When trying to build gcc-7.3.0 the build process fails with a configure error and configure claims it cannot find boehm-gc Reproducible: Always Steps to Reproduce: 1. Simply try to build gcc-7.3.0 with something requiring boehm-gc Actual Results: Build error Expected Results: Clean Build [ebuild NS ] sys-devel/gcc-7.3.0-r3:7.3.0::gentoo [5.4.0-r4:5.4.0::gentoo, 6.4.0-r1:6.4.0::gentoo] USE="cxx fortran (multilib) nls nptl objc objc++ objc-gc openmp pch (pie) sanitize ssp vtv (-altivec) -cilk -debug -doc (-fixed-point) -go -graphite (-hardened) (-jit) (-libssp) -mpx -pgo -regression-test -vanilla" Error: checking for bdw garbage collector... checking for system boehm-gc... configure: error: system bdw-gc required but not found make[1]: *** [Makefile:19365: configure-target-libobjc] Error 1 Looks like it is related to objective-c. But: # qlist -vI boehm-gc dev-libs/boehm-gc-7.6.4 Is installed, reemerged boehm after the first fail, just to make sure.
Hi, build dev-libs/boehm-gc with USE=abi_x86_32 should help, see Bug 617788

And indeed after reemerging boehm-gc with abi_x86_32 the build works like a charm.
