Jwasm for DOS

[Gunther]

I'm currently working on the compilation of Jwasm for DOS. There are 2 possible ways to go:

• Using gcc for DOS (DJGPP).
• Using the old Watcom tools.

Has anyone experiences with the Watcom tools (Open Watcom v. 1.8/1.9)? Any help and feedback is very welcome.

If you have JWasm212s_140105 there is OWDOS16.mak
if not copy this one and name it "OWDOS16.mak"

Hi Gunther,

   I have used Open Watcom FORTRAN for quite some time.  I
have used WASM and some of the tools at some point in time.
I found their FORTRAN to be a solid and versatile product.

Hi Habran,

If you have JWasm212s_140105 there is OWDOS16.mak
if not copy this one and name it "OWDOS16.mak"

I have it. The point is the Watcom tool chain (compiler, linker etc.)

Steve,

Is it free? Do you have a download link?

Hi Gunther,

Yes it's free.
Here's the link: http://openwatcom.org (oops website is down, due too maintenance  :redface:).

The development seems to be stagnant, though (last official release is 5 years ago).
Fortunately, some brave guys decided to mantained the project themselves.
http://sourceforge.net/projects/openwatcom/files/current-build/
https://github.com/open-watcom

[Gunther]

Hi anta40,

thank you for the links. I'll try to figure out the rest. Probably it will work with DJGPP. Watcom would be an additional option.

Hi,

   Google shows a number of sites.  This one looked okay.

http://sourceforge.net/projects/openwatcom/

Similar to what anta40 showed.  It is free, though at one time you
could order a CD-ROM for a nominal price to support them.  Maybe
still can when their site comes back up.

Hi nidud,

Open Watcom is an excellent tool chain for building both DOS and Windows applications.

Good to know.

However building from a DOS environment is a difficult task these days.

Yes, it is. But I think it's possible with Habran's new sources. I'll let you know what happens.

i think JwAsm started out as an open watcom project   :P

Dave,

i think JwAsm started out as an open watcom project   :P

yes, of course. That's what nidud did say in post #7:

Open Watcom is an excellent tool chain for building both DOS and Windows applications. Most (if not all) tools build by Andreas is build using OW as default. JWASM, JWLINK, and JWLIB are also forks of OW's WASM, WLINK, and WLIB.
