Re: Trying to build (perl) Inline::CPP-0.25.

[Paul Mallas <pmallas at rsmas dot miami dot edu>]

I ran into a similar problem recently - the standard sort of c++ 
references were not being found.  It turns out that the linker I was 
calling was ld2, a script that called another script perlld (in 
/usr/bin), where I found this:

# these are pretty mandatory
my $CC = 'gcc';
my $EXPORT_ALL = 1;

I edited this script and replaced gcc with g++. I don't know if this was 
a good idea or not, but it seemed to fix the problem.
