While emerging kde-base/kdebase-meta in a 2-hours fresh gentoo installation, I got the following error while compiling sys-libs/zlib-1.2.8-r1 : relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC According to the "HOWTO fix -fPIC errors" page in the gentoo handbook (amd64 version), the probable source of the error is the ebuild of the sys-libs/zlib package, that should use the -fPIC option to compile (and obviously doesn't). Reproducible: Always Steps to Reproduce: 1. emerge sys-libs/zlib-1.2.8-r1 Actual Results: [removed previous part of the compile output] /bin/sh ./libtool --tag=CC --mode=compile gcc

Attach full build log. Note, that your understanding of the mentioned guide is not quite correct.
Created attachment 376368 [details] Build log
My understanding of the guide is that the source of the error can be : - broken gcc, which is unlikely - broken check, but this is not a check error - missing flag in the software - using a static archive with dynamic linking I tried the following line CFLAGS="-O2 -pipe -fPIC" emerge sys-libs/zlib which solved the error, leading to another probably unrelated (unable to read SONAME from libz.so) about which I'm currently investigating.
Looks like I was being wrong : the two issues are related, and the responsible for the bug is me. During the installation process, I did a nano mis-manipulation and removed the CHOST line. I re-writed it manually the somehow didn't put the right value in it (amd64 instead of x86_64), leading to the two bugs mentionned in this page. Correcting the value fixed the two bugs in one go (tested by removing then re-installing the package with and without the value). I'm marking the bug resolved… Sorry for the inconvenience.
