[PPL-devel] C++ preprocessor problem when installing ppl

Hello,

I am trying to install ppl in my ubuntu 12.04. But "./configure" gives me an error,

* c++ preprocessor "lib/cpp" fails sanity check*

I don't know what to do with it. I have my gcc version 4.7.2, which should be Ok to compile PPL, right?

The ubuntu is run on the virtual machine.

Do you know how to solve this problem? A quick answer would be most appreciated. The installation of PPL is necessary for my artifacts submission for a conference whose deadline is the 17th.

Thank you for your help.

p.s the confiig.log has a strange line " configure: 4332: gcc --version >& 5" which is strange because ppl documents say that it suffices to have a gcc later than 4.0.2
