from time to time when I have done a "emerge --jobs" and zlib has been in the packages that should be emerge it fails, and mostly seems to do so under certain system loads and so on. The problem seems to be that for some reason ./configure adds -L zlib.a to LDFLAGS, but sometimes the buildsystem is ready to compile zlib.so.1.2.5 before it has finished zlib, leading to a failure due to a missing file. Just removing the line from ./configure that adds zlib.a to LDFLAGS seems to work on my system and passes make check. Buildfailure, emerge --info and patch for configure to follow. May be worth taking this up with upstream, but I could not find a bug-report-system, and have currently not the time monitoring yet another mailinglist x86_64-pc-linux-gnu-gcc -shared

i can confirm this it fails for me with --jobs set to more than 1
Thanks for the bug report and fix, I hit this too - will add this fix to Funtoo in the next few hours. Thanks again.
This is how I implemented the parallel build fix in zlib-1.2.5-r2 in src_unpack: epatch "${FILESDIR}"/${P}-fbsd_chosts.patch # This is a parallel build fix from Gentoo Bug #319661: sed -i -e '/^LDFLAGS=/d' configure || die Seems to work quite well.
Created attachment 237625 [details, diff] patch against the zlib makefile According to Mark Adler the LDFLAGS is there for a reason wrt testing the right zlib (the just built and not the system installed), so a better fix would be to add a dependency for libz.a in the right places. Makes "make shared" an "make -j10" work here.
i dont know how current upstream versions work, but that isnt how 1.2.5 works. LDFLAGS is only used with the SHARED library ... the local tests/examples have a dedicated LDFLAGS var in the Makefile for linking against the local libz.a.
