[Slackbuilds-users] libva upgrade breaks opencv

[Enguerrand de Rochefort]

Hi all,

when I try to build opencv-2.4.11 the build aborts with the following error message:

It seems libva was upgraded to version 1.5 like a week or so ago (at least that's when I installed the upgrade on my system). If I revert to version 0.31 the opencv build goes through again... not sure if this information is helpful to anyone...?
