Created attachment 617952 [details, diff] proposed fix The uim configure script, when building Qt5 support, will preferentially use the qmake-qt5 or qmake5 utilities, if they are found by the configure script, rather than plain "qmake". The Gentoo Qt packages seem to only install "qmake". This is normally not a problem as the other utilities do not exist in a typical Gentoo installation so the configure script falls back to "qmake". However, in a prefixed installation, the configure script can and does find these utilities on the host system and it will use them instead of the prefixed qmake. This ends up with the build system pulling in libraries from the host system and the results are not pretty. Configuring with _QMAKE5 pointing to the gentoo-installed qmake, as in the attached patch, disables the probing for qmake-qt5 and resolves the issue. (A similar issue exists for uim's qt4 support but I think it is irrelevant to the ebuild as qt4 is disabled) Portage 2.3.89 (python 3.6.10-final-0,

Created attachment 617954 [details] Example of failed build due to incorrectly linking host libraries Here is an example build log of what can go wrong when building a prefixed uim. Note the line in the configure output: checking for Qt5 version of qmake... /usr/bin/qmake-qt5 The qmake-qt5 command ends up injecting -L/usr/lib64 into the linker command line and everything goes horribly wrong at the end. This detection is fixed by the above simple ebuild change enabling uim to build and work properly.
