Hi!
For a local project I've extended ax_perl_ext.m4 to report back the
perl installation prefix as PERL_EXT_PREFIX.
I use it like this:
configure.ac:
PERL_RELATIVE_INSTALL_DIR=`echo ${PERL_EXT_LIB} | sed "s,${PERL_EXT_PREFIX},,"`
Makefile.am:
perlmodulepmdir=$(prefix)$(PERL_RELATIVE_INSTALL_DIR)/FOO
perlmodulepm_DATA=BAR.pm
perlmodulesodir=$(prefix)$(PERL_RELATIVE_INSTALL_DIR)/auto/FOO/BAR
perlmoduleso_LTLIBRARIES = BAR.la
This way I can install the perl files into DESTDIR for packaging.
Of course, if $(prefix) != $(PERL_EXT_PREFIX) in the final
installation place, it won't work.
Cheers,
Thomas
