[pacman-dev] [PATCH v2] meson: make our symlinking script more portable
We do not need the --relative case as it is dead code (we only ever link a filename without directory components). For the rest, GNU-specific ln -T does two things: - if the link name is an existing directory, ln fails instead of creating a surprising link inside the directory - if the link name is a symlink to a directory, ln treats it as a file, and due to -f, unlinks it The second case can be portably solved by ln -n, and both cases can be solved by doing what the original autotools Makefile did: rm -f && ln -s If the file exists, it will be removed. If it cannot be removed, it must be an ordinary directory, and the script aborts with an error.
