- Things that you should be aware of:
-
- 1. At Sun, RPC is part of the C library. This makefile will make a library
- called rpclib.
-
- 2. I have added two other files - portmap.c and rcpinfo.c; they usually
- do not live in this directory. Also, both files
- assume that the rpc dot h files have been installed in /usr/include.
-
- portmap.c is the source to /etc/portmap, the rpc deamon which must be started
- by root before any other rpc based servers or clients.
-
- rpcinfo.c dumps the information that the portmap keeps; at Sun, it lives
- in /usr/etc/rpcinfo.
-
- 3. The rpc library was built with a post-1.1 Sun release of the compiler.
- Old compilers complain about valid C. You can make old compilers happy
- by changing some voids to ints. However, the fix to the 4.2 VAX compiler is as
- follows:
-
- trees.c:
-
- removed spurious type mismatch errors in expressions involving
- pointers to void functions, e.g., void foo(){...} void (*f)() = foo;
-

- < else if( mt12 == 0 ) break;
- ---
- > /* if right is TVOID and looks like a CALL, is not ok */
- > else if (mt2 == 0 && (p->in.right->in.op == CALL || p->in.right->in.op == UNARY CALL))
- > break;
-
- 4. The documentation is in ditroff form in subdirectory doc. It depends
- on a Sun macro package (/usr/lib/tmac/tmac.sun) which I have included.
