--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Christophe Lyon from comment #2) > On trunk, the error message is: > FAIL: experimental/net/internet/address/v6/members.cc (test for excess > errors) > Excess errors: > /aci-gcc-fsf/builds/gcc-fsf-gccsrc/obj-arm-none-eabi/gcc3/arm-none-eabi/ > thumb/v7ve+simd/hard/libstdc++-v3/include/experimental/io_context:602: > error: '__fdvec' is not a member of > 'std::experimental::net::v1::io_context::__reactor' Thanks, that's a completely different error (and must have been there since February when the test was added). That error will happen for any target without <poll.h>, and I would expect it to also happen for all the other experimental/net/* tests too.
