Hi, It seems that Argyll currently needs a few trivial patches to build on OpenBSD: http://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/graphics/argyll/ One of those patches is OpenBSD ports specific, and will not work for manual builds... So those patches adapted for general use should be: https://encrypted.pcode.nl/files/temp/argyll17-dev-openbsd.patch While I'm sure OpenBSD isn't a particularly important platform for you to support, considering the patches are trivial, I'm hoping you'd consider carrying them upstream. That said, I'm still getting a build failure in plot.c: https://encrypted.pcode.nl/files/temp/argyll17-openbsd-buildfail.txt Any ideas about that one? Regards, Pascal de Bruijn
