From: Galen Henderson on 1 Apr 2010 07:16 Hello all. I tried several times to post a messge to perl.libwww but it never appeared. I am having a problem building HTML::Parser. I've pasted the original message below in case Gisle or someone here can help me out. Hello all. Hopefully Gisle is still monitoring this group. I went through the archives and found a post by him about this issue. I checked patchlevel.h and all seems well. There are no other patchlevel.h on the system. When I try to build (on OS/2), it bombs when it is trying to make the PARSERMK.DLL. with the following: weakld: error: Unresolved symbol (UNDEF EXPORT) 'boot_HTML__Parser'. weakld: info: The symbol is referenced by: U:/unixroot/galen/.cpan/build/HTML-Parser-3.64-GhzQBp/Parser.def Ignoring unresolved externals reported from weak prelinker. Error! E2028: boot_HTML__Parser is an undefined reference Error! E2044: exported symbol boot_HTML__Parser not found make: *** [blib/arch/auto/HTML/Parser/ParserMK.dll] Error 1 I can make the dll without declaring the export so it doesn't seem to be a GCC issue... When I look at the parser.c file that gets generated, there is no reference to this function. Is this supposed to be automatically added by the EXTutils functions or something else? Thanks in advance for any replies. -- Regards, Galen ------ There are only 10 kinds of people in the world. Those who understand binary and those who don't.

Do you mean the group on nntp.perl.org? I believe that server doesn't allow posting: certainly, nothing I've posted has ever shown up. You should be able to send mail to libwww-perl(a)perl.org. > I am having a problem building HTML::Parser.

E2044: exported symbol boot_HTML__Parser not found > make: *** [blib/arch/auto/HTML/Parser/ParserMK.dll] Error 1 I don't understand why this is trying to build a file called ParserMK.dll. On my system the shared library is called blib/arch/auto/HTML/Parser/Parser.so (without the 'MK'). Is this usual on OS/2? > I can make the dll without declaring the export so it doesn't seem to > be a GCC issue...

There should be a section starting XS(boot_HTML_Parser); XS(boot_HTML_Parser) { #ifdef dVAR dVAR; dXSARGS; #else dXSARGS; #endif in Parser.c. The XS() macro expands into a suitable function prototype. Is it not there? Can you run nm (or some local equivalent) on Parser.o to see if the symbol is defined? Can you post the link line(s) make is trying to use, to make sure it's picking up the right files? Ben

I haven't been building Perl modules on OS/2 for very long but from what I've seen, the MK is not added to the other dlls I've built. > > There should be a section starting > > XS(boot_HTML_Parser); > XS(boot_HTML_Parser) > { > #ifdef dVAR > dVAR; dXSARGS; > #else > dXSARGS; > #endif This is in the parser.c source file. > > in Parser.c.

Here is the gcc build command: gcc -Zdll -Zomf Parser.o -O2 -fomit-frame-pointer -falign-loops=2 -falign-jump s=2 -falign-functions=2 -s -o blib/arch/auto/HTML/Parser/ParserMK.dll \ /perl5/lib/5.10.0/os2/CORE/libperl.a -lsocket /perl5/lib/5.10.0/os2/CORE/libpe rl_override.a Parser.def \ || ( U:/PERL5/BIN/PERL.EXE -MExtUtils::Command -e 'rm_f' -- blib/arch/auto/HTM L/Parser/ParserMK.dll && sh -c false ) nm shows the symbol as _boot_HTML__Parser. I'm stumped. -- Regards, Galen ------ There are only 10 kinds of people in the world. Those who understand binary and those who don't.

I'm stumped. Me too, I'm afraid. Try building some other XS module (List::Util is provbably a good choice); if that fails in the same way, mail perl5-porters(a)perl.org; otherwise, file a bug with HTML::Parser. Ben
