Hi list,
It seems to me that the setqt{4,5} scripts could set PKG_CONFIG_PATH as well
as PATH. Since autotools now unconditionally use pkgconfig, if the
PKG_CONFIG_PATH is not set, configure scripts may find one version of Qt,
while make would use the other. This seems to be a problem, for example with
wireshark.
Is there any reason why PKG_CONFIG_PATH is not set in the setqt<N> scripts,
while it is set in the qt{4,5}.sh scripts in /etc/profiles.d?
I'm not sure why this is needed. There is no conflict between the .pc files in
qt4 and qt5. My path is:
PKG_CONFIG_PATH=/opt/qt/lib/pkgconfig:/opt/kde/lib/pkgconfig:/opt/kde/share/pkgconfig:/opt/qt4/lib/pkgconfig:/opt/qt5/lib/pkgconfig:/opt/xorg/lib/pkgconfig:/opt/xorg/share/pkgconfig
Both /etc/profiles.d/qt{4,5}.sh should have the right settings:
$ grep PKG /etc/profile.d/qt4.sh
pathappend /opt/qt4/lib/pkgconfig PKG_CONFIG_PATH
$ grep PKG /etc/profile.d/qt5.sh
pathappend /opt/qt5/lib/pkgconfig PKG_CONFIG_PATH
