Please ask your distro to write and distribute the cross files. It's simply impossible for meson to distribute them for a huge number of reasons, but basically it boils down to too many distros with too many differences. I have done basically everything I can (personally) to make this easier, including adding support for loading cross files from XDG paths (/usr/share/meson/cross, etc) > > (3) I also noted that with across build one has to set the library > install directory manually, because it defaults to the directory used > for the build machine - i.e. a i386 cross build on debian amd64 should > set the lib install directory on Debian to "lib/i386-linux-gnu" but it > sets it to "lib/x86_64-linux-gnu" There is this issue: https://github.com/mesonbuild/meson/issues/4008 This is another case that is really hard to handle because of the way different distros have handled installing x86 and x86_64 binaries on the same OS. To name a few: debian : lib/$gnu-tri/ arch : lib/ + lib32/ fedora : lib64/ + lib32/ I'm sure there are more, but getting that right all of the time is actually pretty hard. I'll look into it.
