3About mdocml, the portable mandoc distribution
4----------------------------------------------
5The mandoc manpage compiler toolset is a suite of tools compiling
6mdoc(7), the roff(7) macro language of choice for BSD manual pages,
7and man(7), the predominant historical language for UNIX manuals.
8It includes a man(1) manual viewer and additional tools.
9For general information, see <http://mdocml.bsd.lv/>.

22Installation
23------------
24Before manually installing mandoc on your system, please check
25whether the newest version of mandoc is already installed by default
26or available via a binary package or a ports system.  A list of the
27latest bundled and ported versions of mandoc for various operating
28systems is maintained at <http://mdocml.bsd.lv/ports.html>.
29
30Regarding how packages and ports are maintained for your operating
31system, please consult your operating system documentation.
32To install mandoc manually, the following steps are needed:
33
341. If you want to build the CGI program, man.cgi(8), too, run the
35command "echo BUILD_CGI=1 > configure.local".  Then run "cp
36cgi.h.examples cgi.h" and edit cgi.h as desired.
37
382. Run "./configure".
39This script attempts autoconfiguration of mandoc for your system.
40Read both its standard output and the file "Makefile.local" it
41generates.  If anything looks wrong or different from what you
42wish, read the file "configure.local.example", create and edit
43a file "configure.local", and re-run "./configure" until the
44result seems right to you.
45
463. Run "make".
47Any POSIX-compatible make, in particular both BSD make and GNU make,
48should work.  If the build fails, look at "configure.local.example"
49and go back to step 2.
50
514. Run "make -n install" and check whether everything will be
52installed to the intended places.  Otherwise, put some *DIR or *NM*
53variables into "configure.local" and go back to step�2.
54
555. Run "sudo make install".  If you intend to build a binary
56package using some kind of fake root mechanism, you may need a
57command like "make DESTDIR=... install".  Read the *-install targets
58in the "Makefile" to understand how DESTDIR is used.
59
606. If you want to use the integrated man(1) and your system uses
61manpath(1), make sure it is configured correctly, in particular,
62it returns all directory trees where manual pages are installed.
63Otherwise, if your system uses man.conf(5), make sure it contains
64a "_whatdb" line for each directory tree, and the order of these
65lines meets your wishes.
66
677. If you compiled with database support, run the command "sudo
68makewhatis" to build mandoc.db(5) databases in all the directory
69trees configured in step 6.  Whenever installing new manual pages,
70re-run makewhatis(8) to update the databases, or apropos(1) will
71not find the new pages.
72
738. To set up a man.cgi(8) server, read its manual page.
74
75Note that some man(7) pages may contain low-level roff(7) markup
76that mandoc does not yet understand.  On some BSD systems using
77mandoc, third-party software is vetted on whether it may be formatted
78with mandoc.  If not, groff(1) is pulled in as a dependency and
79used to install a pre-formatted "catpage" instead of directly as
80manual page source.
81
82
83Understanding mandoc dependencies
84---------------------------------
85The mandoc(1), man(1), and demandoc(1) utilities have no external
86dependencies, but makewhatis(8) and apropos(1) depend on the
87following software:
88
891. The SQLite database system, see <http://sqlite.org/>.
90The recommended version of SQLite is 3.8.4.3 or newer.  The mandoc
91toolset is known to work with version 3.7.5 or newer.  Versions
92older than 3.8.3 may not achieve full performance due to the
93missing SQLITE_DETERMINISTIC optimization flag.  Versions older
94than 3.8.0 may not show full error information if opening a database
95fails due to the missing sqlite3_errstr() API.  Both are very minor
96problems, apropos(1) is fully usable with SQLite 3.7.5.  Versions
97older than 3.7.5 may or may not work, they have not been tested.
98
992. The fts(3) directory traversion functions.
100If your system does not have them, the bundled compatibility version
101will be used, so you need not worry in that case.  But be careful: the
102glibc version of fts(3) is known to be broken on 32bit platforms,
103see <https://sourceware.org/bugzilla/show_bug.cgi?id=15838>.
104If you run into that problem, set "HAVE_FTS=0" in configure.local.
105
1063. Marc Espie's ohash(3) library.
107If your system does not have it, the bundled compatibility version
108will be used, so you probably need not worry about it.
109
110
111Checking autoconfiguration quality
112----------------------------------
113If you want to check whether automatic configuration works well
114on your platform, consider the following:
115
116The mandoc package intentionally does not use GNU autoconf because
117we consider that toolset a blatant example of overengineering that
118is obsolete nowadays, since all modern operating systems are now
119reasonably close to POSIX and do not need arcane shell magic any
120longer.  If your system does need such magic, consider upgrading
121to reasonably modern POSIX-compliant tools rather than asking for
122autoconf-style workarounds.
123
124As far as mandoc is using any features not mandated by ANSI X3.159-1989
125("ANSI C") or IEEE Std 1003.1-2008 ("POSIX") that some modern systems
126do not have, we intend to provide autoconfiguration tests and
127compat_*.c implementations.  Please report any that turn out to be
128missing.  Note that while we do strive to produce portable code,
129we do not slavishly restrict ourselves to POSIX-only interfaces.
130For improved security and readability, we do use well-designed,
131modern interfaces like reallocarray(3) even if they are still rather
132uncommon, of course bundling compat_*.c implementations as needed.
133
134Where mandoc is using ANSI C or POSIX features that some systems
135still lack and that compat_*.c implementations can be provided for
136without too much hassle, we will consider adding them, too, so
137please report whatever is missing on your platform.
138
139The following steps can be used to manually check the automatic
140configuration on your platform:
141
1421. Run "make distclean".
143
1442. Run "./configure"
145
1463. Read the file "config.log".  It shows the compiler commands used
147to test the libraries installed on your system and the standard
148output and standard error output these commands produce.  Watch out
149for unexpected failures.  Those are most likely to happen if headers
150or libraries are installed in unusual places or interfaces defined
151in unusual headers.  You can also look at the file "config.h" and
152check that no "#define HAVE_*" differ from your expectations.
