MeqTrees on Gentoo Linux
Note: A lot of the problems encountered with Gentoo Linux are also found in the Mac installation. It took me a considerable amount of time to find a combination of package versions that work together in order to build and run Timba. In the following I give some hints on how to overcome troubles related to the installation of MeqTrees. I have not tried getting VTK to work with MeqTrees, yet.
Package versions needed: autoconf-2.61-r2 (this one is working, see ../MacPort), qscintilla 1.7.1 or , PyQt-3.17.6
PyQwt is the biggest troublemaker, uninstall all qwt/pyqwt packages and get PyQwt 5.1.0 from here: http://pyqwt.sourceforge.net
Unpack PyQwt-5.1.0.tar.gz
cd PyQwt-5.1.0/configure
The SIP directive “template %MappedType QMemArray” must be commented out in the file sip/qwt4qt3/common/QwtMemArray.sip.
Run python configure --debug -3 -Q ../qwt-5.1 - wait until it finishes with "Great, run make or nmake to build and install PyQwt"
Run make & make install
Now you should be all set to install Timba without problems and run MeqTrees
After installation one can do an emerge -uDv to bring the system back to the most current state, which will probably only emerge autoconf.
