Hi,
I've noticed that the new test
27_io/filesystem/path/factory/u8path-char8_t.cc
fails to compile on arm-none-eabi with default cpu/fpu, because:
/tools/arm-none-eabi/bin/ld:
/obj-arm-none-eabi/gcc3/arm-none-eabi/libstdc++-v3/src/.libs/libstdc++.a(string-inst.o):
in function `_ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEaSEOS4_':
string-inst.cc:(.text._ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEaSEOS4_[_ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEaSEOS4_]+0xf4):
undefined reference to `_ZSt15__alloc_on_moveISaIcEEvRT_S2_'
[etc...]
The one in experimental is unsupported thanks to
// { dg-require-filesystem-ts "" }
Should that be added to the version in 27_io?
Thanks,
Christophe
