I only meant to create the pull request for configure.ac, but the copy of master has a further change for your issue 138. Unfortunately I do not know how to remove this second change.
The error: expected expression is corrected by specifying c++11, since the CFLAGS use gnu I changed to the -std=gnu++11 for the c++ compiler.
The issues with gtest and sdf2imd I am still looking at, and will create a final pull request once I get it figured out.
