[vlc-devel] [PATCH 0/6] Fix LibVLC 4 build for Android

[zhilizhao]

Hi Alexandre,

After applying your patch set, I can build vlc-android on macOS with arch
armeabi-v7a and aarch64 successfully, except one exception: libdsm.

autoreconf: running: automake --add-missing --copy --force-missing
configure.ac:28: installing './compile'
configure.ac:38: error: required file './config.rpath' not found
configure.ac:13: installing './missing'
Makefile.am: installing './depcomp'
autoreconf: automake failed with exit status: 1
make: *** [.libdsm] Error 1

I can bypass the issue by touch config.rpath, but I don’t understand the issue, or
what config.rpath is. rpath should not matter for vlc-android since libvlc is a single
large shared library loaded directly from Java, I guess.
