I am using cross-build, following syntax is working CFLAGS='-g -ggdb3' meson build > The arm64_armv8_linux_clang_ubuntu1804 contains paths that work with ubuntu > clang/gcc packages (and would thus be used in CI). We can't have a generic > cross file for clang because of this path limitation. If ubuntu 18.04 needs some fix up like adding the stuff to PATH etc, we could do a different stage in Travis ci. right?
