Same failure for cross-arm-none-eabi/gcc-5.4.0-r3, this time it fails on both machines.
what version of newlib do you have ? i suspect it's related to this error: configure:3970: /tmp/portage/cross-arm-none-eabi/gcc-5.4.0/work/build/./gcc/xgcc -B/tmp/portage/cross-arm-none-eabi/gcc-5.4.0/work/build/./gcc/ -B/usr/arm-none-eabi/bin/ -B/usr/arm-none-eabi/lib/ -isystem /usr/arm-none-eabi/include -isystem /usr/arm-none-eabi/sys-include -o conftest -g -O2 conftest.c >&5 /usr/arm-none-eabi/lib/libg.a(lib_a-exit.o): In function `exit': /tmp/portage/cross-arm-none-eabi/newlib-2.4.0/work/newlib-2.4.0/newlib/libc/stdlib/exit.c:70: undefined reference to `_exit' collect2: error: ld returned 1 exit status

Similar error here for cross-armv7a-hardfloat-linux-gnueabi/gcc-5.4.0-r3 Any suggestions?

Bugs #515648 #560668 might be related to this bug
Bugs: #515648 #560668 indeed seems to be the same issue. My question is if there is any workaround/fix known/planned for this issue? I do not know how exactly does crossdev work, but in my undestading gcc.ebuild configure section should be different, when building it for embedded versions. I am no ebuild developer, but I think, that configure section is done by toolchain eclass. Unfortunatelly I do not know where to get sources for this eclass and how to make configurations different for different embedded platforms. I am willing to help in solving the issue, as it's urgent for me to have arm-none-eabi compiler working.
here there are, the related bugs linked properly: bug 515648 bug 560668 as far as I can see crossdev generates a wrong GCC in stage 1. The correct compiler should have this multilibs: $ arm-none-eabi-gcc -print-multi-lib .; thumb;@mthumb fpu;@mfloat-abi=hard armv6-m;@mthumb@march=armv6s-m armv7-m;@mthumb@march=armv7-m armv7e-m;@mthumb@march=armv7e-m armv7-ar/thumb;@mthumb@march=armv7 armv8-m.base;@mthumb@march=armv8-m.base armv8-m.main;@mthumb@march=armv8-m.main armv7e-m/softfp/fpv5-sp-d16;@mthumb@march=armv7e-m@mfloat-abi=softfp@mfpu=fpv5-sp-d16 armv7e-m/softfp/fpv5-d16;@mthumb@march=armv7e-m@mfloat-abi=softfp@mfpu=fpv5-d16 armv7e-m/softfp;@mthumb@march=armv7e-m@mfloat-abi=softfp@mfpu=fpv4-sp-d16 armv7e-m/fpu/fpv5-sp-d16;@mthumb@march=armv7e-m@mfloat-abi=hard@mfpu=fpv5-sp-d16 armv7e-m/fpu/fpv5-d16;@mthumb@march=armv7e-m@mfloat-abi=hard@mfpu=fpv5-d16 armv7e-m/fpu;@mthumb@march=armv7e-m@mfloat-abi=hard@mfpu=fpv4-sp-d16 armv7-ar/thumb/softfp;@mthumb@march=armv7@mfloat-abi=softfp@mfpu=vfpv3-d16 armv7-ar/thumb/fpu;@mthumb@march=armv7@mfloat-abi=hard@mfpu=vfpv3-d16 armv8-m.main/softfp/fpv5-sp-d16;@mthumb@march=armv8-m.main@mfloat-abi=softfp@mfpu=fpv5-sp-d16 armv8-m.main/softfp/fpv5-d16;@mthumb@march=armv8-m.main@mfloat-abi=softfp@mfpu=fpv5-d16 armv8-m.main/fpu/fpv5-sp-d16;@mthumb@march=armv8-m.main@mfloat-abi=hard@mfpu=fpv5-sp-d16 armv8-m.main/fpu/fpv5-d16;@mthumb@march=armv8-m.main@mfloat-abi=hard@mfpu=fpv5-d16 but the GCC generated by crossdev have only: $ arm-none-eabi-gcc -print-multi-lib .; thumb;@mthumb one should build the toolchain like [1] or [2] Copy the Eclass to your overlay [3] and change it [4] [1] http://www.freddiechopin.info/en/articles/35-arm/87-bleeding-edge-toolchain-o-co-chodzi [2] https://istarc.wordpress.com/2014/07/21/stm32f4-build-your-toolchain-from-scratch/ [3] https://devmanual.gentoo.org/general-concepts/overlay/index.html#overlay-and-eclasses [4] https://devmanual.gentoo.org/eclass-writing/index.html
I could solve the problem in a very simple way: add the following line to your /etc/portage/env/cross-arm-none-eabi/gcc.conf: EXTRA_ECONF=--disable-libstdcxx-time This will override the hardcoded opposite setting in the eclass and prevent the ebuild/configure script to fail by skipping unsuccessful tests whether to add time functions when building the stdc++ library. Since these time functions require kernel support they can't be built in an arm-none-eabi environment anyway. I have tested this patch with cross-arm-none-eabi/gcc-7.2.0 and gcc-7.3.0. Both will compile fine.
(In reply to Dominik Diesch from comment #10) > EXTRA_ECONF=--disable-libstdcxx-time Looks about right. Currently libstdcxx-time enabled unconditionally for all targets: https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/toolchain.eclass#n935 Where should we disable libstdcxx-time? For all newlib targets? (*-eabi) Or only arm? (arm*-eabi)
With new crossdev-20180120 the following command is enough to build stage4 without any modifications: # USE=-fortran crossdev -t arm-none-eabi -S -s4 Does anyone still experience build failures?

I have the same problem: checking for library containing clock_gettime... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES. cross-arm-none-eabi/gcc-7.3.0-r1::crossdev was built with the following: USE="hardened (multilib) nls nptl pch pie ssp (-altivec) -awt -cilk -cxx -debug -doc (-fixed-point) -fortran -gcj -go -graphite -jit -libssp -mpx -objc -objc++ -objc-gc -openmp -pgo -regression-test -sanitize -van illa -vtv" ABI_X86="(64)" CFLAGS="-O2 -pipe" CXXFLAGS="-O2 -pipe" The difference when building the s4 gcc is USE="+cxx +fortran +openmp +sanitize +vtv" (arguably some come from my main system gcc and could be stripped). I’ll now try with EXTRA_ECONF=--disable-libstdcxx-time.

This change ogerrides our default to --disable-libstdcxx-time on *-elf and *-eabi targets.

libstdc++ should avoid clock_gettime() and friends with #comment24 commit. crossdev disables openmp explicitly for a long while in: https://bugs.gentoo.org/489798
