Add lang/modula3: Critical Mass implementation of Modula-3
This is a huge port. It probably should be split into several separate
ports, but Modula-3's lack of popularity doesn't justify the large
effort that would require yet.
This port will download a "bootstrap" compiler which builds a fresh
compiler and small set of core components. The fresh compiler will
then build everything else. This includes, among other things:
* CM3 Integrated Development Environment (IDE)
* CM3 Code Generator based on gcc 4.3
* CM3 Middle- and back- ends
* CVSup (CM3 is too new to build the CVSUP already in ports)
* M3 GDB (GNU Debugger)
* M3 GUI and networking support
* M3 Quake
* some demos
* many examples
* many CM3 tools
* Caltech Parser toolset
* Full M3 library
* Lots of documentation and man pages
Intentionally left out for now: six (6) games, three (3) webdev progs,
kate (gui), sgml+deepcopy (devlib), pp (m3devtool)
This is the latest release of the Critical Mass Modula-3 (CM3) collection,
version 5.8.6, and it was released in July 2010. Days were spent
developing this port, but not so much time was developed to quality
assurance. I added a "recent" patch from upstream for network concurrency
and also modified the getaddrbyname implementation as the original one
raised IPError exceptions due to my VM not having a fully qualified
hostname and external IP address. My modification makes the exception
look up hostent with 127.0.0.1 first, then raise a new exception on error.
It seems to work, but like I said, it was not heavily tested.
Most of the programs require a running X (Trestle), which I don't have
at the moment, so they stop with an appropriate raised exception. I only
assume they work, I'll have to check later.
Right now only FreeBSD AMD64 is supported. I do not expect to attempt
to support FreeBSD i386. I will probably make an attempt to cross-compile
this on DragonFly x86-64 after appropriate patches are added. A few
months ago I nearly succeeded in porting CM3 to DragonFly and I expect to
succeed on the next attempt. If other platforms are desired, somebody
else will have to create bootstraps and any necessary patches.
This was built and poudriere-tested on FreeBSD 9.2. Only libc, libm, and
libpthread are dynamically loaded so it should build fine on FreeBSD 8.4.
I don't have access to my Redports repository ATM so I can't test FreeBSD
10+, but I will attempt to fix should it fail to build on those platforms.
Hopefully someone will find this port useful. I was surprised that
apparently the full Modula-3 compiler set has never been ported to
FreeBSD, only the ezm3 version needed to build cvsup. Modula-3 is a nice
language that probably deserved to be widely used outside of academia.
