I have selected the x32 profile for my system and can build several packages with ABI_X86="x32 64" but not ABI_X86="32 x32 64". Packages are failing with the following error: ------------------------------------------- libtool: install: (cd /var/tmp/portage/dev-libs/gmp-5.1.3-r1/image//usr/lib && { ln -s -f libgmpxx.so.4.3.3 libgmpxx.so || { rm -f libgmpxx.so && ln -s libgmpxx.so.4.3.3 libgmpxx.so; }; }) libtool: install: /usr/bin/install -c .libs/libgmpxx.lai /var/tmp/portage/dev-libs/gmp-5.1.3-r1/image//usr/lib/libgmpxx.la libtool: install: warning: remember to run `libtool --finish /usr/lib' make[3]: Leaving directory '/var/tmp/portage/dev-libs/gmp-5.1.3-r1/work/gmp-5.1.3-abi_x86_32.x86' make[2]: Leaving directory '/var/tmp/portage/dev-libs/gmp-5.1.3-r1/work/gmp-5.1.3-abi_x86_32.x86' make[1]: Leaving directory '/var/tmp/portage/dev-libs/gmp-5.1.3-r1/work/gmp-5.1.3-abi_x86_32.x86' /usr/include/gmp.h /* Debug output */ MULTILIB_ABI_FLAG: abi_x86_32 CHOST/dir: i686-pc-linux-gnu/ /* End of Debug output */ ERROR: dev-libs/gmp-5.1.3-r1::gentoo failed (install phase): Flag abi_x86_32 not listed in wrapper template (/var/tmp/portage/dev-libs/gmp-5.1.3-r1/image//tmp/multilib-include/gmp.h). Please report a bug to https://bugs.gentoo.org.

Please report a bug to https://bugs.gentoo.org."; -------------------------------------------------------- As above, I have modified the multilib-build.eclass to output the variables in the section that fails. It is returning the following values for abi_x86_64: MULTILIB_ABI_FLASG => abi_x86_64 CHOST => x86_64-pc-linux-gnu (think it should be x86_64-pc-linux-gnux32 with -m64 flag) MULTILIB_ABI_FLAG => abi_x86_32 CHOST => i686-pc-linux-gnu (also maybe x86_64-pc-linux-gnux32 with -m32 flag) It fails trying to install the x86_32 binaries and exits. I also dumped the wrappers (see below). What seems to be happening is that this code is checking for the wrong strings: --------------- if ! grep -q "${MULTILIB_ABI_FLAG} " "${wrapper}" then die "Flag ${MULTILIB_ABI_FLAG} not listed in wrapper template (${wrapper}). Please report a bug to https://bugs.gentoo.org." fi --------------- This doesn't trigger die() on x86_64 because said file has the following lines: #if defined(__x86_64__) /* amd64 */ # if defined(__ILP32__) /* x32 ABI */ # error "abi_x86_x32 not supported by the package." # else /* 64-bit ABI */ # error "abi_x86_64 not supported by the package." # endif #elif defined(__i386__) /* plain x86 */ # error "abi_x86_32 not supported by the package." All x86 ABIs are unsupported, but portage continues; whereas the wrapper for x86_32 is: #if defined(__x86_64__) /* amd64 */ # if defined(__ILP32__) /* x32 ABI */ # error "abi_x86_x32 not supported by the package." # else /* 64-bit ABI */ # include <x86_64-pc-linux-gnu/gmp.h> # endif #elif defined(__i386__) /* plain x86 */ # include <x86_64-pc-linux-gnu/gmp.h> Since the include line is properly defined for the abi_x86_32 wrapper, it fails here. We can also see that it is also trying to use 'x86_64-pc-linux-gnu/gmp.h' for x86_32 packages, which will probably be a source of harm. In GMPs case it would be using a gmp.h file without the following #define: #define _LONG_LONG_LIMB 1 /* which is the same for x86_x32 */ And with #define __GMP_CC "x86_64-pc-linux-gnux32-gcc -m64 -std=gnu99" /* which should be -m32 */ I also find it strange that it is trying to use the x86_64-pc-linux-gnu for anything in this system (or any x32 stage3 tar), as it could probably be better to just have: /usr/include/x32 /usr/include/32 /usr/include/64 I tried to compile other packages that have files in /usr/include/x86_64-pc-linux-gun/ and they fail the same way for ABI_X86="32 x32 64". A fix or pointers on what to do to fix this would be greatly appreciated. I stumbled upon this when trying to build the system to run on x32 but have 32bit libraries for binaries that don't compile from source yet on x32. I installed a bunch of libraries ok but before I stumbled on these: 1432509379: ::: completed emerge (1 of 1) x11-libs/libXi-1.7.4 to / 1432509441: ::: completed emerge (1 of 1) x11-libs/libXcursor-1.1.14 to / 1432511295: ::: completed emerge (1 of 2) x11-proto/scrnsaverproto-1.2.2-r1 to / 1432511317: ::: completed emerge (2 of 2) x11-libs/libXScrnSaver-1.2.2-r1 to / 1432511913: ::: completed emerge (1 of 1) dev-libs/atk-2.14.0 to / 1432511965: ::: completed emerge (1 of 2) x11-proto/compositeproto-0.4.2-r1 to / 1432511986: ::: completed emerge (2 of 2) x11-libs/libXcomposite-0.4.4-r1 to / 1432514063: ::: completed emerge (1 of 1) media-libs/alsa-lib-1.0.28 to / 1432514534: ::: completed emerge (1 of 2) x11-proto/recordproto-1.14.2-r1 to / 1432514553: ::: completed emerge (2 of 2) x11-libs/libXtst-1.2.2 to / 1432514604: ::: completed emerge (1 of 2) x11-proto/randrproto-1.4.0-r1 to / 1432514624: ::: completed emerge (2 of 2) x11-libs/libXrandr-1.4.2 to / Reproducible: Always Steps to Reproduce: 1. eselect profile to x32 abi 2. ABI_X86_32="32 x32 64" emerge gmp 3. Actual Results: Package compiles but fails to install when it wants to isntall abi_x86_32 files. Expected Results: Should install files to the correct directories.
This is because of: # Hack for emul-linux-x86 compatibility. # It assumes amd64 will come after x86, and will use amd64 # headers if no specific x86 headers were installed. if [[ ${ABI} == amd64 ]]; then sed -e "/abi_x86_32 /s&error.*&include <${CHOST}${f}>&" \ -i "${wrapper}" || die fi I guess the x32 profile you're using doesn't respect the usual x86-then-amd64 order. On the other hand, we can probably remove the hack anyway these days since emul-linux-x86 are no longer supported.
This happens for me on the following packages media-libs/libogg dev-libs/gmp sys-libs/db media-libs/libjpeg-turbo dev-libs/openssl dev-libs/libgpg-error sys-devel/llvm
+ 26 Jun 2015; Michał Górny <mgorny@gentoo.org> multilib-build.eclass: + Remove emul-linux-x86 hack, since emul-linux-x86 is no more. This should fix it. Please try now ;).
