Summary

0000431: PATCH : make libpng.so depend on libz.so

Description

The libpng.so generated by the vanilla libpng-1.2.8 sources does not depend on libz but requires applications to explicitly link with libz.

Most linux distributions seem to patch libpng to fix this (at least Debian, Gentoo, Redhat). The attached patch does this for buildroot

Additional Information

There also appears to be a difference in the glibc / uClibc loader behaviour : I am in the process of porting a custom built glibc system to buildroot / uClibc. In the previous version libpng was built with no patches but glibc could loaded zlib when the calling library (sdlImage) was linked with zlib.
This did not work with uClibc

Dependency chain extract :
No patch: (ok with glibc, ko with ucLibc)
pygame -> sdlImage -> libpng
-> libz

With patch (ok always)
pygame -> sdlImage -> libpng -> libz
-> libz

Notes
(0002568) bernhardf 07-08-07 04:16	This really sounds like a bug to me (in sdlimage or pygame). Suppose i have no need for compression, why would you want to force pulling in libz upon me? Fix pygame or sdlimage instead.
