When I try to compile Apache 2.4.23 with OpenSSL 1.1.0b I get: secure:httpd-2.4.23 administrator$ sudo make <--many lines cut out--> /Users/administrator/Downloads/httpd-2.4.23/srclib/apr/libtool --silent --mode=link gcc -arch x86_64 -L/usr/local/openssl/lib -lssl -lcrypto -lpthread \ -o ab ab.lo /Users/administrator/Downloads/httpd-2.4.23/srclib/apr-util/libaprutil-1.la -lexpat -liconv /Users/administrator/Downloads/httpd-2.4.23/srclib/apr/libapr-1.la -lpthread Undefined symbols for architecture x86_64: "_CRYPTO_malloc_init", referenced from: _main in ab.o "_SSLv2_client_method", referenced from: _main in ab.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make[2]: *** [ab] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all-recursive] Error 1 It compiles fine with 1.0.1j, but I am curious what I need to change to get 1.1.0b working? (this may be for the httpd mailing list, but since it was specific to v1.1.0 I thought I would start here. OS is Mac OS X 10.11.6. Thank you, Brian
