License.
So here goes release 0.1.0 of the Windows loader. It will do some
relocations and then run the program. I have successfully loaded
the Windows solitaire game. Try it. It currently stops a call to
GetObject().
WHAT'S NEW with version 0.1.0:
- Integrated patches from Alexandre.
- Minor bug fix in if1632.S
WHAT'S NEW with version 0.0.5:
- Patches from Alexandre Julliard. Some integration with Tcl.
- Generic interface for callback procedures. This will allow
callbacks into DLLs.
- MakeProcInstance() has been implemented but untested.
WHAT'S NEW with version 0.0.4:
- Eric Youngdale modified wine.c and selector.c to allow loading
of Windows DLLs.
- Added global memory allocation routines (GlobalAlloc, GlobalFree,
and GlobalLock)
- Bitmap resource loading into global memory.
WHAT'S NEW with version 0.0.3:
- Fixed bug with sector sizes.
- Registers at program startup are now set correctly.
- Segment fixups for relocatable-segment internal entry points.
- Fixed bug in DOS PSP structure.
- Some resource loading is done.
- Added "return" ordinal type to build program.
- Added comment capability to build program.
WHAT'S NEW with version 0.0.2:
- Again thanks to Eric Youngdale for some very useful comments.
- The Windows startup code created by Micrsoft C 7.0 now runs
to completion.
- Added a new patch to the kernel to increase the usable size of
the ldt to the full 32 entries currently allowed.
- Imported name relocations are now supported.
- Source code for my infamous test program is now included.
- A handful of basic Windows functions are now emulated. See
"kernel.spec" for examples of how to use the build program.
WHAT'S NEW with version 0.0.1:
- Eric Youngdale contributed countless improvements in memory
efficiency, bug fixes, and relocation.
- The build program has been completed. It now lets you specify
how the main DLL entry point should interface to your emulation
library routines. A brief description of how to build these
specifications is included in the file "build-spec.txt".
- The code to dispatch builtin DLL calls is complete, but untested.
TODO:
- Segment fixup code completion.
- Trap and handle DOS and DPMI calls.
- global memory allocation completion
- GlobalAlloc should support ZEROINIT.
- GlobalAlloc of code segments.
- complete and improve local heap allocation.
- Handle self-loading applications.
- Resource loading
INSTALLATION:
Uncompress and untar this archive into the directory of your
choice. The file "ldt.tar" contains a necessary kernel patch against
Linux 0.99.10. "ldt.tar" is unchanged from the version released
with release 0.0.2. In the directory /usr/src/linux (or whereever
you keep your kernel sources), untar this file it contains three files:
kernel/ldt.c
- This is source for a new system call.
include/linux/ldt.h
- This contains structures defining the system call
interface.
ldt.patch
- This is a patch that must be applied to the kernel.
It updates two header files, and the kernel Makefile.
BUILD:
The documentation for the build program is in the file build-spec.txt
FINALE:
Good luck,
If you successfully add anything, please send me a copy.
