EMAN2 Compilation Frequent Asked Questions
Q: I am trying to compile''' PyQt4 '''on my Linux, after I type "python configure.py", I got the error "Error: Failed to create ./qtdirs using platform linux-g++. Make sure your compiler is installed correctly and you have a working make on your PATH." How should I do?
A: That means you don't have a working qt4 qmake in your PATH. If you compiled and installed Qt4/x11 to its default path, /usr/local, it will be installed in /usr/local/Trolltech/Qt-4.3.1(if your Qt version is 4.3.1), so you need set your PATH to include /usr/local/Trolltech/Qt-4.3.1/bin, and LD_LIBRARY_PATH to include /usr/local/Trolltech/Qt-4.3.1/lib.
Q: I got compilation error when I try to compile EMAN2 on SUSE 11.0:

A: The boost.python 1.34.1 package installed by SUSE 11.0's yast has problem. This has been fixed by later boost-devel package (boost-devel-1.34.1-42.2.i586). Please do a yast update for your SUSE 11.0.
