https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202594 Bug ID: 202594 Summary: Fix graphics/darktable build with clang 3.7.0 Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: dumbbell@FreeBSD.org Reporter: dim@FreeBSD.org Flags: maintainer-feedback?(dumbbell@FreeBSD.org) Assignee: dumbbell@FreeBSD.org Created attachment 160248 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=160248&action=edit Avoid calling __builtin_cpu_supports() with clang During the exp-run in bug 201377, it was found that graphics/darktable gives errors with a recent clang 3.7.0 snapshot: http://package18.nyi.freebsd.org/data/headamd64PR201377-default/2015-07-31_13h29m42s/logs/errors/darktable-1.6.7.log This is because the program optionally calls __builtin_cpu_supports() to get some CPU feature flags, and while clang 3.7.0 now supports this builtin, our libgcc/libcompiler-rt does not have the required support yet. To fix this, avoid calling the builtin, if clang is used. Note that I still could not verify whether the port completely builds, since for me, it always fails with: CMake Error at data/cmake_install.cmake:76 (file): file INSTALL cannot find "/usr/work/share/dim/ports/graphics/darktable/work/.build/data/darktable.desktop". Call Stack (most recent call first): cmake_install.cmake:34 (include) This is not a clang-related problem though. It may be due to some of the dozen dependencies, but I cannot figure out which one. -- You are receiving this mail because: You are the assignee for the bug.
