@ -2,10 +2,70 @@ Copyright Robert J. Amstadt, 1993. All code is provided without
warranty. It is my intent to cover this code with the Gnu Public
License.
So here goes release 0.2.0 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().
INSTALLATION:
Uncompress and untar this archive into the directory of your
choice. This release requires a Linux version 0.99 pl12 kernel with
ALPHA-diffs and sognal-diffs. Apply ALPHA-diffs first, and then
signal-diffs.
To build Wine, first do a "make depend" and then a "make". The
executable "wine" will be built.
WHAT'S NEW with version 0.3.0: (see ChangeLog for details)
- Mouse capture
- Text justification and underlining
- Clipping
- LoadBitmap() completed
- Code generated by the Borland compiler should now work
WHAT'S NEW with version 0.2.8: (see ChangeLog for details)
- Text functions from Alexandre
- INT 21h from Eric
- Menu improvements from David
- Bug fixes and GetProcAddress() stub from me
WHAT'S NEW with version 0.2.7: (see ChangeLog for details)
- sol.exe gets further. I did some debugging and now solitaire
stops when it tries to call GetTextExtent(). Any volunteers?
- Many DC updates from Alexandre.
- Menu updates to support underlining characters from David Metcalfe.
WHAT'S NEW with version 0.2.6: (see ChangeLog for details)
- More region updates from Alexandre
WHAT'S NEW with version 0.2.5: (see ChangeLog for details)
- Regions implemented by Alexandre
- More menuing code from me
WHAT'S NEW with version 0.2.4: (see ChangeLog for details)
- Many improvements to GDI from Alexandre
- Many improvements to menu handling by me.
WHAT'S NEW with version 0.2.3: (see ChangeLog for details)
- Bug fixes with SendMessage() and PostMessage()
- Preliminary menu support
WHAT'S NEW with version 0.2.2: (see ChangeLog for details)
- Misc bug fixes
- More bitmap code
- Timers
- Memory DC's
WHAT'S NEW with version 0.2.1:
- I have placed things into sub-directories. The organization is
not finalized. I imagine that the directory structure will
change as is necessary. Files in the ./misc directory need
to be split apart and placed in apropriate directories.
- Tons of code from Alexandre. He has constructed the framework
for handling GDI objects. He has also provided code for DCEs.
- Local heap functions have been completed.
- Bug fixes in global.c and win.c
- New function GlobalQuickAlloc() combines GlobalAlloc() and
GlobalLock() into a single function call.
- New patch kit for Linux 0.99 pl11 kernel. Thanks to Linus
who has graciously included our patches into the ALPHA patch
release cycle.
WHAT'S NEW with version 0.2.0:
- Alexandre Julliard has provided a replacement for the Tcl code.
@ -76,33 +136,9 @@ TODO:
- GlobalAlloc of code segments.
- Rewrite global memory support including kernel mods to allow
application to mess with page map.
- 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.
Or follow the same procedure with "ldt512.tar". This file contains
Eric Youngdales patches for ALPHA-pl11. These patches give the
emulator 512 ldt entries instead of the 32 available with the older
patch kit.
- Lots and lots of API fiunctions.
