Created attachment 530916 [details] stage2 log When I tried to compile toolchain for bare metal, I've got an error due to SSP (which should be disabled, because unsupported on bare metal ARM; ssp flag is enabled in 17.0 profile). After disabling SSP by useflags - I've got error if I tried to build C++. # USE='-ssp' crossdev --libc 2.5.0 --gcc 7.3.0-r1 -S -s4 -t arm-none-eabi Unavailable repository 'haskell' referenced by masters entry in '/var/lib/layman/graaff/metadata/layout.conf' Unavailable repository 'haskell' referenced by masters entry in '/var/lib/layman/graaff/metadata/layout.conf' - * crossdev version: 20171230 * Host Portage ARCH: amd64 * Target Portage ARCH: arm * Target System: arm-none-eabi * Stage: 4 (C/C++ compiler) * ABIs: default * binutils: binutils-[stable] * gcc: gcc-7.3.0-r1 * libc: newlib-2.5.0 * CROSSDEV_OVERLAY: /usr/local/portage-crossdev * PORT_LOGDIR: /var/log/portage * PORTAGE_CONFIGROOT: / * Portage flags: * leaving sys-devel/binutils in /usr/local/portage-crossdev * leaving sys-devel/gcc in /usr/local/portage-crossdev * leaving sys-libs/newlib in /usr/local/portage-crossdev * leaving sys-devel/gdb in /usr/local/portage-crossdev * leaving metadata/layout.conf alone in /usr/local/portage-crossdev Unavailable repository 'haskell' referenced by masters entry in '/var/lib/layman/graaff/metadata/layout.conf' Unavailable repository 'haskell' referenced by masters entry in '/var/lib/layman/graaff/metadata/layout.conf' * Log: /var/log/portage/cross-arm-none-eabi-binutils.log * Emerging cross-binutils ...

Try to sync to latest tree and update crossdev. Latest toolchain.eclass disables libstdcxx-time (bug #589672) and latest crossdev disables fortran with USE=-fortran (bug #589672)
Thanks. Crossdev-20180508 works good.
