[M3devel] [M3commit] CVS Update: cm3

Sat Jan 19 19:45:27 CET 2008

ps -- the need or Visual C++ referenced in the checkin coment is to "boot" -- to build a current cm3 to build the NT386GNU stuff.
Just like you need cm3 to do cross builds, except in this case both Modula-3 targets can be fully built on the same machine.
Once you build the first time, IF it was working, no Visual C++/SDK requirement.
Once a working binary distribution is available, ditto.

ps -- look at m3-sys/cminstall/src/config/NT386GNU.While it is very very similar to NT386, and even outputs foo.lib and foo.lib.sa like NT386, it uses gcc for C compilation, linking, and m3cg for the backend.It is very "GNU" in tools, but not runtime.  - Jay

It DOES use m3cc/ld/as, and mklib for building static .libs, though that could probably be gcc/ar/dlltools if I figured it out."Everything" except m3cc/m3gdb can be built with just MinGWin.Building m3cc requires MSys as well.Building m3gdb requires Cygwin.m3cg is not dependent on cygwin1.dll, nor are any other Modula-3 outputs. m3gdb is dependent on cygwin1.dll. Using Cygwin probably would work..and I could try it to see if it resolves the RTLinker problem. As well, we could have something like, in cm3.cfg you could set MINGWIN_ROOT, MSYS_ROOT, and/or CYGWIN_ROOT, to guide what tools are used, OR we can have some variable: GNU_MODE = 0 % Do not use GNU tools at all -- today's NT386GNU_MODE = 1 % Use GNU tools minimally -- today's NT386GNUGNU_MODE = 2 % Use GNU tools maximally -- not existant but probably easy Eh..I know, not great.. what do "minimally" and "maximally" mean. I think we have the problem of a) many viable choices b) want to make several of them available c) just don't know what to call things and what the interface should be. As well as an interop question, since jmpbuf does vary in size between cygwin1.dl and everything else. Further down the line, there are other linkers, other compilers, other runtimes. The design here and now might take them into consideration.Gasp..I just realized, there is also another good backend option. parse.c's approach could probably be adapted to Open Watcom AND they might even take the changes (not that I have asked, I just thought of this). And that would net you progress toward a) 32 bit MS-DOS target b) OS/2 target, c) Netware target d) gcc-free Linux target, since the support all of them.Other target possibilities include Digital Mars compiler/linker, CodeWarrior (I know, dead and all), etc. Open Watcom is probably the most interesting since it is open source...  - Jay
