Hello. I have noticed that the configure script fails if the CXX environment variable is set on OS X. The error message is (when CXX=/usr/bin/c++):
checking for /usr/bin/c++... no configure: error: No C++ compiler found. Unable to build Poly/ML.
This happens when CXX is set to any valid CPP compiler. I'm pretty sure it's not user error.
The configure script works fine if CXX is unset or if I bypass the check by setting check_cpp=yes, as in the following example:
check_cpp=yes CXX=/usr/bin/c++ ./configure
I have confirmed that this happens on at least one other colleague's OS X machine. We both have 10.6 Snow Leopard. I have checked both the 5.3 release and the latest commit in SVN, and both of them display this problem.
Has anyone else encountered this problem? On other operating systems besides OS X?
It looks as though it fails in the same way on Linux. I've removed the check since the build will fail anyway if there's no C++ compiler.
