* When BUILD_DB is active, link apropos(1) into the mandoc binary.Ingo Schwarze2014-08-161-0/+4
| | | | | This is the first step on the way to a man(1) implementation. The new ./configure is flexible enough to make this step quite easy.
* Improve build system and autodetection.Ingo Schwarze2014-08-161-24/+364
| | | | | | | | | * Make ./configure standalone, that's what people expect. * Let people write a ./configure.local from scratch, not edit existing files. * Autodetect wchar, sqlite3, and manpath and act accordingly. * Autodetect the need for -L/usr/local/lib and -lutil. * Get rid of config.h.p{re,ost}, let ./configure only write what's needed. * Let ./configure write a Makefile.local snippet, that's quite flexible.
* work around lack of d_namlen and ALIGN/ALIGNBYTES on LinuxIngo Schwarze2014-08-111-0/+1

* Provide a fallback version of fts(3) for systems lacking it.Ingo Schwarze2014-08-111-0/+1
| | | | | | I chose the OpenBSD version because it apparently contains various bugfixes that never made it into libnbcompat. To reduce size and complexity, i stripped out the features we don't need.
* Clarifications in comments and standard output suggested byIngo Schwarze2014-08-101-0/+2

* Do not hardcode stuff in ./configure that is actually user-configurableIngo Schwarze2014-08-081-3/+2
| | | | | | in the Makefile; instead, pass it down via the environment just like CFLAGS. Nice suggestion from kristaps@ hoping to make MacOS X happier.
* Since old SQLite versions do not have sqlite3_errstr(),Ingo Schwarze2014-08-051-0/+2
| | | | | | | | | provide a dummy fallback implementation. Do not bother to decode the error, SQLite error codes are not useful enough for that to be worthwhile. Note that using sqlite3_errmsg(db) would be a bad idea: On malloc() failure, db is NULL, which would cause a segfault. Issue noticed by kristaps@.
* remove strnlen(3) compat, we no longer use itIngo Schwarze2014-08-041-1/+0
|
* let the build system cope with the recent ohash changesIngo Schwarze2014-06-201-3/+3

* Audit malloc(3)/calloc(3)/realloc(3) usage.Ingo Schwarze2014-04-231-0/+1
| | | | | | | * Change eight reallocs to reallocarray to be safe from overflows. * Change one malloc to reallocarray to be safe from overflows. * Change one calloc to reallocarray, no zeroing needed. * Change the order of arguments of three callocs (aesthetical).
* Even though strnlen(3) is required by POSIX 2008,Ingo Schwarze2014-01-041-0/+1
| | | | | | Matthias Scheler reports than Solaris 10 lacks it. While here, sort the declarations in config.h and move the headers to the top.
* Clean up feature tests:Ingo Schwarze2014-01-041-0/+45
* Split the configure steering script out of the Makefile. * Let the configure step depend on the test sources. * Clean up the test programs such that they can be run.
