Hi, I'm trying to figure out why in our Gentoo builds the test fail consistently (since 2.22 at least, many arches) with something like make subdir=libidn -C libidn ..=../ tests make[2]: Entering directory '/var/tmp/portage/sys-libs/glibc-2.26-r1/work/ glibc-2.26/libidn' make[2]: *** No rule to make target '/var/tmp/portage/sys-libs/glibc-2.26-r1/ work/build-x86-x86_64-pc-linux-gnu-nptl/libidn/check-abi-libci dn.out', needed by 'tests'. Stop. make[2]: Leaving directory '/var/tmp/portage/sys-libs/glibc-2.26-r1/work/ glibc-2.26/libidn' make[1]: *** [Makefile:216: libidn/tests] Error 2 make[1]: Leaving directory '/var/tmp/portage/sys-libs/glibc-2.26-r1/work/ glibc-2.26' make: *** [Makefile:9: check] Error 2 Any hints on how to debug this? It may well be a Gentoo-specific error, but I can't see any of our 2-3 patches touch that area.
