Jump start

As with most GNUware, you can build, test, and install this program on most UNIX systems by these simple steps

csh et amici:
        setenv CC ...your favorite C or C++ compiler...
        ./configure && make all check install

sh et amici:
        CC=...your favorite C or C++ compiler...
        export CC
        ./configure && make all check install

Or in one line, if you have env (most modern UNIX systems do):

        env CC=... ./configure && make all check install

If you don't set the CC environment variable, then gcc (or cc, if gcc is not available) will be assumed.

If you wish to undo a make install, just do make uninstall; this will remove any files in system directories put there by make install.

See below for further details, and for instructions for non-UNIX systems.

Installation

dired 4.00 has been updated to use the GNU autoconf automatic configuration system for UNIX installations.

GNU autoconf is run at the maintainer's site to produce the configure script from configure.in .

The configure script is run at each installer's UNIX site to produce Makefile from Makefile.in , and config.h from config.hin. The configure script is a large (4100+ lines) Bourne shell program that investigates various aspects of the local C implementation, and records its conclusions in config.h.

For convenience and safety, the distribution includes a subdirectory named save that contains read-only copies of the files Makefile, config.h, and configure created by autoconf and make configure. This will allow recovery from a lost or damaged configure file.

Should you do a make maintainer-clean [ not recommended, except at the maintainer's site], the configure script will be deleted, and you will need recent versions of both GNU m4 and autoconf correctly installed to reconstruct things, which can be done this way:

        make -f save/Makefile reconfigure

Suitable hand-crafted config.h files are provided for non-UNIX systems, and in the unlikely event of a failure of the configure script on a UNIX system, config.h can be manually produced from a copy of config.hin with a few seconds of editing work. If you do this, remember to save a copy of your config.h under a different name, because running configure will destroy it. If you have GNU autoconf installed (the installation is very simple and source code is available from ftp://prep.ai.mit.edu/pub/gnu/autoconf- x.y .tar.gz ), you might try augmenting configure.in instead, then run autoconf, autoheader, and configure.

Thus, on UNIX, installation normally consists of just two steps (assuming a csh -compatible shell):

        setenv CC ...your favorite C or C++ compiler...
        ./configure && make all check install

If you like, add OPT='your favorite optimization flags' to the make command; by default, no optimization flags are set.

The GNU standard installation directories /usr/local/bin for binaries, and /usr/local/man/man1 for manual pages are assumed. The prefix /usr/local can be overridden by providing an alternate definition on the command line:

        make prefix=/some/other/path install

After installation, you can do

        make distclean

to restore the directories to their distribution state. You should also do this between builds for different architectures from the same source tree; neglecting to do so will almost certainly lead to failure, because the config.cache file created by configure will lead to an incorrect config.h for the next build.

UNIX Systems

The code can be compiled with either C (K&R or ISO/ANSI Standard C) or C++ compilers. With some C++ compilers, it may be necessary to supply additional switches for force the compiler to stay in C++ mode, rather than reverting to C mode (e.g., on DEC Alpha OSF/1, you must do setenv CC "cxx -x cxx" ).

On UNIX systems, the only changes that you are likely to need in the Makefile are the settings of CC and CFLAGS, and possibly, DEFINES, and if you wish to do make install, the settings of bindir, MANDIR, and MANEXT.

These programs have been successfully built and tested with C and C++ compilers and tested on these systems for the 4.00 release (106 builds):

A tour of configure.in, or why porting dired is hard

As of early July, 1998, I have now adapted 18 of my software packages to use GNU autoconf and autoheader to generate a configure script that can be run on any UNIX or POSIX system to examine the environment, set various flags in config.h, and produce a customized Makefile from Makefile.in.

When this process is successful, it is of enormous value to end users, because installation becomes a trivial one-line command. However, it is a painful process for software developers, and each package adaptation has taken me longer than I expected: for dired, my labors stretched over four long days, and involved more than a thousand builds on the systems listed above. The resulting configure.in script, at 521 lines, is almost twice as long as any of the others that I've written so far; the others range from 54 to 281 lines, with an average of 132 lines. Fortunately, very little of this labor is specific to dired: I can use much of configure.in for the next package that I adapt to GNU-style configuration.

Despite the fact that the C programming language has had American and international standards since December 14, 1989, and the draft of the C Standard was stable for at least two years before that, many vendors continue to use non-standard extensions in their header files, making compilation with a strict Standard C compiler, like the excellent lcc compiler, impossible.

There are several reasons why dired so hard to port to new architectures, reflecting the sorry divergences of almost 30 years of UNIX development, vendors' differing attempts to deal with the divergences, and frequently, careless coding and inadequate testing by vendor programming staff. The points in the list below follow the tests in configure.in approximately; those 500+ lines of tests expand into 4100+ lines of Bourne shell script to implement them. For comparison, the dired source code amounts to about 7700 lines of C (also compilable with C++).

IBM PC DOS

dired has not yet been ported to the IBM PC DOS platform.
