Description Milos Ivanovic 2012-04-29 14:18:06 UTC
"ld --as-needed used to compile it and its dependencies dropped the libm link which these plugins directly needed but only linked indirectly.
The fix is to simply link them explicitly. Additionally conv-mjpeg is missing a link against libjpeg."

Above excerpt taken from

Without the above additions (which are only temporary), we get this while trying to use the streamer binary:
dlopen: /usr/lib64/xawtv/ undefined symbol: tan
dlopen: /usr/lib64/xawtv/ undefined symbol: pow

Please link the needed libraries explicitly in the build process in order to fix this efficiently.

ebuild for latest version

As a starting-off point, here's an ebuild for the latest xawtv on the 3x branch. 

This drops the patches for the previous version. Interested parties should check that that is warranted before this can be merged into the main tree.

You could make this bug depend on
(media-tv/xawtv-3.103 version bump)
There is an EAPI=5 ebuild.
