[CIG-SHORT] pylith: friction model

[Nespoli Massimo]

Hello,

I have already used PyLith (installed via the binary), but now I would like to install a friction model from the templates (I would create a new customized material).

So I reinstalled pylith using source packages. (i'm using linux)
After running autoreconf -fi and trying to run ./configure in templates/materials, I get this error:

checking pylith/materials/ElasticMaterial.hh usability... no
checking pylith/materials/ElasticMaterial.hh presence... no
checking for pylith/materials/ElasticMaterial.hh... no
configure: error: PyLith ElasticMaterial header not found; try CPPFLAGS="-I<PyLith include dir>"

as recommended, I tried to use different CPPFLAGS without success.
how can I do to solve this error?
thanks

Best regards
