About mdocml, the portable mandoc distribution
The mandoc manpage compiler toolset is a suite of tools compiling
mdoc(7), the roff(7) macro language of choice for BSD manual pages,
and man(7), the predominant historical language for UNIX manuals.
It includes a man(1) manual viewer and additional tools.
For general information, see <http://mdocml.bsd.lv/>.

Enjoy using the mandoc toolset!
Ingo Schwarze, Karlsruhe, March 2015
Before manually installing mandoc on your system, please check
whether the newest version of mandoc is already installed by default
or available via a binary package or a ports system. A list of the
latest bundled and ported versions of mandoc for various operating
systems is maintained at <http://mdocml.bsd.lv/ports.html>.
Regarding how packages and ports are maintained for your operating
system, please consult your operating system documentation.
To install mandoc manually, the following steps are needed:
1. If you want to build the CGI program, man.cgi(8), too, run the
command "echo BUILD_CGI=1 > configure.local". Then run "cp
cgi.h.examples cgi.h" and edit cgi.h as desired.
2. Run "./configure".
This script attempts autoconfiguration of mandoc for your system.
Read both its standard output and the file "Makefile.local" it
generates. If anything looks wrong or different from what you
wish, read the file "configure.local.example", create and edit
a file "configure.local", and re-run "./configure" until the
result seems right to you.
On Solaris 10 and earlier, you may have to run "ksh ./configure"
because the native /bin/sh lacks some POSIX features.
3. Run "make".
Any POSIX-compatible make, in particular both BSD make and GNU make,
should work. If the build fails, look at "configure.local.example"
and go back to step 2.
4. Run "make -n install" and check whether everything will be
installed to the intended places. Otherwise, put some *DIR or *NM*
variables into "configure.local" and go back to step 2.
5. Run "sudo make install". If you intend to build a binary
package using some kind of fake root mechanism, you may need a
command like "make DESTDIR=... install". Read the *-install targets
in the "Makefile" to understand how DESTDIR is used.
6. If you want to use the integrated man(1) and your system uses
manpath(1), make sure it is configured correctly, in particular,
it returns all directory trees where manual pages are installed.
Otherwise, if your system uses man.conf(5), make sure it contains
a "manpath" line for each directory tree, and the order of these
lines meets your wishes.
7. If you compiled with database support, run the command "sudo
makewhatis" to build mandoc.db(5) databases in all the directory
trees configured in step 6. Whenever installing new manual pages,
re-run makewhatis(8) to update the databases, or apropos(1) will
not find the new pages.
8. To set up a man.cgi(8) server, read its manual page.
Note that some man(7) pages may contain low-level roff(7) markup
that mandoc does not yet understand. On some BSD systems using
mandoc, third-party software is vetted on whether it may be formatted
with mandoc. If not, groff(1) is pulled in as a dependency and
used to install a pre-formatted "catpage" instead of directly as
manual page source.
Understanding mandoc dependencies
The mandoc(1), man(1), and demandoc(1) utilities only depend
on the zlib library for decompressing gzipped manual pages,
but makewhatis(8) and apropos(1) depend on the following
1. The SQLite database system, see <http://sqlite.org/>.
The recommended version of SQLite is 188.8.131.52 or newer. The mandoc
toolset is known to work with version 3.7.5 or newer. Versions
older than 3.8.3 may not achieve full performance due to the
missing SQLITE_DETERMINISTIC optimization flag. Versions older
than 3.8.0 may not show full error information if opening a database
fails due to the missing sqlite3_errstr() API. Both are very minor
problems, apropos(1) is fully usable with SQLite 3.7.5. Versions
older than 3.7.5 may or may not work, they have not been tested.
2. The fts(3) directory traversion functions.
If your system does not have them, the bundled compatibility version
will be used, so you need not worry in that case. But be careful: the
glibc version of fts(3) is known to be broken on 32bit platforms,
If you run into that problem, set "HAVE_FTS=0" in configure.local.
3. Marc Espie's ohash(3) library.
If your system does not have it, the bundled compatibility version
will be used, so you probably need not worry about it.
One of the chief design goals of the mandoc toolbox is to make
sure that nothing related to documentation requires C++.
Consequently, linking mandoc against any kind of C++ program
would defeat the purpose and is not supported.
Checking autoconfiguration quality
If you want to check whether automatic configuration works well
on your platform, consider the following:
The mandoc package intentionally does not use GNU autoconf because
we consider that toolset a blatant example of overengineering that
is obsolete nowadays, since all modern operating systems are now
reasonably close to POSIX and do not need arcane shell magic any
longer. If your system does need such magic, consider upgrading
to reasonably modern POSIX-compliant tools rather than asking for
As far as mandoc is using any features not mandated by ANSI X3.159-1989
("ANSI C") or IEEE Std 1003.1-2008 ("POSIX") that some modern systems
do not have, we intend to provide autoconfiguration tests and
compat_*.c implementations. Please report any that turn out to be
missing. Note that while we do strive to produce portable code,
we do not slavishly restrict ourselves to POSIX-only interfaces.
For improved security and readability, we do use well-designed,
modern interfaces like reallocarray(3) even if they are still rather
uncommon, of course bundling compat_*.c implementations as needed.
Where mandoc is using ANSI C or POSIX features that some systems
still lack and that compat_*.c implementations can be provided for
without too much hassle, we will consider adding them, too, so
please report whatever is missing on your platform.
The following steps can be used to manually check the automatic
configuration on your platform:
1. Run "make distclean".
2. Run "./configure"
3. Read the file "config.log". It shows the compiler commands used
to test the libraries installed on your system and the standard
output and standard error output these commands produce. Watch out
for unexpected failures. Those are most likely to happen if headers
or libraries are installed in unusual places or interfaces defined
in unusual headers. You can also look at the file "config.h" and
check that no "#define HAVE_*" differ from your expectations.
