i'm trying configure postgres 9.5.4 openssl 1.1.0. configure dying because can't find ssl_library_init in openssl 1.1.0. openssl 1.1.0 provides openssl_init_ssl instead of ssl_library_init. autoconf needs check either ssl_library_init or openssl_init_ssl.
postgres uses following test:
ac_check_lib(ssl, ssl_library_init, [], [ac_msg_error([library 'ssl' required openssl])]) how modify [rule?] either ssl_library_init or openssl_init_ssl?
naively, changed configure.in following, did not work. best can tell, changes ignored (even after running autoreconf):
ac_check_lib(ssl, ssl_library_init|openssl_init_ssl, [], [ac_msg_error([library 'ssl' required openssl])]) here postgrs configure command:
$ ./configure --with-openssl --with-includes=/usr/local/ssl/include --with-libraries=/usr/local/ssl/lib here relevant entry config.log:

something should work out you:
accept_ssl_lib="no" ac_check_lib(ssl, openssl_init_ssl, [accept_ssl_lib="yes"]) ac_check_lib(ssl, ssl_library_init, [accept_ssl_lib="yes"]) as_if([test "x$accept_ssl_lib" = xno], [ac_msg_error([library 'ssl' required openssl])]) you may need variable tell init function call, set ssl, unless there's macro magic in header file fix right value.
