https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D246462 --- Comment #5 from Martin Birgmeier <d8zNeCFG@aon.at> --- Well, I can't "show the minimal example that worked and then stopped" becau= se I only inferred that it has been working at some previous time from the code = of mysql_fdw I quoted. RTLD_DEEPBIND is described in https://linux.die.net/man/3/dlopen But what you write might be the solution. Does it mean that if the library built by mysql57-client is linked with -Bsymbolic it will, when loaded, preferentially resolve the symbols it requires with those found in the libr= ary itself? Basically what is required that mysql_fdw resolves its symbols in t= he standard way (thereby normally to the libraries installed by postgresql12-client and any other libraries) and only the symbols in libmysqlclient.so should be resolved preferentially to those in libmysqlclient.so itself. If yes then the linker flags in databases/mysql57-client need to be changed. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
