Compilation error under Unix with GCC

[marcusg]

Hi there,

I'm getting the following error when compiling a C program under Unix using the GCC compiler via a Makefile.

wvc_stream.c: In function `STREAM_Printf':
wvc_stream.c:131: `__builtin_va_alist' undeclared (first use in this function)
wvc_stream.c:131: (Each undeclared identifier is reported only once
wvc_stream.c:131: for each function it appears in.)

I did a search on google and this seems to be a frequent problem, perhaps related to an incorrect installation of GCC (notably an incorrect stdarg.h header file), but I've not been able to find a definitive solution.

Anyone have any information on this?

Thanks!

Marcus

It looks like it's not linking properly.

Thanks, have managed to resolve the problem.

It was caused by an old/incorrect version of stdarg.h in the /usr/include directory.

I copied in a newer version of this file that I found under version 3.2.3 of GCC and the program compiled fine.
