The compiled C++ libraries are located in the $OMROOT\LangCPP\lib directory:
The C++ libraries require support for C++ I/O streams. For operating systems without I/O streams (such as Windows CE™), set the _OM_NO_IOSTREAM flag in the makefile used to compile the libraries to the RHAP_FLAGS command, as follows:
RHAP_FLAGS=-D _OM_NO_IOSTREAM
