[Expat-discuss] Rebuilding Expat for ActivePerl

but I think... In order to upgrade the parser 2.31 to work with later builds
of Expat on win32..
1. I need to compile Expat_1_95_2 source files into dynamic link library
(.dll) using a .DEF file
2. I have to create/get an .xs file XSUB (perlxs) that controls the
input/output to the library produced above
3. Then I Compile the .xs using xsubpp and it builds a new library which can
work with XML::Parser 2.31
Simple really, but so far it is impossible [ for me ] to get past step 1.
I've taken out the __declspec(dllexport) from the source code so I can use
the .DEF instead, and guess that the .DEF file gets put into the library to
allow access to functions by ordinals [dynamic] rather than entry point
I can generate a stock standard .xs file using h2xs against Expat.h, then
running make.. I think I need to customize the Makefile.pl here
LIBS,PREREQ_PM etc. It always complains about not finding the library, so as
yet I cant perform make install
I assume the .xs file gets compiled into the into the library to act as a
bridge between perl and the c functions and when I call my perl subs they
talk to the interface this xsub adds to the lib.
Is there already a .DEF and .XS (even an earlier version) that I can use? Is
this the forum for this message? Can anyone share any insight?
In the mean time I'm using XML::SAX::Pureperl .. because my boss isn't so
eager as me =o)
Please advise, thanks in advance
