Linking problem while building XML::Parser against libexpat

[H.Merijn Brand (procura · Accepted solution]

don't REmove. just REname for now, but yes, that should help

# mv /usr/local/lib /usr/local/_lib_

You could also change the LD= line to have -L/usr/local/pa20_64/lib in front of the list, something like

LD=$(LD) -L/usr/local/pa20_64/lib

Enjoy, Have FUN! H.Merijn

Ah, moving of the wrong libexpat files out of /usr/local/lib revealed an interesting error message.

# CC=/opt/ansic/bin/cc perl Makefile.PL INC=-I/usr/local/pa20_64/include LDDLFLAGS=-L/usr/local/pa20>
Note (probably harmless): No library found for -lexpat

Expat must be installed prior to building XML::Parser and I can't find
it in the standard library directories. You can download expat from:

http://sourceforge.net/projects/expat/

If expat is installed, but in a non-standard directory, then use the
following options to Makefile.PL:

EXPATLIBPATH=... To set the directory in which to find libexpat

EXPATINCPATH=... To set the directory in which to find expat.h

For example:

perl Makefile.PL EXPATLIBPATH=/home/me/lib EXPATINCPATH=/home/me/include

Note that if you build against a shareable library in a non-standard location
you may (on some platforms) also have to set your LD_LIBRARY_PATH environment
variable at run time for perl to find the library.


So the Module provides an extra EXPATLIBPATH and EXPATINCPATH environment variable.
I thought I read the README?
To my apology, the README doesn't mention :-(

Hey, but this works

# CC=/opt/ansic/bin/cc perl Makefile.PL EXPATINCPATH=/usr/local/pa20_64/include EXPATLIBPATH=/usr/lo>

Looks good
