Ryan C. Gordon c970615447 lxapigen.sh: Report diffs of new files instead of a weird error. 2018-07-12 01:43:54 -04:00
Ryan C. Gordon 666c2ed7e4 A DosBeep() test program. 2018-07-11 01:13:42 -04:00
Ryan C. Gordon b8f67643dc Make DosBeep volume configurable. 2018-07-10 02:00:31 -04:00
Ryan C. Gordon 1fd6bab8eb Report OS version as OS/2 Warp 4.5, not 4.0. 
It's the last official release (and even what modern spins, like ArcaOS 5,
report).
 2018-07-10 01:45:05 -04:00
Ryan C. Gordon 490702cc45 Implemented DosBeep in doscalls and a simple audio mixer in lib2ine. 2018-07-10 01:33:11 -04:00
Ryan C. Gordon 8c5d43f997 pmwin: Added a few WinIs* APIs. 2018-07-10 01:27:30 -04:00
Ryan C. Gordon e31492cc16 pmwin: Changed a bunch of printf things from "unsigned int" to "uint". 2018-07-10 01:26:40 -04:00
Ryan C. Gordon 536bf684cb Implemented more robust current dir/disk APIs. 2018-07-10 01:30:01 -04:00
Ryan C. Gordon 1ce68d5bcf GLoaderState.running shouldn't be set here. 2018-07-10 01:20:08 -04:00
Ryan C. Gordon 0894e3d69d More work on mapping OS/2 drive letters to the Unix filesystem. 2018-07-10 01:19:37 -04:00
Ryan C. Gordon 8c8f41634f lxapigen.pl: Strip whitespace from function names when parsing headers. 2018-06-29 23:38:27 -04:00
Ryan C. Gordon 25ddf52ad7 lxapigen.pl doesn't need the native dir specified on the command line now. 2018-07-03 22:47:58 -04:00
Ryan C. Gordon 0a6a7208d8 Added a perl script that will filter os2imports.pl. 
It filters out APIs that are implemented in 2ine, so you can see just what's
missing.
 2018-07-03 22:47:19 -04:00
Ryan C. Gordon afc9e0846f Fixed exepack2 decompression. 
Now 4os2.exe runs without a weird crash during startup (but still fails on a
missing API call a little later).
 2018-06-29 22:05:06 -04:00
Ryan C. Gordon ec49615ef3 Fixed incorrect stack setup in NE loader. 2018-06-27 18:52:42 -04:00
Ryan C. Gordon 14073f3361 Added a basic config file parser to lib2ine. 
This will let the app set up some state about the OS/2 "system", like what
Unix paths are mapped to which OS/2 drive letters, system vars, etc.

This reads from /etc/2ine.cfg, and then tries a copy in the user's local
config dir to add/override settings.

This mostly doesn't do anything yet, but the framework is there for adding
stuff, and the drive letter mapping is done, even if nothing is using it.

Ryan C. Gordon 9860532454 Cleanup *INFOSEG creation. 2018-06-19 13:59:21 -04:00
cracyc 35d2162ba4 fix last few export names 2018-06-19 12:05:24 -04:00
cracyc c7f212d035 build fixes 2018-06-19 11:59:46 -04:00
cracyc 8457fc0e22 Implemented a whole bunch of 16-bit APIs. OS/2 1.0's cmd.exe sort of works! 
(Most of this work was cracyc's effort, but I started tweaking it before
I thought to perform a commit.  --ryan.)
 2018-06-18 15:52:58 -04:00
cracyc 5ae85f2426 Use OS2PATH instead of Ryan's hardcoded hack. 2018-06-18 15:29:36 -04:00
Ryan C. Gordon 3e83a67d48 Let OS2APIINFO optionally take key/value pairs, use it for export names. 
This lets me remove my tcpip32 hack, and will let me export old symbols
as all caps for OS/2's use and something more sane for regular use
(like VioGetCurPos() in modern times is VIOGETCURPOS in viocalls.dll, etc).
 2018-06-17 22:21:52 -04:00
Ryan C. Gordon fcbedae5d1 Fixed comment. 2018-06-17 00:23:53 -04:00
cracyc 1b885afc0b Deal better with proc lookup into 16-bit bridge entry points. 2018-06-16 23:46:42 -04:00
cracyc a13726b2b7 Allocate the full 64k segment for the environment. 
This is read/write memory owned by the process, which can reallocate it,
which CMD.EXE does.

(FIXME comment by ryan, rest of the patch was from cracyc.)
 2018-06-16 23:45:07 -04:00
cracyc 241c4ea590 CMakeLists.txt: check for ncursesw/curses.h. 2018-06-16 23:31:51 -04:00
cracyc 38ae18c0fe Accept NE EXE type 0 or 1 (really old 16-bit OS/2 apps use 0). 2018-06-16 21:48:31 -04:00
Ryan C. Gordon a80afaa0c1 Be aggressive about saving registers in the 16-bit bridge. 
Fixes a lot of stuff.  :)
 2018-06-14 12:25:38 -04:00
Ryan C. Gordon cdaf533140 Fixed typo in Dos16Write's TRACE_NATIVE line. 2018-06-14 12:24:57 -04:00
Ryan C. Gordon 4ab1d427b7 lx_loader: deal with iterated segments in NE executables. 2018-06-13 01:46:41 -04:00
Ryan C. Gordon c659bb083a lx_dump: report NE application type and some other previously-missing flags. 2018-06-13 01:08:10 -04:00
Ryan C. Gordon ab60f82c43 lx_dump: report OS/2 EXE flags for NE modules. 2018-06-13 01:00:12 -04:00
Ryan C. Gordon 37c3cc5a0a Bunch more work on 16-bit entry points. 
Can run testargv16.exe now. This means Watcom C startup code, and Watcom's
printf(), both work.
 2018-06-07 23:48:39 -04:00
Ryan C. Gordon 36dedda17c Deal with NE binaries with a stack size of zero. 
Microsoft C 5.1's CL.EXE does this. This is valid in the NE spec.
 2018-06-07 23:44:54 -04:00
Ryan C. Gordon d82dd93262 Update testargv.c to work on older compilers, added 16-bit .exe of it. 2018-06-07 23:41:42 -04:00
Ryan C. Gordon 085b1c7ec7 Implement some 16-bit APIs that our hello16.exe needs. 2018-06-06 17:27:37 -04:00
Ryan C. Gordon bd2a9bf249 lxapigen.pl: show full diffs when changing things. 2018-06-06 17:26:20 -04:00
Ryan C. Gordon fbe6aaf432 Added a 16-bit Hello World app. 2018-06-06 17:25:47 -04:00
Ryan C. Gordon 0148811a0c lx_loader: Load 16-bit NE binaries! 
This currently only works with a simple Hello World program, but this is the
bulk of the work to 16-bit program support.

Still need some minor effort to get 16-bit DLLs working, and of course we
need to implement a ton of missing 16-bit API calls.
 2018-06-06 17:25:22 -04:00
Ryan C. Gordon bdc285797c lx_dump: Don't fail for extremely small (but valid) binaries. 
Although strictly speaking, it looks like the final OS/2 releases
will fail if the OS/2 .EXE is less than ~320 bytes, choosing to
launch it as a DOS program instead (giving you the "This is an
OS/2 executable" message from the DOS stub, comically).
 2018-06-06 17:20:30 -04:00
Ryan C. Gordon 4cbda8515b Changed asm for 16-bit missing trampolines to escape 16-bit mode first. 2018-06-06 17:17:12 -04:00
Ryan C. Gordon 8b695647db lxapigen.pl: Don't overwrite files that didn't change. 
This prevents a full rebuild every time you add an API.
 2018-06-06 16:19:24 -04:00
Ryan C. Gordon b1217b7fe0 Added docs on NE format that I found on the web. 2018-05-28 12:57:50 -04:00
Ryan C. Gordon c19db82bc8 Added script that takes a pipe from lx_dump and reports all needed symbols. 
This, with its fairly large (but incomplete) dictionary of system APIs, is
useful when you want to know that a module wants "VioWrtNCell" and not
"ordinal 52 in VIOCALLS.DLL".  :)
 2018-05-28 05:03:07 -04:00
Ryan C. Gordon 537b81f460 lx_dump: 16-bit modules should list imported modules starting at 1. 2018-05-28 03:29:40 -04:00
Ryan C. Gordon 3bde50a716 lx_dump: Finished 16-bit fixup output. 2018-05-28 02:36:50 -04:00
Ryan C. Gordon 8e2c1449ab Initial work on parsing NE (16-bit) executables. 
This is just lx_dump for now, but if some work proves out, we can load these
with lx_loader, too, and bridge the 16-bit APIs to 32-bits the same as we
do anyhow, giving us access to 16-bit OS/2 binaries.
