This must seem easy to you because you know all this and apparently have access to multiple compilers and platforms. I believe being able to do this 99% right is very much dependent on experience. Thus it would be a very good candidate for being solved once by experts and reused by fools like myself. > Another interesting information is binary compatibility between > versions.

I guess if you replace the compiler of a system with an incompatible one, you're asking for trouble anyway. I don't see how we could possibly do anything about that. > And I'd like a way to guess the C++ compiler that was used to build a > binary (using embedded strings, linked libraries, ...). That would be nice. Another thing I'd like (even more, actually) is guessing the C++ compiler from the C compiler that was used to compiler Perl. What information I found on CPAN is mostly from Inline::CPP: http://search.cpan.org/~neilw/Inline-CPP-0.25/lib/Inline/CPP.pod#Choosing_a_C++_Compiler and http://cpansearch.perl.org/src/NEILW/Inline-CPP-0.25/Makefile.PL If we could make these simple guesses into a super-simple module (maybe even shipped with EU::XSpp) that provides a better first guess than "g++", we'd probably be in a much more portable position already. One could always add some fancy option to parse a "standard" set of arguments to Makefile.PL/Build.PL to give control to users where necessary. The interface could be something like or a subset of: use ExtUtils::CppGuess; my $guess = ExtUtils::CppGuess->new; my $cc = $guess->from_cli(\...@argv) // $guess->from_library("-lwx") // $guess->from_config; I'm the least qualified to do this. Are there any takers? Cheers, Steffen _______________________________________________ Padre-dev mailing list Padre-dev@perlide.org http://mail.perlide.org/mailman/listinfo/padre-dev
