I've just tested it on a clean Ubuntu 20.04 docker with only RISC-V toolchain, no ccache and indeed compilation works. Both directly with meson and via test-meson-builds.sh. Seems like ccache is parsed in special way by meson as using any other unknown command just fails meson configuration. Also setting CC/CXX env variable makes meson bail (even if I use the cross-file value), so I'm not sure if there is a better way to do it. Acked-by: Stanislaw Kardach <k...@semihalf.com>
