Description Oleksii 2016-06-05 13:55:40 UTC

Hello there!

I want to prepare mipsel-unknown-linux-gnu cross-mini-system.

Later I have found that all target applications with enabled C++ support (USE flag cxx) unable to compile under portage (mipsel-unknown-linux-gnu-emerge) with new toolchain.

I tried to compile base target applications manually by CLFS book with ./configure string from portage
It was pretty good without any errors.

I start investigation and found, that after stage4 for crossdev in /usr/bin symlink for mipsel-unknown-linux-gnu-g++ missed.

Only mipsel-unknown-linux-gnu-g++-5.3.0 available

I have switched to new gcc - no effect.
Then I created symlink manually as mipsel-unknown-linux-gnu-g++-5.3.0 --> mipsel-unknown-linux-gnu-g++ 

And issue was resolved.

Please investigate and provide patch for cross-dev.

Thank You!

Crossdev toolchain was prepared with next parameters:

GLIBC_CPU="MIPS_ISA_MIPS32" \
PORTDIR_OVERLAY="/usr/local/portage-crossdev" \
EXTRA_ECONF="--with-mips-plt --with-arch=mips32 --with-tune=mips32 --with-llsc --enable-languages=c,c++  --disable-libcilkrts" \
CFLAGS_FOR_BUILD="-march=native -O2 -mglibc" \
CXXFLAGS_FOR_BUILD="-march=native -O2 -mglibc" \
CFLAGS_FOR_TARGET="-march=mips32 -O2 -mglibc -mllsc -mfp32  -mgp32 -mllsc -mlong32" \
CXXFLAGS_FOR_TARGET="-march=mips32 -O2 -mglibc -mllsc -mfp32  -mgp32 -mllsc -mlong32" \
USE="-cilk nopie nossp" crossdev -t mipsel -v --without-headers --abis o32
