Problem: I am trying to compile the Apache web server using the latest sources of httpd, apr and apr-util, and enabling LDAP support. My current steps do not seem to be commpiling mod_ldap.so and mod_authnz_ldap.so.
Environment background: Build and target OS are RHEL5. A non-LDAP enabled instance of httpd is already on the server (2.4.1) and SVN 1.7.3 is already installed and works anonymously with httpd-2.4.1
Steps to reproduce: Following the compilation instructions here I have downloaded:
- httpd-2.4.4 in /path/apache/src/httpd-2.4.4
- apr 1.4.6 in /path/apache/src/apr-1.4.6
- apr-utils 1.5.2 /path/apache/src/apr-util-1.5.2
- OpenLDAP and Berkley DB (for the LDAP libraries to build apr-util against) in /path/openldap-2.4.35_src and /path/db-5.3.21_src
With the sources in place, I: compiled BDB and installed it to /path/db-5.3.21 compiled OpenLDAP using the installed BDB and installed it in /path/openldap-2.4.35 configured apr, compiled and installed it in /path/apache/apr configured apr-util with:
./configure --with-ldap --prefix=/path/apache/apr-util-1.5.2 --with-apr=/path/apache/apr-1.4.6 --with-ldap-lib=/path/openldap-2.4.35/lib --with-ldap-include=/path/openldap-2.4.35/include
Afterwards, I built and installed with make and make install.
Finally, I configured httpd with the following:
./configure --prefix=/path/apache/httpd-2.4.4 --with-apr=/path/apache/apr-1.4.6 --with-apr-util=/path/apache/apr-util-1.5.2 --with-pcre=/path/apache/pcre-8.30 --with-ldap --enable-ldap
This was successful, and I was able to run make and make install
I now have a httpd instance in /path/apache/httpd-2.4.4/. Using /path/httpd-2.4.1/httpd.conf as a model, I matched the existing configuration and loaded modules, adding:
LoadModule mod_ldap modules/mod_ldap.so
LoadModule mod_authnz_ldap modules/mod_authnz_ldap.so
However, if I run apachectl start I get a syntax error:
/path/apache/httpd-2.4.4> ./bin/apachectl start
httpd: Syntax error on line 148 of /path/apache/httpd-2.4.4/conf/httpd.conf: Can't locate API module structure 'mod_ldap' in file /path/apache/httpd-2.4.4/modules/mod_ldap.so: /path/apache/httpd-2.4.4/modules/mod_ldap.so: undefined symbol: mod_ldap
Looking within the httpd-2.4.4/modules directory, the modules mod_ldap.so and mod_authnz.ldap.so are missing. I have tried the above steps without success. I have discovered that within the src/httpd-2.4.4 directory, the files ./modules/aaa/.libs/mod_authnz_ldap.so and ./modules/ldap/.libs/mod_ldap.so exist, but copying those over to httpd-2.4.4/modules does not alleviate the issue.
Can someone assist me in diagnosing the error in my steps? I know I'm missing something, but I have been unable to find it so far. I will also add any other required information if needed.
