Re: [Question #693698]: Trouble when compiling with g++-9 or g++-7

Janek Kozicki posted a new comment:
@Anton: I suggested to try clang as a way to find out what's missing for
g++-9 (his first post).

@Sacha: Right, sorry. It seems that clang 6 on ubuntu 18.04 is too old
to help us here.

I suppose that you have packages such as libgcc-9-dev and related.

This error with g++9:
/usr/include/boost/math/cstdfloat/cstdfloat_cmath.hpp:539:43: error:
'boost::math::cstdfloat::detail::float_internal128_t
boost::math::cstdfloat::detail::abs(boost::math::cstdfloat::detail::float_internal128_t)'
conflicts with a previous declaration

rings a bell, I had it once. I just don't remember right now what it was
related with.
