Wonder why it even pickups /tmp? * Source directory (CMAKE_USE_DIR): "/var/tmp/portage/dev-qt/qtbase-6.5.2-r2/work/qtbase-everywhere-src-6.5.2" * Build directory (BUILD_DIR): "/var/tmp/portage/dev-qt/qtbase-6.5.2-r2/work/qtbase-everywhere-src-6.5.2_build" (note /var/tmp) CMake Error at CMakeLists.txt:58 (message): The path "/tmp/portage/dev-qt/qtbase-6.5.2-r2/work/qtbase-everywhere-src-6.5.2_build" aka I was about to say just don't use PORTAGE_TMPDIR=/tmp and use the real path, but then it seems there's some nonsense going on and I do assume you're using /var/tmp. ah, indeed, /var/tmp is mentionned. I don't know then. I can confirm i have PORTAGE_TMPDIR=/var/tmp in make.conf. the problem comes from ../work/qtbase-everywhere-src-6.5.2/CMakeLists.txt And there, CMAKE_BINARY_DIR is indeed /tmp/ instead of /var/tmp. But I dont know where this variable comes from, presumably from cmake... I don't know how to debug further. Yeah, being picky about symlinks in the build dir does not seem so great on itself, but that is something else. Could possibly be a odd quirk in cmake itself, or at most the eclass (haven't had a close look). It does work fine with e.g. PORTAGE_TMPDIR=/otherdir. "Maybe" cmake is doing something strange like trying to shorten the path, aka it finds that /tmp/dir is the same inode as /var/tmp/dir or something, then strips /var If so, then I don't really know what to do with this.

(possibly intended to simplify e.g. /dir/dir/../../dir cases) As far as qtbase goes, this was added by [1], not that the behaviour described in [2] should affect us. There's a 2nd bug, but it's either restricted or deleted, so I don't know what it was about. Either way, dropping the symlink check seems harmless so may just do that after a closer look. If someone feels like convincing upstream that the check is not needed it'd be great, albeit ball risks being tossed around when it's partly caused by cmake passing a different path than the real symlink-less one we gave to it.

It fails early on: CMake Error at CMakeLists.txt:58 (message): The path "/tmp/portage/dev-qt/qtbase-6.5.2-r2/work/qtbase-everywhere-src-6.5.2_build" contains symlinks. This is not supported. Possible solutions: - Map directories using a transparent mechanism such as mount --bind - Pass the real path of the build directory to CMake, e.g. using cd $(realpath <path>) before invoking cmake <source_dir>. Call Stack (most recent call first): CMakeLists.txt:65 (qt_internal_check_if_path_has_symlinks) Reproducible: Always Indeed /tmp is a symlink (to var/tmp, on a real, spinning, disk, / is a ssd). This is a fairly common setup on lot of desktop/servers i administer. I never had any problem with this. Does gentoo has a position on this ? I know about mount -bind, but that's more complicated because the link is not 'obvious' when using ls.
