Problem with linking with lib2geom

[Matěj Pokorný]

Hi, I have problem with linking depixelize-kopf2011 against lib2geom. Here is a error log...

Tried lib2geom version 0.2.0 and current trunk, but with same result...

Any idea, what I'm doing wrong?

[Vinipsmaker (vinipsmaker)]

Which version of 2geom do you use? lib2geom is know to work on lib2geom version 0.2.0: http://downloads.sourceforge.net/project/lib2geom/lib2geom/0.2/lib2geom-0.2.0.tar.gz

It also works on Inkscape's 2geom version.

[Apteryx (maxco)]

Looks like you used a lib2geom library compiled without the GNU Scientific Library (GSL). This is not a fault in libdepixelize. Closing.

Aha, ok. Thanks for the info.
