Perl and -fPIC

[Joe Ciccone]

Programs like xchat and gaim can't build their perl plugins (as shared libraries) because the DynaLoader.a library provided by perl is not linked with -fPIC.

This patch makes it so that the objects in DynaLoader.a are built with -fPIC. ​http://cross-lfs.org/~jciccone/perl-5.8.8-fPIC-1.patch

I'd like to see this go into the book before RC4.

Added in r2368.

From backscrolling through IRC, saw issues...

This fix was in the cross-lfs scripts for getting perl to build properly with -fPIC

# if not creating a shared libperl (ie useshrplib not true), still use pic
sed -i -e "s@pldlflags=''@pldlflags=\"\$cccdlflags\"@g" \
       -e "s@static_target='static'@static_target='static_pic'@g" \
   Makefile.SH

Should properly fix the issue (at least it did between perl 5.8.5, 5.8.6 ...)

Adding -Duseshrplib will do the same as you thought and build a libperl.so. I'd rather use -Duseshrplib instead of the sed.

sed works regardless of shared or static build, always. Note perl advisories concerning use of shared perl.

Fixed with Ryan's sed.
