Moved the path conversion code to lx_loader.c, and use it.

Added support for import-by-name fixup records.

Fixes Watcom C's wlink.exe not loading at all.
(...and now it actually links binaries!).

cbffb2ff60
Initialize the PIB at startup.
...
Otherwise, it won't be available to DLL init code when run before the
main executable starts.
Fixes Watcom C's wlink.exe crashing because it gets a NULL command line.

b9a799e22e
Fixes to DosQueryCurrentDir().
...
This API shouldn't return a drive letter or initial path separator,
and also shouldn't leak memory.

Fixed environment/command line tables passed in at OS/2 process entry.
...
This worked before on EMX-based binaries, but this fix makes it also work
on binaries compiled with Watcom C.
2016-10-15 22:09:56 -04:00

Some APIs that Watcom's wasm.exe needs to start up.

Bunch More Work: more APIs, subprocesses, multithreading.

EMX's GCC compiler can now build hello.c when run from lx_loader!
2016-10-14 02:39:17 -04:00
Ryan C. Gordon
b4d0e571e7
Implemented some file i/o APIs and stubbed some threading primitives.
...
Now EMX's build of cpp.exe (GNU's C preprocessor) runs on Linux...granted,
it picks up the Linux /usr/include headers, but this is still a triumph!
2016-10-09 13:45:58 -04:00

086e05dd0c
DosFlatToSel() is called like any other OS/2 API.
...
I must have been reading docs for device drivers, or something...?
Now it returns the top word of the linear pointer, in hopes that this will
just get mushed back together later, knock on wood.

95d666c01b
Add native modules to the loaded modules list.
...
Otherwise we'd reload/reinit libdoscalls.so (etc) for every module!
2016-10-05 15:52:11 -04:00

Turn off some debug output. I'm sure I'll regret this soon. :)

Implemented some HFILE-related code better. tests/helloc.exe now works!
2016-10-05 15:44:29 -04:00
Ryan C. Gordon
71653286cd
Implemented some more APIs.
...
This is enough to survive emx.dll intialization and a printf("hello world")
mainline, but note that we need to properly implement DosQueryHType()
before EMX's printf() will work, though (as it currently thinks stdout isn't
open), so we're not quite through a proper C Hello World test yet.
2016-10-02 18:26:27 -04:00

Initialize the DosExitList() items' function pointers.

Ryan C. Gordon
d9823705c0
Nop out the read of the FS register in EMX's syscall interface for now.
...
Eventually, we'll maybe need to set the FS register to be a proper TIB pointer,
but I'm mostly hoping that everything else was well-behaved enough to always
use DosGetInfoBlocks() instead. Yeah, right.

Bunch More Work, mostly cleanup and organization.
...
Wanted to do this now before it gets out of hand.
Ideally, this can be used for a Winelib-like option eventually, too, where you
don't load OS/2 binaries at all but rather compile and link your OS/2-based
source code against this API reimplementation.

6220544d06
Bunch More Work on getting an EMX-based "hello world" to run.
...
It looks like most of the remaining work for that is filling in dozens of
OS/2 APIs that EMX uses at startup just so we can get to our single
printf() call. :)
