FreeDOS support

If you can polish that into clean patches, we'd be glad to merge them into mainline.

Great! You made it. Will test asap.

Do you mean pull request? How to be with binaries? Also, makefile copied from unix build, but, I think, it's dirty for FreeDos with unused parts and can be stripped. But I have no experience with makefiles at all And some *.c files (maybe another ones too) are not used, I think.

Awesome, feedback is what we need here, since it tested only with one board and dosbox.

Yes.

How to be with binaries?

The simplest answer - in no way. Users who need it, can build it themselves. There's also ticket to provide binaries in "official" way: https://github.com/micropython/micropython/issues/1295 , but it likely will take a lot of time to get that done. You of course can provide binaries yourself, at your, and your users risk.

So, ideal solution would be to just use existing unix makefile and port directory (and just apply as few as possible #ifdef's to support DJGPP). If that's not possible, then having a top-level directory with minimal set of files, like for Windows, would work too.

I'd be more than happy to help you with any makefile stuff that's needed.

Are you sure this is the best solution? Cause I think, that FreeDos have very little with unix build, not about Makefile difference, but… this is very different operating systems. I think more, than win and unix are. Also, FreeDos build requires proper environment variables, so there should be readme/guide, something like in my repo right now. So it's not just easy as "make freedos".

Awesome, I will try to minimize port and will post progress here, so you can review it.

In terms of reviewing things, the best (for me) would be to put the changes on a github branch and post a link to your branch.

Of course, I need time to try minimize repo.

I'm done with minimizing as I can. I think you can review it now https://github.com/pohmelie/micropython ... er/freedos
There is some «trick» to avoid alloca.h, for example. I use -D__FreeBSD__=5 cause -DMICROPY_NO_ALLOCA=1 does not work. Hm, but probably we can just remove those #if #else #end and just #include <stdlib.h> at the end of mpconfigport.h.

Followed the instructions so far. DJGPP builds without errors.

Getting an error while building the Freedos port:

/home/johannes/djgpp/lib/gcc/i586-pc-msdosdjgpp/4.9.3/include/stddef.h:56:24: fatal error: sys/_types.h: No such file or directory
#include <sys/_types.h>
^
compilation terminated.

Used this env setting:

Code: Select all

export CROSS_COMPILE=/home/johannes/djgpp/i586-pc-msdosdjgpp/bin/
export DJGPP_GCC=/home/johannes/djgpp/bin/i586-pc-msdosdjgpp-gcc
make
