Move libvlccore and libcompat to LDFLAGS from LIBADD An ABI change to libvlccore or libcompat will always be signaled by a change in a header file. That change will trigger a recompilation and then relinking of affected plugins. Thus, there is no need for libvlccore.la and libcompat.la to be explicit dependencies of plugins. This small hack avoids relinking every plugin whenever the libvlccore is rebuilt. 2012-09-09 15:27:10 +02:00			`AM_LIBADD = $(LIBPTHREAD)`

Do not link plugins against libvlccore explicitly We really want plugins to resolve their VLC symbols against the already loaded LibVLC core, rather than with their own version of it. Performance benefit should be neglectible, if any. Still, this will "fix" the plugin crash with static LibVLC builds (or generate a due link-time error). Anyway, this is one step toward supporting any form of static linking again. 2008-10-19 16:10:11 +02:00			`-avoid-version -module \`
