IDL Gurus,
I'm trying write a remote procedure call. To do this the
program (helloworld.c) needs to find $IDL_DIR/external/
examples/rpc/rpcidl.a. Unfortunatly, this library is not
exist - it's only a symlink to nothing. In the IDL guide
(v4.0; Chpt 24; Remote Procedure Calls) rpcidl.a is specified
in the helloworld.c program. Does anybody know why this library
doesn't exist? BTW, it's missing on DEC OSF/1 and SGI. Any
help is greatly appreciated.
Thanks,
Steve Mc
