Greetings,
I am the upstream maintainer of bogofilter, a heuristic spam filter,
with Linux and FreeBSD as the main development platforms and the
occasional test build and "make check" on OpenBSD, but really few and
far between.
I am not a member of the OpenBSD community, so I hope it's OK to send
carbon copies to people who had relevant ports Makefiles or changes in
hand recently.
It is conventional for OpenBSD to open bug reports for ports through
sendbug(1) or via bugs@? I skimmed a bit through the ports FAQ and
"Reporting problems" and a few messages randomly picked from the June
and July 2025 ports mailing list archives, and it doesn't look so.
The issue is that at least these two ports guys
- databases/lmdb
- databases/sqlite3
link against pthread these days, but their pkg-config file does not list
-lpthread when queried via pkgconfig --libs <database>.
Consequence: bogofilter itself is single-threaded and does not use
material from the POSIX threads library itself, so won't add -pthreads,
-lpthreads or similar. It does use the respective pkg-config file of
lmdb or sqlite3 for --libs and --cflags, and then fails to link any of
the database-related programs constituting bogofilter, because neither
pkg-config --libs lmdb
nor
pkg-config --libs sqlite3
gives me -lpthreads on the output. Excerpt from linker error:
ld: error: undefined symbol: pthread_mutexattr_init
referenced by sqlite3.c:29857
sqlite3.o:(pthreadMutexAlloc) in archive /usr/local/lib/libsqlite3.a
$ pkg-config --libs sqlite3
-L/usr/local/lib -lsqlite3
What I find confusing about this is that there was some effort to fix
that for sqlite3 - and I haven't built the sqlite3 from source but just
used "pkg_add sqlite3" on my OpenBSD 7.7 VM. (Which itself got updated
through several releases by way of sysupgrade followed by syspatch and
pkg_add -u):

But lmdb's .pc file definitely doesn't match that LMDB links against
pthreads these days:
