Looks like there is a patch for zlib-ng from OpenMandriva

https://github.com/OpenMandrivaAssociation/zlib-ng/blob/master/0001-Fix-Z_SOLO-mode.patch

from cmlfs.

For now, will allow Perl to use it's bundled zlib source:

# Ensure that we never accidentally bundle bzip2
rm -rf cpan/Compress-Raw-Bzip2/bzip2-src
sed -i '/\bzip2\-src/d' MANIFEST

from cmlfs.

Without those commands, perl builds with the bundled bzip2 and zlib source in the perl source.

I assume LFS forced perl to not use the bundled sources (zlib & bzip2) in case those bundled sources are out of date.

Main issue is incompatible zlib-ng headers causes the Compress-Raw-Zlib perl module to not compile... I can't find anyone who has built perl with zlib-ng.

I do not have enough programming experience to fix the Compress-Raw-Zlib` perl module source to work with zlib-ng

Normally when building a system from source, one would rather use the freshly built libraries than a package's bundled 3rd-party library source.

The perl source has bundled copies of the sourcecode for bzip2 and zlib. This is handy if building perl on a system that may not have bzip2 or zlib installed. Otherwise, its like compiling zlib and bzip2 twice: once for the system and again for perl.

Perl still fails. Only 2 of 7 errors fixed with patch.
