Re^5: XS module build not working for Perl 5.8

I think you might be educating me here ... I downloaded the Perl binary for 5.8.8 from ActiveState. This is the Perl that I am running and trying to build XS based modules in. Are you telling me that I must use the same compiler as ActiveState used to generate the binary?

In general, this is true, since the module build process will try to use compilers/linkers/options determined when perl was built. I know solaris has stuff to allow building modules with gcc via Solaris-PerlGcc, and recent ActiveState Win32 perl is supposed to also allow building modules with MinGW's gcc. But I don't know about ActiveState's Solaris perl or how any of those bandaids work with C++ modules.

I'd really recommend building your own perl, perhaps starting with the Configure options given by perl -V:config_args on the perl you are using now. Also note that not many people build C++ modules, so IIRC that occasionally has been broken.

How are you building your module now? It's starting to sound to me like you have your own makefile rather than having ExtUtils::MakeMaker build one; if so, you can expect breakage whenever perl's Config changes.

I build them the usual way (I think). I run "h2xs -A -n MODULE_NAME". You have to make several edits to the files in the module to make them C++ compatible. This includes adding an XSOPT => '-C++' line to Makefile.PL. So the answer to the second question is that I am using MakeMaker, I just have to make a few changes to Makefile.PL. There is a good summary of the processs here: http://www.johnkeiser.com/perl-xs-c++.html I have tried to build my own Perl binary but I am having considerable problems. Let me run this by you and see what you think though ... in the past when this worked, I compiled using gcc. But for some unknown reason, gcc is broken at my site. So I have been using Sun's CC compiler instead. I wonder if this isn't the source of my problem?	[reply]

Ok ... the module built fine with perl 5.6. So if you take the exact same source that worked with 5.6 and try to build with perl 5.8, it fails ... right ? (There are exceptions, but you would generally expect that source code that compiles with 5.6 would also compile with 5.8.) So I have been using Sun's CC compiler instead. I wonder if this isn't the source of my problem? That could be the case (especially if 'perl -V:cc' returns "cc='gcc';"). What does 'perl -V:cc' return ? Cheers, Rob	[reply]
