Midnight Commander for Windows NT and Windows '95

0. Hello
|
|
--------
|
|
Hello, this is the Midnight Commander port to Win32. It has many bugs, but is
|
|
quite stable now. Maybe you can help as an beta tester or as a programmer. In
|
|
either case you would like subscribe to mc-devel list
|
|
(see readme files in main doc on how to do this) and contact us.
|
|
|
|
1. Compiling
|
|
------------
|
|
|
|
1.1. Compiler
|
|
----------------
|
|
Microsoft Visual C++ for Windows NT (all versions, including 4.x) are supported.
|
|
In nt/makefile you can find an external makefile, and in nt/makefile.vc1.nt, vc4.nt
|
|
projects for the visual IDE. Two makefiles are add since the version 3.5.39. They
|
|
are produced from MS VC 4.x and are named as ntaxp.mak (for Windows NT AXP)
|
|
and ntint.mak (for Windows NT Intel). If you want to use them, you will have to
|
|
change the path coded in these two files.
|
|
|
|
Other compilers such as Watcom, or Borland tools should be quite
|
|
straightforward, but has not been tested.
|
|
|
|
Under Cygnus tools, apparently everything works just fine.
|
|
|
|
1.2. General issues
|
|
--------------------
|
|
Preprocessor
|
|
Define:
|
|
LIBDIR
|
|
_OS_NT - OS flag
|
|
OS2_NT - Flag for OS/2 and NT
|
|
HAVE_CONFIG_H - config.h flag
|
|
|
|
Includes:
|
|
So as to avoid chaos in include files, I decided to create some
|
|
fake includes for UNIX counterparts. The empty files you need to create are:
|
|
pwd.h grp.h
|
|
sys/param.h sys/time.h
|
|
|
|
1.3 Windowing Library
|
|
--------------------------------
|
|
Currently only support for S-lang windowing library is given. I know no curses
|
|
public library ported to Win32 consoles, and I think it is useless to port
|
|
it now. You may want to download the complete distribution it from
|
|
ftp://space.mit.edu/pub/davis.
|
|
|
|
|
|
2. Changes made
|
|
---------------
|
|
|
|
2.1. Changes to main code
|
|
-------------------------
|
|
They are enclosed in #ifdef _OS_NT or OS2_NT blocks.
|
|
|
|
Wrote something similar to statfs in UTIL.C
|
|
Wrote truncate.
|
|
Changed (almost) all references to "/" path slash with PATH_CHAR and strPATH_CHAR.
|
|
Changed name of CONTROL_FILE.
|
|
Changed name of shell and call to shell.
|
|
|
|
In some cases we supressed code. This is temporal (so that mc can compile). In
|
|
the future we will provide fake or true interfaces for these features.
|
|
- Links: creation and information on links are not supported in NT. We
|
|
should provide a fake interface for the local filesystem and
|
|
a true one for networked.
|
|
- GID/UID queries (get_user, owner, preserve UID/GID on copy, ...).
|
|
- TERMinals: all the code directly done with terminals must be supressed.
|
|
- Signals: deleted. Should support the native ones.
|
|
- pipes: had some trouble in ext.c and with error_pipes but soon will be fixed.
|
|
- Chown command: Not supported yet.
|
|
|
|
2.2. Files rewritten
|
|
--------------------
|
|
There are 3 files with so many changes that they have been moved to independent
|
|
archives (or OS dependent).
|
|
- Chmod.nt.c: this command will query and change attributes (hidden, system,
|
|
archive,...). Maybe we should write a real chmod (and also a
|
|
chown). It is not finished, but works almost fine. Look that
|
|
the stat st_mode member is filled with attributes, not modes.
|
|
- Cons.handler.nt.c: Supports same API as linux cons.handler.c. It allocates
|
|
a new console buffer and switches between the two when doing a
|
|
shell. The new allocated one is the used by Midnight commander.
|
|
(look that to make this we should also redirect standard handles)
|
|
- Key.nt.c: a static table maps Virtual Key codes to Curses-like Key codes.
|
|
Also mouse events are supported.
|
|
still preliminar.
|
|
- utilnt.c: Contains utilunix.c functions, with Win32 implementation
|
|
|
|
2.3. New files
|
|
--------------
|
|
- drive.nt.c: A Change Drive command has been implemented. Two lines
|
|
in main.c were included (in the left/right panel menus).
|
|
The funcs drive_cmd_a/b are implemented in this new file.
|
|
It will build a dialog with available drives as buttons.
|
|
bug: too many drives are not supported (think just 7). have
|
|
to rewrite to support more than one line.
|
|
|
|
- util.debug.c: developers-only utilities to trace Win32 API call error codes
|
|
- util.WinNT.c: Windows NT specific functions:
|
|
getuid(): Will check your priviledges and return 0 (root)
|
|
if you have Administrator priviledges.
|
|
- util.Win32.c: Windows NT & 95 utilities: (specific to Win32, no UNIX counterpart)
|
|
getEXEtype(): check if executable is CUI or GUI.
|
|
|
|
2.4. Changes made from me (Alexander Dong, ado@software-ag.de)
|
|
--------------------
|
|
|
|
I have hacked some codes for Windows NT AXP and NT Intel.
|
|
Drive.nt.c was rewritten for a beautiful Drive_Change dialog window.
|
|
|
|
All main source changed from me are marked with the comment /* .ado */.
|
|
|
|
I have also included two own Makefiles:
|
|
ntaxp.mak (for Windows NT Alpha) and
|
|
ntint.mak (for Windows 95/NT Intel).
|
|
You will have to change the path in these files before use them. They
|
|
are both for Microsoft Visual C++ 4.x.
