The current ebuild for lcms installs the header files in /usr/include/lcms which is not the normal location for these files (should be /usr/include). As a result every application that has a denpendancy on lcms needs to be patched or otherwise tweaked before it can be built. I have build a number of things for which there is no portage ebuild that are dependant on lcms (a GIMP color management plugin and a color profile builder - lprof) and in both cases I had to tweak the source code to get these to build because of the non-standard location of the lcms headers. There is currently a significant effort underway to bring color management to a broader range of open source systems and lcms is one of the building blocks for this effort. This will soon impact CUPS as version 1.2 will have a dependancy on lcms and as more systems become color managment aware it will impact a larger number of applications. The result is a significant number of ebuilds that are more complex than they need to be and that are therefore harder to maintain.
Created attachment 64321 [details, diff] patch to correct the location of the headers This patch should fix this bug. thanks for your report.
Yes this patch will fixes the lcms ebuild. Hopefully this will now be applied to all new lcms ebuilds.
Created attachment 64393 [details, diff] fixed patch for lcms Use this patch instead... includedir was removed from econf
These changes were commited in lcms-1.13-r2 and lcms-1.14-r1. Please test the packages. Reopen the bug if you notice some problem. Fixed Thanks
