[ERROR]
Either the Embedded C++ language (EC++) is enabled (option -C++e), or the compactC++ language (cC++) is enabled (option -C++c) plus the appropriate feature is disabled (option -Cn). Following features could be disabled: virtual functions templates pointer to member multiple inheritance and virtual base classes class parameters and class returns
If you really don't want to use this C++ feature, you have to find a workaround to the problem. Otherwise change the C++ language configuration with the options -C++ and -Cn, or use the advanced option dialog
