I solved this issue with sym links, and I think it will work for you. I wrote this with my version of gcc in mind, which is 4.2:

cd /usr/bin
rm cc gcc c++ g++
ln -s gcc-4.2 cc
ln -s gcc-4.2 gcc
ln -s c++-4.2 c++
ln -s g++-4.2 g++
ln -s gcc-4.2 gcc-4.0

There ya go!
