I just downloaded 3.0.4rc2 to check it on a development box I recently had built for me. It seems the configure script isn't checking to make sure pcre development libs are installed. This was on a RHEL 6.5 64bit box. .... CC src/lib/heap.c CC src/lib/tcp.c CC src/lib/base64.c CC src/lib/version.c /usr/bin/ld: cannot find -lpcre collect2: ld returned 1 exit status make: *** [build/lib/local/libfreeradius-radius.la] Error 1 ... yum install pcre-devel Then afterwards .... CC src/lib/heap.c CC src/lib/tcp.c CC src/lib/base64.c CC src/lib/version.c LINK build/lib/libfreeradius-radius.la CC src/tests/rbmonkey.c LINK build/bin/rbmonkey ... Might be worth adding a check in to make sure the development libs are available. Cheers Peter
