Good morning,

i want to build gprolog on OS X using pkgsrc and it fails:

<quote>
gplc -c -C '-O3 -finline-functions -fomit-frame-pointer -D__unix__=1 - 
funsigned-char' error_supp.c

The problem might be, that i try to build this package with gcc4.  
Darwinports uses gcc3 to build this package, but i'd like to use gcc4.

I found this link [1], i applied the mentioned fixes to the work dir  
and tried to go on using bmake.

After these changes, the first error is gone but i get a new error:

<quote>
gplc -c --fast-math fd2c.pl

system_error(cannot_catch_throw(error(domain_error('',fx),op/3)))
warning: /home/diaz/GP/src/src/Pl2Wam/read_file.pl:106: system  
directive failed
fatal error: exception raised: error(domain_error 
('',prolog_name),current_prolog_flag/2)
compilation failed
</quote>

I used this patch, because i did not find something else and the  
patch is for a later version of gprolog and should solve another  
problem (get rid of another error message). In my case it helps me  
get rid of the first error message but later i get the error message,  
the patch should get rid of in the first place. Very strange.

Has anybody had similar issues or does anybody have a clue what i can  
do? I could ust gcc3, of course, but since i built all the other  
packages i have with gcc4, i would like to use gcc4 for this one, too.

Thanks,
	Philipp
