note syphilis The hook_op_annotation.h file is not found by g++ I don't think it needs to find that file - the build just needs to link to /usr/lib/perl5/site_perl/5.14/i686-cygwin-threads-64int/auto/B/Hooks/OP/Annotation/libAnnotation.a. I can see that the location of that file was spelt out with: <c> -L/usr/lib/perl5/site_perl/5.14/i686-cygwin-threads-64int/auto/B/Hooks/OP/Annotation </c> But the crucial <c>-lAnnotation</c> is missing. What happened to it ? Did the 'perl Makefile.PL' step warn of "no library found for -lAnnotation" ? If it did, then the build process won't even try to link to that file. Otherwise, it's probably a case of ExtUtils-Depends forgetting to put the <c>-lAnnotation</c> in. Try opening the generated Makefile, find the 2 separate lines beginning <c>EXTRALIBS</c> and <c>LDLOADLIBS</c>, add (by hand) the <c>-lAnnotation</c> at the end of each of those 2 lines, then run 'make' again. That ghastly hack will work with any luck .... assuming that /usr/lib/perl5/site_perl/5.14/i686-cygwin-threads-64int/auto/B/Hooks/OP/Annotation/libAnotation.a (which should have been installed as part of B::Hooks::OP::Annotation) exists. Another snag might be that the order in which -lCheck and -lAnnotation are specified in those 2 lines is important. Sorry - too many dependencies for me to actually try this out for myself.
