Re: can't compile GNU Prolog 1.4.1 with gcc 4.4.2?

Hi,

I'm currently not at my office and I won't be able to dig into this before a while. However, from what I can see, it seems the struct sigcontext is used (and it is not defined). I don't know fedora but I expect the more standard function sigaction is supported (so sigcontext should not be used). To confirm this, please check the output of ./configure looking for the line:

checking for a working sigaction... yes / no

If you obtain 'no' this explains why sigcontext is used and then you can try to force sigaction adding the following lines to EnginePl/stacks_sigsegv.c just BEFORE the #include "engine_pl.h"

#include "gp_config.h"
#define HAVE_WORKING_SIGACTION

Then try a:

make clean
make

If it is not better, we can try to force sigcontext to work well. Remove the (above) added lines. From memory you can try to 
#include <asm/sigcontext.h>
just AFTER #include "engine_pl.h".

then

make clean
make

Thank you for keeping me informed

Daniel
