Created attachment 445608 [details] sci-mathematics:octave-4.0.3:20160913-134139.log.bz2 To reproduce, set: LDFLAGS="... -Wl,-z,defs" As a result: libtool: link: x86_64-pc-linux-gnu-g++-5.4.0 [...] -o .libs/liboctinterp.so.3.1.1 fails with: /usr/lib/gcc/x86_64-pc-linux-gnu/5.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: corefcn/.libs/libcorefcn.a(corefcn_libcorefcn_la-c-file-ptr-stream.o): undefined reference to symbol 'gzwrite' /lib64/libz.so.1: error adding symbols: DSO missing from command line which indicates that the shared library needs to be linked to -lz. The problem is not noticed without -Wl,-z,defs because apparently -lz is implicitly linked by all programs using the library. While solving this, please also try to convince upstream into linking their shared libraries with -Wl,-z,defs (when supported by the linker) to prevent these kind of issues in the future.
Please try again. commit 430460192fa2d64c196a18b34d386d4f244f5755 Author: David Seifert <soap@gentoo.org> Date: Sat Sep 24 14:43:45 2016 +0200 sci-mathematics/octave: Fix zlib underlinking Gentoo-bug: 593670 * [QA] Add -Wl,-z,defs to LDFLAGS * Make dependency on sys-libs/zlib unconditional

Adopted to ${PN}-5.1.0-pkgbuilddir.patch with minor changes. Removed --without-OSMesa as the option is no longer available. Removed --Wl,-z defs, because upstream designed the related objects as loadable plugins.
