      yum install jbcs-httpd24-httpd-devel

      yum install jbcs-httpd24-httpd-devel

      1) Install apr and apr-util:

      $ yum install apr apr-util -y

      2) Install jbcs-httpd24-httpd:

      $ yum install jbcs-httpd24-httpd -y

      3) Try to start the service (this is rhel-6 output, but the problem affects rhel-7 too it just manifests a bit differently):

      Starting httpd: /opt/rh/jbcs-httpd24/root/usr/sbin/httpd: symbol lookup error: /opt/rh/jbcs-httpd24/root/usr/sbin/httpd: undefined symbol: apr_crypto_init
                                                           [FAILED]

      4) (Optional) You can verify that the linkages in the httpd binary are incorrect with ldd:

      # ldd /opt/rh/jbcs-httpd24/root/usr/sbin/httpd | grep apr
	libaprutil-1.so.0 => /lib64/libaprutil-1.so.0 (0x00007fa5b5147000)
	libapr-1.so.0 => /lib64/libapr-1.so.0 (0x00007fa5b492f000)

      The ldd output should look like this:

      # ldd /opt/rh/jbcs-httpd24/root/usr/sbin/httpd | grep apr
	libaprutil-1.so.0 => /opt/rh/jbcs-httpd24/root/usr/lib64/libaprutil-1.so.0 (0x00007fe11191d000)
	libapr-1.so.0 => /opt/rh/jbcs-httpd24/root/usr/lib64/libapr-1.so.0 (0x00007fe111100000)
      Show
      1) Install apr and apr-util: $ yum install apr apr-util -y 2) Install jbcs-httpd24-httpd: $ yum install jbcs-httpd24-httpd -y 3) Try to start the service (this is rhel-6 output, but the problem affects rhel-7 too it just manifests a bit differently): Starting httpd: /opt/rh/jbcs-httpd24/root/usr/sbin/httpd: symbol lookup error: /opt/rh/jbcs-httpd24/root/usr/sbin/httpd: undefined symbol: apr_crypto_init [FAILED] 4) (Optional) You can verify that the linkages in the httpd binary are incorrect with ldd: # ldd /opt/rh/jbcs-httpd24/root/usr/sbin/httpd | grep apr libaprutil-1.so.0 => /lib64/libaprutil-1.so.0 (0x00007fa5b5147000) libapr-1.so.0 => /lib64/libapr-1.so.0 (0x00007fa5b492f000) The ldd output should look like this: # ldd /opt/rh/jbcs-httpd24/root/usr/sbin/httpd | grep apr libaprutil-1.so.0 => /opt/rh/jbcs-httpd24/root/usr/lib64/libaprutil-1.so.0 (0x00007fe11191d000) libapr-1.so.0 => /opt/rh/jbcs-httpd24/root/usr/lib64/libapr-1.so.0 (0x00007fe111100000)

      The httpd service will not start if a user installs JBCS httpd on a system that already has apr and apr-util.
