Hello, I am trying to use http://www.packetfence.org/downloads/PacketFence/freeradius/freeradius-2.2.0... to create custom FreeRadius RPMs for RHEL/CentOS 6. The main aim is to add --with-dhcp compile option which is not included in the standard build. The secondary aim is to build using custom ldap libraries, because we are using LTB OpenLDAP RPM packages (http://ltb-project.org/wiki/download#openldap). The libraries as installed by these RPM packages are in /usr/local/openldap/lib64/ and /usr/local/openldap/include/ In the src.rpm I see: BuildRequires: openldap-devel which I can change to: BuildRequires: openldap-ltb-debuginfo but how can I define custom LDAP libraries? Can I use something like: export CPPFLAGS="${CPPFLAGS} -I/usr/local/openldap/include" export LDFLAGS="${LDFLAGS} -L/usr/local/openldap/lib64" ...as we do for building Dovecot, or CXXFLAGS="${CXXFLAGS} -I/usr/local/openldap/include"; export CXXFLAGS LDFLAGS="${LDFLAGS} -L/usr/local/openldap/lib64 -lldap -llber -R/usr/local/openldap/lib64"; export LDFLAGS ...as we do for building PowerDNS? ( We have found the above for other software after significant effort. I hope it'll be easier with FreeRadius! :-) ) Please advise! Thanks, Nick
