cpp Directive

rpcgen supports C preprocessing features. rpcgen defaults to use /usr/ccs/lib/cpp as the C preprocessor. If that fails, rpcgen tries to use /lib/cpp. You can specify a library containing a different cpp to rpcgen with the -Y flag.

For example, if /usr/local/bin/cpp exists, you can specify it to rpcgen as follows:

rpcgen -Y /usr/local/bin test.x
