Bug 381689 – dev-python/imaging-1.1.7 has hidden optional dependency on lcms

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Chris Mayo 2011-09-03 13:02:43 UTC]

imaging-1.1.7 will build with lcms support if it finds lcms installed itself.

From setup.py:
        if find_include_file(self, "lcms.h"):
            if find_library_file(self, "lcms"):
                feature.lcms = "lcms"

Suggest adding a lcms USE flag with a dependency (appears to be media-libs/lcms:0) to make this clear. Obviously that wouldn't fix the (unlikely) situation that you had lcms installed but didn't want PIL to support it.

Add lcms USE flag and disable _imagingcms.so creation if -lcms.

PIL/_imagingcms.so directly uses liblcms.so.1, not Python bindings of media-libs/lcms:0.

Reopened for Arfrever's comment 4.
