Comment 1 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-05-09 06:11:49 UTC
Actually, I had boehm-gc-7.6.0 installed.

> Actually, I had boehm-gc-7.6.0 installed.

That's surprising because above dependency is exactly what is missing.

boehm-gc got debundled from gcc-7.1.0 and it now expects an external system copy.
Installing boehm-gc prior to gcc installation fixes the configure error in the last stage.
Comment 3 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-05-09 15:29:15 UTC
Maybe it's another multilib-strict failure? i.e. try it without the lib->lib64 symlink.

    toolchain.eclass: add DEPEND to dev-libs/boehm-gc, bug #617788
    sys-devel/gcc-7.1.0 requires external dev-libs/boehm-gc, the internal
    copy got removed [1].

    dev-libs/libatomic_ops: Make multilib compatible
    Package-Manager: Portage-2.3.5, Repoman-2.3.2
Comment 6 David Seifert gentoo-dev 2017-05-11 06:41:22 UTC
Reminder: toolchain.eclass somehow needs to DEPEND on dev-libs/boehm-gc[${MULTILIB_USEDEP}] if USE=obj-gc and multilib are enabled. The short-term hack would be to check if via 'has_version' calls, which is ugly, and the long-term hack would be putting it in a proper multilib? obj-gc? () clause in DEPEND. Given the implicit nature of how toolchain works, the latter could require a significant reengineering of the toolchain eclass.
Comment 7 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-05-11 07:07:29 UTC
...or just replacing the implicit with explicit.

For the meantime, I think it would be reasonable to enable abi_x86_* by default in appropriate profiles for those packages.
Comment 8 Matthias Maier gentoo-dev 2017-05-11 07:22:23 UTC
It might be worthwhile to finally clean up toolchain.eclass (with EAPI 5, or 6 support only) for gcc-7 and introduce proper multilib support.
Comment 9 Bernie Hackett 2017-12-04 23:49:25 UTC
The multiarch / boehm-gc / gcc objc-gc issue is starting to cause issues for users since gcc 7.2 has been unmasked. See

Comment 14 Luke-Jr 2018-05-22 19:55:25 UTC
Confirmed this can be fixed by setting ABI_X86 to include both 32 and 64 for boehm-gc. So changing the dependency to include [abi_x86_32,abi_x86_64] (or appropriate for the given target) would probably be the solution.

same issue on gcc-8.2.2[multilib,obj-gc] 

will provide info on demand if needed.
Comment 19 Sven E. 2019-09-14 11:04:42 UTC
Same for 'stable' sys-devel/gcc-8.3.0-r1.
And for unstable sys-devel/gcc-9.2.0.
Comment 20 Vincent Reher 2019-11-03 16:23:44 UTC
I ran into this problem while moving away from an indiscriminate USE=abi_x86_32 in make.conf to more refined package.use settings. Here are some things I discovered:

(1) Rebuilding dev-libs/boehm-gc-8.0.4 after subtracting abi_x86_32 nevertheless results in the creation of 32 bit libraries /lib/ and /lib/ However, a /lib/ symlink is NOT created.  Also, entries in preserved_libs_registry were created for the (re)installed 32-bit libraries despite the fact that library versions were not changed.

(2) Manually creating the /lib/ symlink allowed all GCC packages > 7 to recompile during an emerge @preserved-rebuild but that did NOT clear preserved_libs_registry. However, reinstalling dev-libs/boehm-gc-8.0.4[abi_x86_32] did end up clearing preserved_libs_registry without the need for another emerge @preserved-rebuild.

(3) Not related to this bug but possibly of interest to package maintainers: according to, "starting with 8.0, libatomic_ops is only required if the compiler does not understand C atomics". Perhaps the unconditonal dependency on dev-libs/libatomic_ops in dev-libs/boehm-gc should be changed to a conditional dependency?

I am guessing that this bug is not affecting too many users.

Another user reproduced this today on IRC.

should be add a objc-gc? ( dev-libs/boehm-gc[abi_x86_64] ) etc
