Apache not linked correctly to OpenSSL

Question

I have downloaded the httpd-2.4.20 source files and tried to build it using the OpenSSL already installed on the system, which is Openssl 1.0.1t.
I used these commands in order to achieve the desired result:

$ CFLAGS='-DSSL_EXPERIMENTAL_ENGINE' ./configure --with-ssl=/usr/local/ssl $ --with-pcre=/usr/local/pcre --enable-ssl --enable-so $ make # make install 

My intention is to make Apache, via mod_ssl, be able to use some OpenSSL engines specified in the openssl.cnf file. But if I type ldd httpd the results do not list the OpenSSL libraries: libcrypto.so.1.0.0 and 'libssl.so.1.0.0, but instead:

# ldd httpd linux-vdso.so.1 => (0x00007ffc86eb7000) libpcre.so.1 => /usr/local/pcre/lib/libpcre.so.1 (0x00007f9ff8543000) libaprutil-1.so.0 => /usr/local/apache2/lib/libaprutil-1.so.0 (0x00007f9ff830f000) libapr-1.so.0 => /usr/local/apache2/lib/libapr-1.so.0 (0x00007f9ff80d3000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f9ff7e99000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9ff7ad3000) libexpat.so.0 => /usr/local/apache2/lib/libexpat.so.0 (0x00007f9ff78a0000) libcrypt.so.1 => /lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007f9ff7667000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f9ff7462000) /lib64/ld-linux-x86-64.so.2 (0x000055cbf518d000) 

Since I have explicitly specified --with-ssl=/usr/local/ssl, which is the installation directory of OpenSSL, why I am not able to use its libraries?

Answer 1

Why do you compile apache on your own instead of using the package that is provided by your vendor (distribution)?

If you compile on your own you have issues like this and security updates also requires repeated efforts.
