[MPlayer-dev-eng] [PATCH] proper linnking check for libcdio/cdda

[Reimar Döffinger]

Hello,
currently configure test for these succeeds even if linking does not
work. Attached is a way to fix it. I may seem overcomplicated, but
problem is that cdio test tries to run the created file, and init
function can not be tested because it needs lot of ifdefs depending on
exactly library version/whatever and other functions crash without init
first...

Greetings,
Reimar Döffinger
