Dear Tommi,

newer BigDFT version provides PyYaml python package to ease the reading of the BigDFT logfile.
Therefore, to compile pyyaml you need the python headers available.

Control the installation of your machine to see if the python2.7-dev pachage is correctly installed.

Unfortunately, Pyyaml package does not provide any configure script, therefore it is not possible to detect this problem before compiling.
This is not however related to the normal BigDFT usage: this is just a functionality for an extra feature: at this point of the compilation, the bigdft executable is already built.

Therefore you should have all the bigdft executables in the <builddir>/src/ dicrectory.

Do not hesitate

Thanks

Luigi
