in thread XS module build not working for Perl 5.8

With regards to 5.8.8, please see reply above. The error occurs at "make test".

With regards to 5.8.6, the error occurs at "make". I have attached the fail log below:

Re^3: XS module build not working for Perl 5.8

    The "Command failed for target 'test_dynamic'" is just make telling you something previously got an error; what was that?

    Are you building these perls yourself or getting them from some binary distribution? If the latter, do you have the same compiler as was used to build perl?

      The error is: "Error: Can't load '/eng/proj/pacsun/DEV/MyPackage/blib/arch/auto/MyPackage/MyPackage.so' for module MyPackage: ld.so.1: /eng/proj/pacsun/TOOLS/bin/perl: fatal: relocation error: file /eng/proj/pacsun/DEV/MyPackage/blib/arch/auto/MyPackage/MyPackage.so: symbol cout: referenced symbol not found at /eng/proj/pacsun/TOOLS/lib/5.8.8/sun4-solaris-thread-multi/DynaLoader.pm line 230."

      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? If so, how do I know what compiler they used?

      I'm not sure I completely understand if this is true. While running 5.6, I would routinely create XS modules using C++ code. Typically I would compile using gcc. But Perl is compiled using some C compiler i.e. not gcc. I thought the XS generated library just created machine code and that the typemap dealt with passing data to and from the C/Perl object to your C++/XS object.

        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.
