Building GDC on Ubuntu

[edam]

Hi there,

I'm trying to follow the instructions at https://bitbucket.org/goshawk/gdc/wiki/Home to build GDC from the mercurial repos, but I've not been successful. Not being familiar with the GCC build process myself, I was wondering if anyone could shed a bit of light on the problem?

I should state ahead of time that I ran ./gcc/d/setup-gcc.sh with -v2 and my system is x86_64 running Ubuntu 10.10.

It fouls up during compilation of libphobos. I get this:

gcc -g -O2 -g -Wall -I ../../../../libphobos/../include -c -o config/x3.o ../../../../libphobos/config/x3.c
In file included from ../../../../libphobos/config/x3.c:1:
/usr/include/string.h:34: fatal error: stddef.h: No such file or directory
compilation terminated.

I have tried sticking a '-v' in to that call to gcc and found this:

#include <...> search starts here:

End of search list.

Which explains why it can't find /usr/lib/gcc/x86_64-linux-gnu/4.4.5/include/stddef.h (which does exist).

Anyone know what I'm doing wrong?
