Darrel, All, After examining the way Arch handled the building and installation of sip and python2-sip, I believe the same can be applied to the sip4-tqt package to build and provide both python2 and python3 support. I have setup the arch build of sip4-tqt to do this. It can probably be done the exact same for all distros. The build proceeds as follows: pkgbase=tde-sip4-tqt pkgname=('tde-sip' "${pkgbase}") build() { CFLAGS="${CFLAGS} -I/usr/include/tqt -I${TDEDIR}/include -I${QTDIR}/include" cd ${srcdir} # the directory holding sip4-tqt source dir ## copy source for Python3 build cp -r ${pkgbase#*-} sipPy3 ## Python3 version cd ${srcdir}/sipPy3 python configure.py CFLAGS="${CFLAGS}" LFLAGS="${LDFLAGS}" make ## Python2 version cd ${srcdir}/${pkgbase#*-} python2 configure.py CFLAGS="${CFLAGS}" LFLAGS="${LDFLAGS}" make } ## package Python3 version as 'tde-sip' package_tde-sip() { pkgdesc="The TDE SIP C/C++ Bindings Generator for Python3 - Trinity upstream GIT version" depends=('python') replaces=('python-sip' 'sip') provides=('python-sip' 'sip') cd "${srcdir}/sipPy3" make DESTDIR="${pkgdir}" install install -Dm644 LICENSE "${pkgdir}/usr/share/licenses/${pkgname}/LICENSE" } ## package Python2 version as 'tde-sip4-tqt' package_tde-sip4-tqt() { pkgdesc="The TDE SIP C/C++ Bindings Generator for Python2 - Trinity upstream GIT version" depends=('sip' 'python2') replaces=('python2-sip') provides=('python2-sip') cd "${srcdir}/${pkgbase#*-}" make DESTDIR="${pkgdir}" install install -Dm644 LICENSE "${pkgdir}/usr/share/licenses/${pkgname}/LICENSE" # Provided by tde-sip rm "${pkgdir}/usr/bin/sip" } The resulting packages avoid the /usr/bin/sip conflict by removing the version produced by python2 in the package stage resulting in packages that install nicely together.
