Problems compiling using GCC in execvp

Subject: Problems compiling using GCC in execvp

Hi,

I'm having some issues when trying to compile some files when using execvp to launch GCC.

I'm basically forking, then calling

execvp (bin, argv);

Where bin is a char* to "gcc" and argv is a pointer to the array of char* below:

-fPIC
-o
/tmp/simpl-so/objs/783b8f28.o
-I
/simpl/dev/src
-I
/simpl/dev/src/core
-I
/simpl/dev/src/include
-c
/t/bufout.c

I am getting the following output from the compiler:

There are a few issues here, the most important for me to fix is the definition of size_t. AFAIK this is normally done in stddef.h, however on my system, there's no /usr/include/stddef.h and the one under /usr/include/linux/stddef.h only defines NULL, and I'm not quite sure where else it might be defined.

Also, when I run GCC from the shell, everything compiles without errors. I'm wondering what other information I need to add to my options to prevent the errors. I've tried adding /usr/include/linux as an include path, but that only solves the initial problem of finding a stddef.h file, and then causes other errors to appear.

Note, this problem only seems to be on my 64-bit Ubuntu version 9.04. The 32-bit version worked on my old computer before I transfered the data to my new one, but I can no-longer test it on the 32-bit machine.

I'd be grateful for any pointers that might help me sort this one out.

Thanks,

Marcus.
