Complete source migration? #12

Closed Ringdingcoder closed 8 months ago

Ringdingcoder commented 3 years ago

What are your plans for moving over all the remaining content that was in HX 2.17 over to this repo? In particular, I'm waiting for the OS/2 16-bit stuff.

Baron-von-Riedesel commented 3 years ago

Is there really anything useful missing? If you have something concrete I'll have a closer look.

DOSXXX (from HXD16)!

Baron-von-Riedesel commented 3 years ago

Ok. I'll see if that code may be (re)published. IIRC I removed the source in v2.17, regarding it obsolete.

Ringdingcoder commented 3 years ago

I noticed that you added DOSXXX, and I am very happy about it. However, I have no idea how kernel16.lib was built, which is required for DOSCALLS. I can take the one from the HXD16217.zip package, but also in the 2.17 sources, I cannot find anything that builds it.

I can see that it is only an import library for a DLL, so it would not be that hard to re-create. I’m just surprised that there is nothing in the sources (that I can find, at least). I don’t remember how to build a Win16 implib, though. I guess studying some old manuals is in order.

Ok, I found out how it could have been created: Using Microsoft’s implib tool on krnl286.exe. This produces a lot more entries than the ones present in kernel16.lib, but they can easily be picked apart and recombined to create a slimmer library.

Baron-von-Riedesel commented 3 years ago

I guess I also used MS implib, using dpmild16.exe as source - this loader emulates a few win16 kernel functions.

By chance I just found out that wlib can create import libraries from textual specifications. I stumbled over this in the open-watcom-v2 build:

bwlib -b-n-pa -s-t-zld -ii -io test.lib @file.lbc

Where file.lbc contains lines like so:

++SETRELABS.GDI.5
