Apache 2.4.23 undefined reference to CRYPTO_malloc_init?

OpenSSL 1.0.2 and earlier provided CRYPTO_malloc_init:

openssl-1.0.2h$ grep -R CRYPTO_malloc_init *
apps/apps.h:                        do { do_pipe_sig(); CRYPTO_malloc_init(); \
apps/apps.h:                        do { do_pipe_sig(); CRYPTO_malloc_init(); \
crypto/crypto.h:# define CRYPTO_malloc_init()    CRYPTO_set_mem_functions(\
crypto/dh/dhtest.c:    CRYPTO_malloc_init();
crypto/ecdh/ecdhtest.c:    CRYPTO_malloc_init();
...

OpenSSL 1.1.0 and later do not appear to provide CRYPTO_malloc_init:

openssl-1.1.0b$ grep -R CRYPTO_malloc_init *
openssl-1.1.0b$

Also see Apache Issue 60061 - OpenSSL 1.1.0 support.

There is a patch for httpd 2.4.23 in archlinux user repository which deals with differences between different openssl versions. Among other things it modifies ab.c in the following way:

@@ -2465,7 +2499,11 @@ int main(int argc, const char * const argv[])
 #ifdef RSAREF
     R_malloc_init();
 #else
+#if OPENSSL_VERSION_NUMBER < 0x10100000L
     CRYPTO_malloc_init();
+#else
+    OPENSSL_malloc_init();
+#endif
 #endif
     SSL_load_error_strings();
     SSL_library_init();

I applied the whole patch and the build succeeded.

P.S.: when having problems building popular software from source it might be helpful to look at how your distribution biulds the package (find the PKGFILE/specfile/rules, etc.).
