Hi all,
many packages gives next error, while compiling in chrooted arm environment (via qemu):
Code:
/usr/bin/armv7a-hardfloat-linux-gnueabi-ar: /usr/lib/llvm/5/lib/../lib/libLLVMSupport.so.5: symbol _ZSt15__once_callable, version GLIBCXX_3.4.11 not defined in file libstdc++.so.6 with link time reference

qemu: uncaught target signal 11 (Segmentation fault) - core dumped


I updated chroot system to glibc-2.26-r6, gcc 7.2.0 and binutils-2.30, by true cross-compiling, but it does nothing, error still persists.

P.S
Also, maybe someone knows, why cross-compiler armv7a-hardfloat-linux-gnueabi-g++ 7.3.0 cannot understand old options, like -mfloat-abi=hard and some others? Is it broken? armv7a-hardfloat-linux-gnueabi-gcc from same version works fone with that option... I got messages that this options are not recognised by armv7a-hardfloat-linux-gnueabi-g++, when trying to emerge gcc 7.3.0 into arm root by true cross-compiling.

Just updated cross-armv7a-hardfloat-linux-gnueabi/gcc-7.3.0
and got this message
Code:
Auto fixing rpaths for /var/tmp/portage/cross-armv7a-hardfloat-linux-gnueabi/gcc-7.3.0/image/usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/7.3.0/libstdc++.so.6.0.24

 * QA Notice: The following files contain insecure RUNPATHs
 *  Please file a bug about this at https://bugs.gentoo.org/

maybe i get bad libLLVMSupport.so.5 because libstdc++.so.6 was wrong in cross-compilation?
