Christian Heimes added the comment: Thanks Ronald. I was not aware that macOS has dbm_open in libc. AC_CHECK_LIB() always tries to link with an external library. The macro should skip the symbol from libc. Could you please run the PR locally and upload your config.log? -- _

Ronald Oussoren added the comment: dbm_open is in libc on macOS. likely due to being in SUSv2. The implementation in libc appears to be suboptimal (for example: issue33074), although I wouldn't teach configure.ac to ignore the system version of the library. -- nosy: +ronaldoussoren

[issue45747] Detect dbm and gdbm dependencies in configure.ac

New submission from Christian Heimes : setup.py jumps through hoops to detect gdbm, gdbm_compat, ndbm, and bdb (libdb) build dependencies. I propose to simplify our support matrix and detect all dependencies in configure.ac. gdbmmodule.c uses gdbm_open() API, which is provided by gdbm.h and l
