0. Introduction
|

---------------
|
||||
Yes, Midnight Commander can be compiled for Win32 (Microsoft Windows 95, 98 and
|
||||
NT) and OS/2. It has many bugs, but is quite stable now. Maybe you can help as
|
||||
a 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.
|
||||
Please note, that Midnight Commander remains primarily a file manager for
|
||||
UNIX-like systems, so recent changes may occasionally break something.
|
||||
You should not expect that it will work on your system better than file
|
||||
managers written specifically for your OS.

Yes, Midnight Commander can be compiled for Win32 (all versions of

Microsoft Windows starting with Windows 95 for all platforms, except

||||
Windows CE). It may be tricky to compile, it may be buggy, but it should
|
||||
be usable. Maybe you can help as a beta tester or as a programmer.

1. Compiling
|
||||
------------
|
||||
|
||||
1.1. Compiler
|
||||
-------------
|
||||
If you really want to enjoy free software under your non-free OS, you should
|
||||
try free compilers. Three of them are supported: EMX (OS/2), RSX and Mingw32
|
||||
(Win32). RSX is based on EMX, and can also cross-compile for OS/2 under
|
||||
Windows. Mingw32 is conceived as a free clone for Microsoft Visual C++.
|
||||
Please note, that all above compiler are based on gcc (GNU C compiler), but
|
||||
use different libraries.
|
||||
Cygwin is not (yet) powerful enough to compile Windows-specific portion of
|
||||
the Midnight Commander, but you may try to compile MC using UNIX configuration
|
||||
files. As you can easily imagine, resulting binary will need termcap or
|
||||
terminfo and use ANSI-sequences for output which is probably not what you want.
|
||||
You may also try non-free compilers. Microsoft Visual C++ (4.0 and above),
|
||||
Borland C++ (both for Win32 and OS/2) and IBM CSet are supported. "Supported"
|
||||
means merely that there are specific makefiles for those compilers, but it
|
||||
does not even assume that you will compile MC by them out-of-box.
|
||||
If you really want to enjoy free software under your non-free OS,
|
||||
you should try free compilers. Two of them are supported: RSXNT and
|
||||
MinGW. Please visit their respective sites for more information.
|
||||
|
||||
RSXNT: http://www.mathematik.uni-bielefeld.de/~rainer/
|
||||
MinGW: http://www.mingw.org/
|
||||
|
||||
MinGW is also included with Cygwin (http://www.cygwin.com/).
|
||||
|
||||
Cygwin envirinment is so close to UNIX, that it's possible to compile
|
||||
GNU Midnight Commander in the same way as it's done in UNIX (see file
|
||||
INSTALL for details). However, you should realize that you would get a
|
||||
UNIX program that has no idea about drives, Windows-style permissions
|
||||
and some other Windows-specific features. This is not the Win32 port
|
||||
discussed in this document.
|
||||
|
||||
Skeaking of non-free compilers, Microsoft Visual C++ (4.0 and above) and
|
||||
Borland C++ are supported. "Supported" means merely that there are
|
||||
specific makefiles for those compilers, but it does not even assume that
|
||||
you will compile GNU Midnight Commander out-of-box.
|
||||
|
||||
1.2. General issues
|
||||
-------------------
|
||||
See pc/README, pc/BUGS, pc/TODO for the information concerning current state
|
||||
of the port.
|
||||
You may need to create some fake includes to compile. You may also need to
|
||||
change something in the MC sources.
|
||||
See pc/README, pc/BUGS, pc/TODO for the information concerning current
|
||||
state of the port. You may need to hack the code in order to compile it.
|
||||
|
||||
1.3 Windowing Library
|
||||
---------------------
|
||||
Currently only support for SLang windowing library is given. There are
|
||||
curses clones ported to Win32 and OS/2, but I believe that since there is
|
||||
no analogs for autoconf for those systems, we should avoid unnecessary
|
||||
Currently only support for the S-Lang windowing library is provided.
|
||||
There are curses clones ported to Win32, but I believe that since we
|
||||
are not using autoconf for the Win32 port, we should avoid unnecessary
|
||||
difficulties.
|
||||
Currently the PC port SLang included in this distribution (see slang/
|
||||
subdirectory). This is a subset of SLang 0.99.38 distribution with some
|
||||
bugs fixed. There are also MC-specific changes in the code.
|
||||
SLang 0.99.38 has problems with OS/2 if you like console with more than
|
||||
80x25 characters. You may try to use a newer SLang. It is possible, but it
|
||||
is also quite tricky.
|
||||
|
||||
Currently the Win32 port only can use S-Lang included in this
|
||||
distribution (see slang/ subdirectory). This is a subset of S-Lang
|
||||
0.99.38 distribution with some bugfixes and MC-specific code changes.
|
||||
|
||||
1.4 Features and Limitations
|
||||
----------------------------
|
||||
Internal editor is supported (including syntax highlighting).
|
||||
Internal viewer is supported (including hex editor).
|
||||
VFS (virtual file system) is not supported.
|
||||
X11 ports are not supported.
|
||||
Concurrent subshell is not supported.
|
||||
|
||||
2. Changes made
|
||||
---------------
|
||||
|
||||
2.1. Changes to main code
|
||||
-------------------------
|
||||
Changes in the main code are enclosed in #ifdef _OS_NT, __os2__ or OS2_NT
|
||||
blocks.
|
||||
Changes in the main code are enclosed in #ifdef _OS_NT blocks.
|
||||
|
||||
In some cases we suppressed 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. We
|
||||
In some cases we suppressed 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. 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 suppressed.
|
||||
- Signals: deleted. Should support the native ones.
|
||||
- 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 several files with so many changes that they have been moved to pc/
|
||||
subdirectory. Some of them are common for Win32 and OS/2, some of them are
|
||||
system-specific. System-specific files bear a clear mark in their names
|
||||
(for example, dirent_nt.c)
|
||||
Our intention should be, however, to make most code system-independent. This
|
||||
would increase code reuse and maintainability :-)

3. Authors and maintainers
|
||||
--------------------------
|
||||
This port is based on the port for Windows NT by
|
||||
Juan Grigera <grigera@isis.unlp.edu.ar>
|
||||
and the port for OS/2 by
|
||||
Alexander Dong <ado@software-ag.de>
|
||||
Both ports were merged to one PC port by me,
|
||||
Pavel Roskin <proski@gnu.org>
|
||||
Please note, that I'm using Linux now. I have access to Windows 95 machines,
|
||||
but I have no access to OS/2 machines. If you are really keen to continue my
|
||||
work, please drop me a letter.
|
||||
|
||||
Pavel Roskin <proski@gnu.org>
|
||||
The code is not actively maintained, but the patches are applied.
|
||||
Please send your changes to the mc-devel list.
