Bug ID: 372659
Summary: eigen-3.3 and ilm-base: type collision
Product: krita
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: krita-bugs-n...@kde.org
Reporter: got...@voidlinux.eu
Target Milestone: ---
both eigen-3.3 (https://bitbucket.org/eigen/eigen/) and ilmbase
(http://www.openexr.com/downloads.html) define a type half. When building the
calligra suite, krita fails with the following error:

With eigen-3.2 the build worked fine.

downstream Void Linux bug.
