[molpro-user] -nocxx option when configuring Molpro installation

The -nocxx option was introduced for 2010.1 where we were still 
supporting some systems which did not have a C++ compiler, or at least 
one modern enough for Molpro. If the option is given, any features coded 
in C++ are not available.

 From 2012.1 onwards you need a C++ compiler and the code will fail to 
link with unresolved references if you give -nocxx option. The option 
was left in 2012.1 just in case we needed to get the code working on 
some old system again, but it has been removed in the trunk and will not 
feature in any new version.

Best wishes,
