Subject [users@httpd] Apache 2.0.54 compile error with mod_auth_ldap on Solaris 8 -- an d workaround file hack
Date Mon, 08 Aug 2005 20:50:19 GMT
I've been trying to build 2.0.54 (and other recent versions) under Solaris
2.8 with mod_auth_ldap using these configure options:

./configure --prefix=/app/www/apache2 --with-ldap --enable-ldap
--enable-auth-ldap

I have OpenLDAP 2.2.26 built and installed under /usr/local, using gcc
2.95.3 for all of this.

The apache build failed with this compile error in the server directory for
exports.c:

/export/home/app/www/httpd-2.0.54/srclib/apr/libtool --silent --mode=compile
gcc  -g -O2 -pthreads    -DSOLARIS2=8 -D_POSIX_PTHREAD_SEMANTICS
-D_REENTRANT -DAP_HAVE_DESIGNATED_INITIALIZER

-c exports.c && touch exports.lo
In file included from exports.c:39:
/export/home/app/www/httpd-2.0.54/include/util_ldap.h:72: `LDAP_DEREF_NEVER'
undeclared here (not in a function)
<more errors follow>

Digging into this, I found that include/util_ldap.h includes
srclib/apr-util/include/apr_ldap.h. That file has a section that should
include the appropriate header files, but these were not filled in properly
by configure. So edited apr_ldap.h by hand like so:

#if APR_HAS_OPENLDAP_LDAPSDK


#endif

Changed to

#if APR_HAS_OPENLDAP_LDAPSDK
#include <lber.h>
#include <ldap.h>
#endif

And the build went fine! (But have not verified that mod_auth_ldap works OK
yet).

Just thought I'd post this in case others are running into this issue. I'm
not sure what the true fix is though. Somehow this macro substitution in
apr_ldap.h.in is not being done properly by configure, but this is all a
mystery to me:

#if APR_HAS_OPENLDAP_LDAPSDK
@lber_h@
@ldap_h@
#endif

If you think this should be posted elsewhere or submitted as a bug, let me
know!
