Installation instructions for GNU Midnight Commander
----------------------------------------------------
Midnight Commander is written in a portable manner and uses GNU Autoconf
for configuration, so it is expected to compile without changes on many
other operating systems.
If you are installing from an official tarball, it already contains
pre-bootstrapped autotools build system (specifically the `configure'
script). In the case that you are installing from a version control
checkout, you need to bootstrap the build system yourself first using
the `autogen.sh' script. Note that to do this you would need to install
the autotools suite first and not only direct mc build dependencies.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation, and creates
the makefiles. It also creates a file `config.status' that you can run

use ksh instead of sh.

4. You can remove the program binaries and object files from the source
directory by typing `make clean'. If you want to clean the source tree
completely, so that it contains only those files that should be packaged
in the archive, issue `make distclean'. If you've run configure in a
different directory than the source tree, distclean won't remove your
*.o and linked programs in that directory.
5. GNU Midnight Commander allows you to stay in the last current
directory after exiting MC. This is done with a shell function, the man
page has more information about this.
The file `configure.in' is used to create `configure' by a program
called `autoconf'. You only need it if you want to regenerate
`configure' using a newer version of `autoconf'.

Midnight Commander is written in a portable manner and uses GNU Autoconf
for configuration, so it is expected to compile without changes on many
other operating systems.
You will need an ANSI C Compiler (such as GCC) and glib library to
compile the source. GNU Midnight Commander now comes with the S-Lang
screen manager, a fast screen manager, but you may want to use the
already installed S-Lang or ncurses library.
If you insist on using ncurses, it's recommended to use ncurses 4.1 and
above, since the older versions don't support resizing in the xterm
window.
GNU Midnight Commander comes with the mouse support on xterms and in the
Linux console. In order to take advantage of the mouse support on the
Linux console you will need the gpm mouse server (see the section
"Obtaining related software" in this file).
Once you get gpm, compile it and install it, then you will have to
specify the `--with-gpm-mouse' flag to the configure program if you
installed it in a non-standard directory. If you installed the gpm
package under /usr or /usr/local, you don't need to specify this flag;
configure will find gpm for you. The support for mice on xterms is
always compiled in.
We are working on further enhancements to the program, but we're not
sure which ones must go first. If you would like to point us in the
Right Direction we will be glad to hear from you.
If you happen to find a feature that doesn't do what you expect, please
write to mc@lists.midnight-commander.org telling as much as you can
about the problem you're experiencing. Please don't send personal
messages to the maintainers.
If you're on a GNU/Linux system, this will install the `cons.saver'
utility, which allows the Midnight Commander to save and restore the
console contents. This utility can be installed setuid root, but it's
only needed on systems where users cannot access /dev/vcsaN, where N is
the virtual console number, on which the uses is logged on.

Compiler
--------
Porting
-------
If your C compiler is not powerful enough to compile GNU Midnight
Commander, you should report is as a bug to the GNU Midnight Commander
team. Sometimes there is no solution than upgrading to a modern and
free compiler - GCC (Compiler Collection):
Some less widespread UNIX systems like AIX or Solaris often come with their own
implementations of make and relevant parts of the toolchain necessary to build
mc. While autotools abstract a lot of platform specific issues, you might
encounter unresolved problems while using the native toolchain.
http://gcc.gnu.org/
Often, GNU tools are shipped as a part of an additional software collection
(/opt/freeware on AIX, or OpenCSW on Solaris). These tools are usually prefixed
with the letter `g', e.g. `gmake' instead of `make'. If you are not really
interested in building with the native toolchain, try to override tools causing
problems like this:
AIX
---
Currently you can not use gcc 4.2.4 (and probably other versions) on
AIX to compile the S-Lang version. Please use IBM XL C or IBM XL C/C++
instead.
If you compile a ncurses version you need to set TERM=dtterm to get
working color support. Furthermore it is important to specify the
--with-ncurses-includes/--with-ncurses-lib parameters because otherwise
mc will pick up term.h from AIX which does not work with the ncurses
library.
The AIX S-Lang build was tested with S-Lang 2.0.7. Later versions may
also work but are not tested yet.
Here is an example for S-Lang, it is assumed that the S-Lang library
is installed under /user/local and that you also want want to install
to /usr/local:
export CC=cc_r
export CXX=xlC_r
export CONFIG_SHELL=/usr/bin/bash (if installed)
export SHELL=/usr/bin/bash (if installed)

Read the INSTALL file for the complete instructions.
GNU Midnight Commander requires glib2.
GNU Midnight Commander uses the S-Lang screen library by default. It
tries the S-Lang library installed on the system. If it's not found,
the included S-Lang sources are used. It is also possible to use
ncurses as the screen library.
1. Configure the package for your system.
Normally, you just `cd' to the package main directory and type
`./configure'.
The most often needed options to configure are following:
`--prefix=PATH'
By default, `make install' will install the package's files
in `/usr/local/bin', `/usr/local/man', etc. or to `/usr/bin',
`/usr/man', etc. depending on the location of an old mc binary.
If you have none in your system, default will be `/usr/local'.
You can specify an installation prefix other than default by
giving `configure' the option `--prefix=PATH'.
`--with-screen={slang|ncurses}'
Choose the library used to manage interaction with the terminal.
`slang' means S-Lang library already installed on the system,
`ncurses' means ncurses library already installed on the system.
The installed S-Lang library is used by default if found.
You may also want to specify CFLAGS for the compiler, even if it finds
itself some defaults by typing e.g.
./configure CFLAGS=-O3
2. Type `make' to compile the package.
3. Type `make install' to install programs, data files, and
documentation. You may need to run this command as root.
If you're on a GNU/Linux system, this will install the `cons.saver'
utility, which allows the Midnight Commander to save and restore the
screen contents. This utility can be installed setuid root, but it's
only needed on systems where users cannot access /dev/vcsaN, where N is
the virtual console number, on which the uses is logged on.
If you're making a mc binary distribution for other people and want to
package the whole installed tree, use `make install DESTDIR=PATH', which
will make PATH the root for installation.
4. Type `mc' and enjoy!

Midnight Commander for QNX (not QNX Neutrino)
---------------------------------------------
1. Compiling
2. Running 'mc' under QNX
3. List of modifications on mc-4.1.33
4. TODO
5. Contact information
1. Compiling
------------
1.1 Make utility
----------------
Use 'gmake'. (This is the default 'make' under QNX 4.23+). [The old 'qmake'
cannot handle the makefiles in the mc-source.]
1.2 Configuring
---------------
If you don't have an installed TCP/IP development kit, you have to 'hide'
the library file 'socket3r.lib' (can be installed by e.g. Watcom C 10.6)
in /usr/lib or /usr/watcom/10.6/usr/lib, because the existence of this file
will confuse 'configure': it will erroneously assume you have the complete
TCP/IP development kit (with headers) and will enable compiling of the
network-related VFS code (not only tarfs).
[A patch would be required in the configure-script to check the existence
of the TCP/IP-related headers also...]
Use '--disable-nls' option, if you don't have the binary utilities of
GNU 'gettext' package (e.g. 'msgfmt'). ['--with-included-gettext' doesn't
really work in 4.1.33, there are configuration/compiling problems...]
1.3 Compiler
------------
It is advised to use Watcom C 10.6+ to compile the source, because older
compilers (e.g. 9.52) do not support some convenient/required features.
[e.g. 'ar'-compatible 'wlib',...]
1.4 "No prototype found for '<function>'" warnings
--------------------------------------------------
It is advised to use high warning level (e.g. 'CFLAGS="-w4" ./configure'),
when compiling the source, because Watcom C uses a special parameter passing
convention for functions with fixed number of arguments only. So if the
compiler doesn't see the correct prototype of a function with variable
number of arguments (like printf()), it will produce a warning about the
missing prototype, but generates function call code according to the special
parameter passing convention, not the required CDECL convention (it is used
by default for functions with variable number of arguments). So the calling
convention of the function call code and the function code itself will not
match! So you MUST provide the correct prototype for function with variable
number of arguments! (Or you can force using the stack-based calling
convention as a default, if you have the stack-call-conv version of all of the
required libraries ('<name>3s.lib')...[Watcom C 10.6 required!])
[The latest release version (4.1.33/qnx) is checked against these types of
missing prototypes...]
1.5 Tested configuration
------------------------
QNX 4.24
Watcom C 10.6 (release version, no newer beta patches)
Photon 1.12
no TCP/IP development kit (-> VFS: tarfs only!)
mc-4.1.33, mc-4.1.34
2. Running 'mc' under QNX
-------------------------
Using 'qnx*' terminals:
You cannot use your keyboard correctly, if you disable the "Full 8 bits
input" feature in the 'Options|Display bits...' dialog.
On 'qnx*' terminals 'mc' will run in black and white mode by default,
because these types of terminals use non-ANSI-compatible color sequences.
Accessing remote nodes via the native QNX-network:
[The problem exists under the older versions of 'mc' only...]
If directory panels cannot handle '//<node-id>' prefix in directory names,
use directory links in order to access remote nodes on the native QNX
network:
mkdir /net
ln -sf //1/ /net/1
...
Extension and menu files:
Default 'tar' uses 'stderr' (and not 'stdout' as its 'normal' output with
'-t' option.
Default 'tar' is not a GNU 'tar', so does not understand '-z' option.
Special key-mappings:
Restrictions of the META-? as Alt-? functionality:
[META-? as ESC-? will always work!!!]
Alt-TAB -> Ctrl-TAB (Alt-TAB reserved in Photon [1.12+])
Alt-ENTER -> Ctrl-ENTER ('qnx*' terminals only)
Alt-<uppercase letter>: doesn't work
'qansi*' terminals:
Problem [QNX 4.23+ only]: screen corruption (strange line-drawing character
set handling) on 'qansi*' terminals, if linked with mc/Slang/terminfo
terminal management. (Older versions of QNX and Slang/termcap not affected.)
This problem is solved, see the comments in slang/sldisply.c about
SLTT_TRANSP_ACS_PATCH and QNX_QANSI_SLANG_COMPAT_ACS!
other terminals:
I have tested 'mc' under QNX on 'qnx*' and 'qansi*' terminals only.
toggle panels on/off (CTRL-o):
Currently not supported, but could be implemented later...
3. List of modifications on mc-4.1.33/mc-4.1.34
-----------------------------------------------
edit/
syntax.c: (4.1.33 only, fixed in 4.1.34)
line 100,191: WCC 10.6 doesn't like "<label>: }" construct ("no statement
after the label"), modified to "<label>: /*nop*/; }".
lib/
mc.menu:
'Z' on 'tar.Z' and 'tar.z' files: '%f' -> '$1'.
mc.ext.in.qnx.diff:
QNX: modified 'mc.ext.in'. [tar -t: output to stderr,...]
(No automatic install implemented: patch must be applied before
running 'configure' [->mc.ext.in.qnx.diff!]; this patch can be not
only QNX-specific...)
Makefile.in:
'mc.ext.in.qnx.diff' added to DISTLIB.
slang/
sldisply.c:
SLTT_TRANSP_ACS_PATCH dependent code:
The problem: some terminals (e.g. QNX/qansi*) map the whole upper half of
the ASCII table to the lower half, when alt-char-set is activated with
the smacs/as string-sequence. This means, that if 0 <= ch < 128 written
to the terminal, it will be translated to (ch+128) automatically by the
terminal: so not only the line-drawing characters can be written, when
the alt-char-set is activated. It implicitly means, that space, NL, CR,
etc. characters (exactly: anything besides the "standard" line drawing
characters) cannot be written directly to the terminal, when the
alt-char-set is activated, because writing these characters doesn't cause
an implicit/temporary switching-back to the standard char-set!
The original code in SLang assumes that space, NL, CR, etc. can be
printed when alt-char-set is activated. If SLTT_TRANSP_ACS_PATCH is
defined, the modified code will not use this assumption.
[Remark: the patch-code is not the most exact solution, but works...]
QNX_QANSI_SLANG_COMPAT_ACS_PATCH dependent code:
A more OS/terminal-specific solution for the problem mentioned above
(->SLTT_TRANSP_ACS_PATCH).
If QNX_QANSI_SLANG_COMPAT_ACS is defined, the default smacs/sa, rmacs/ae,
acsc/ac [and sgr/sa, if it would be used!] command sequences will be
replaced internally with the "old style" (pre-QNX 4.23) sequences in case
of QNX/qansi terminals. Using these optional command sequences the terminal
remains compatible with the original SLang code (without using the
workaround-code enabled by defining SLTT_TRANSP_ACS_PATCH).
Remark:
Currently SLTT_TRANSP_ACS_PATCH is not auto-configured by 'configure'.
(Must be manually defined...)
There is some (QNX-specific) auto-configuration hand-coded in the source:
#ifdef SLTT_TRANSP_ACS_PATCH
# if defined(__QNX__) && defined(QNX_QANSI_SLANG_COMPAT_ACS)
# undef SLTT_TRANSP_ACS_PATCH
# endif
#else
# if defined(__QNX__) && !defined(QNX_QANSI_SLANG_COMPAT_ACS)
# define QNX_QANSI_SLANG_COMPAT_ACS 1
# endif
#endif
slutty.c:
"newtty.c_iflag &= ~(ECHO | INLCR | ICRNL);"
ECHO(0x08) is a c_lflag bit, it means PARMRK(0x08) in c_iflag. (!?!)
src/
file.c:
'do_reget' can be extern if (ENABLE_VFS && USE_NETCODE), not if (ENABLE_VFS).
find.c:
search_content():
variable 'i' "must be" 'int', not 'char'. ["i == -1": (buggy?) WCC 10.6
doesn't convert automatically (int)(-1) to (char)(-1) (GCC does), so
"comparison result always 0" warning produced. It is cleaner to define
'i' as 'int', than cast '-1' to 'char', because 'read()' returns 'int'.]
key.c:
init_key():
Call load_xtra_key_defines() and clear 'use_8th_bit_as_meta' by default
under QNX, if a 'qnx*' terminal detected. (A saved config file (mc.ini)
can override it later...)
key.h:
Declare load_xtra_key_defines().
keyxdef.c:
Provides a method to define some platform-specific additional key
mappings. (e.g. QNX terminals can handle most of META-? combinations as
ALT-?...)
(Currently not listed in doc/FILES...)
layout.c:
TIOCGWINSZ must be available (<sys/ioctl.h> included), because window-
resizing code doesn't work, if not defined.
main.c:
print_usage(): reserved name in the QNX run-time library!
print_usage() -> print_mc_usage()
mouse.c:
QNX: ncurses 1.9.8a ported to QNX doesn't provide the 'SP' pointer as a
global symbol in the library, so the keyok() emulation currently cannot
be used under QNX (4.24 & Watcom C 10.6 release version).
slint.c:
QNX: 'qansi*' terminals added to the color_terminals[] list.
subshell.c:
utilunix.c:
QNX: include <unix.h> to get prototype for exec*()!!!
[See README.QNX/Section 1.4!]
Makefile.in:
'keyxdef' module added to SRCS and OBJS.
vfs/
<mc-src-root>/
README.QNX:
QNX-specific notes...
configure (line 3369):
configure.in (line 88):
(mc-4.1.34 only)
'test x$CCOPTS = x;' => 'test "x$CCOPTS" = x;'
Makefile.in:
README.QNX added to DISTMAIN.
4. TODO
-------
Because of limited time and resources now I can define a 'wish list' only:
(maybe somebody in the QNX community can help...)
subshell support with panel switch on/off ?
mouse under Photon (with qnxm, qansi-m terminals) ?
...

az mmap(2) rendszerhívás, a fájl programtérképe olvasódik be ehelyett;
ha a rendszer nem tartalmazza az mmap(2) rendszerhívást, vagy a fájl
tartalmaz olyan műveletet, mint ami megfelel a szűrőnek, a fájlnéző egy

Kilka wewnętrznych szczegółów na temat podglądu: Na systemach, które używają
wywołania systemowego mmap(2), program mapuje pliki zamiast je ładować;
jeśli system nie obsługuje mmap(2) lub plik pasuje do któregoś z wybranych
filtrów, podgląd użyje jego rozszerzalnych buforów, dzięki temu ładując tylko
te części, do których musisz mieć aktualnie dostęp (dotyczy również
