Proposal for adding more recent rpcgen (from FreeBSD2007)

[pmusumeci@…]

Hi,

I have been helping the maintainer of the Octave package for Instrument Control get his software building on OS-X. The major issue was that rpcgen in OS-X is an older version that does not support the '-M' thread-safe code generation option. I found that a relatively recent (but not the most recent) copy of the FreeBSD sources for Sun Microsystems' rpcgen will build as-is so I would like to ask if we can have this rpcgen available as a MacPort. Could the more recent rpcgen be added to MacPorts?

Below is a small script that downloads and builds rpcgen from a 2007 era FreeBSD-current. To show the difference in use options, I have also included the help message from both rpcgen - the first is for OS-X rpcgen which mentions that it is has a SunOS 4.1 compatibility mode and the second is the more recent FreeBSD version which has the new '-M' switch and mentions FreeBSD 4.X compatibility.

Thanks,
Phillip Musumeci

# Simply download FreeBSD-current rpcgen sources and build for OS-X
# - Some octave packages require a more modern version of rpcgen. The
#   Sun Microsystems version of rpcgen as found in FreeBSD in 2007 will
#   build as-is, so we use it to replace a much earlier OS-X version.

This script will download and build rpcgen from FreeBSD

Did not realise ticket text was reformatted - here are the respective rpcgen help messages

You have to use WikiFormatting.

Might want to use the source from ​https://svnweb.freebsd.org/base/head/usr.bin/rpcgen/

[mojca (Mojca Miklavec)]

See ​https://github.com/macports/macports-ports/pull/270

[mojca (Mojca Miklavec)]

In 2f0c840119972d5a3579d6ee38423eb0c0a2e2de/macports-ports:

rpcgen-mt: new port

Mac ships its own rpcgen, but without support for the "-M" flag.

Upstream version of this software might not be available,
so we fetch it from FreeBSD's repository.

The '-mt' suffix was added to avoid a conflict with developer_cmds.

Closes: #47801
