Bug 310969 – media-libs/opencv bundles a copy of LAPACK

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Gottfried Munda 2010-03-23 19:11:24 UTC]

OpenCV-2.0.0 bundles a copy of LAPACK (3rdparty/lapack)
Attached is a modified patch based on the patch by Anuraag Agrawal [1] to use system LAPACK. Building/Linking of bundled/system LAPACK is controlled through the cmake variable BUILD_LAPACK, which is on by default to maintain current bahviour.

Maybe someone can work this into the ebuild, unfortunately I'm not familiar with writing ebuilds at all.

best regards,

I modified the ebuild to incorporate the patch, it works fine in my local overlay. The useflag bundled-lapack controls building/linking of bundled/system LAPACK. It is set on by default w.r.t. upstream.

Maybe i can also fix the issue with bundled zlib

it seems a quite similar problem.
