[erlang-questions] can a program launched with open_port({spawn, Cmd}, Options) remain running after the port closes?

[Tim Watson]

The project doesn't appear to build cleanly on mac os lion:

t4@REDACTED:erlexec $ ./configure 
configure: error: cannot find install-sh, install.sh, or shtool in config "."/config
t4@REDACTED:erlexec $ ./build 
Install dir: /usr/local/src/erlang/erlexec/install
aclocal
autoconf -i
configure.ac:19: error: possibly undefined macro: AC_PROG_LIBTOOL
     If this token and others are legitimate, please use m4_pattern_allow.
     See the Autoconf documentation.
make: *** [configure] Error 1
t4@REDACTED:erlexec $ 
t4@REDACTED:erlexec $ autoconf -V

Is there a specific version of autotools required to build and compile erlexec?

Anyway, for the time being it's not a great help as I'm writing a framework to help set up and tear down clusters for distributed testing (based largely on common test) so I want to minimise the number of dependencies as much as possible. Besides, I'm more interested in working on the remote/ssh runner+monitor next, rather than spending another age fiddling around with the script runner.

Again, this is something that linked-in drivers *can* deal with to a limited extent, and therefore I suspect that native processes will make for a very nice foundation on which to build an alternative to open_port/2.

I can't remember what it was called, but it has a port driver that handles the the external comms and so on - looked very nice, although that's not what I'm trying to do/be as my focus is on getting things in a consistent state and monitoring to make sure they stay that way through the test run, then tearing down nicely before the next phase kicks off.
