Statically build XML Parser embedded in Perl

Chaks has asked for the wisdom of the Perl Monks concerning the following question:

I am adding a module XML::Parser statically in my Perl which I build from its source. To build Parser statically I removed DynaLoader and bootstrap from Parser.pm and Expat.pm files.

I have included LINKTYPE => 'static' in Makefile.PL. It builds successfully. But when i am trying to use this module after build its throwing error as "Undefined subroutine &XML::Parser::Expat::ParserCreate called at C:/Perl/lib/XML/Parser/Expat.pm line 66."

I have linked Expat.lib to my tool and included it as newXS("XML::Parser::Expat::bootstrap", boot_XML__Parser__Expat, file)

What goes wrong after building the module statically. I tested using 'nmake test_static' which fails but 'nmake test_dynamic' passes without any error.

I have included LINKTYPE => 'static' in Makefile.PL Did you do that for both of the Makefile.PL files - ie the one in the Expat folder as well ? Like Anonymous Monk, I'm thinking that this approach might have serious problems, but I've absolutely no experience to back up that expectation ... and I notice that the error is in relation to an XML::Parser::Expat function, not XML::Parser. AFTERTHOUGHT: looks like XML::Parser itself might be pure perl, which might make the LINKTYPE setting relevant only for the Expat/Makefile.PL ... which, I'm now guessing, you've already done.

Hmm, that seems like the wrong thing to do IIRC, in theory, all you do is compile a static perl, then run `make perl` to get a new static perl when installing XML::Parser , see http://perldoc.perl.org/perlxstut.html#Dynamic-Loading-versus-Static-Loading See ALL_STATIC / BUILD_STATIC / STATIC_EXT ...

Erm ... why? What is the greater problem you want to solve and why do you think perl statically linked with XML::Parser is the solution? Jenda Enoch was right! Enjoy the last years of Rome.	[reply]
