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.

Hi,
I'm running Windows Vista Business 64 on an AMD64 box. See below my sig
for 'perl -V'.
I've built Inline::CPP on previous Cygwin installations (on Windows
2000) and on "native" Win32 builds of perl , but attempts to build this
module under Cygwin are now failing under 'make test' with the following
errors:

collect2: ld returned 1 exit status
perlld: *** system() failed to execute
-------------------------------------
My immediate thought is that the problem arises because, as is evident
from the above copy'n'paste, 'gcc' is being invoked instead of 'g++'.
Is there some %Config::Config{} key that contains an inappropriate
value, or does the bug lie within the Inline::CPP-0.25 source ?
Cheers,
Rob
