I am running on CentOS 5.2 on an x86_64 architecture. I note a previous report for a similar system here on the list, but this is not the same error. That one was an error compiling radmin, this is an error compiling the server: gcc -g -O2 -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall -D_GNU_SOURCE -DNDEBUG -I/local/src/freeradius-server-2.1.0/src -DHOSTINFO= \"x86_64-unknown-linux-gnu\" -DRADIUSD_VERSION=\"2.1.0\" -DOPENSSL_NO_KRB5 -c listen.c -fPIC -DPIC -o .libs/listen.o listen.c: In function 'client_listener_find': listen.c:189: warning: assignment discards qualifiers from pointer target type In file included from command.c:26, from listen.c:1046: /local/src/freeradius-server-2.1.0/src/freeradius-devel/modpriv.h:9:18: error: ltdl.h: No such file or directory In file included from command.c:26, from listen.c:1046: /local/src/freeradius-server-2.1.0/src/freeradius-devel/modpriv.h: At top level: /local/src/freeradius-server-2.1.0/src/freeradius-devel/modpriv.h:30: error: expected specifier-qualifier-list before 'lt_dlhandle' gmake[4]: *** [listen.lo] Error 1 gmake[4]: Leaving directory `/local/src/freeradius-server-2.1.0/src/main' gmake[3]: *** [common] Error 2 gmake[3]: Leaving directory `/local/src/freeradius-server-2.1.0/src' gmake[2]: *** [all] Error 2 gmake[2]: Leaving directory `/local/src/freeradius-server-2.1.0/src' gmake[1]: *** [common] Error 2 gmake[1]: Leaving directory `/local/src/freeradius-server-2.1.0' make: *** [all] Error 2 I realize this isn't a complete enough report to fully debug this, I'm just curious to know if anyone else has seen this one or whether it's something obvious. I also know that the ltdl.h file is actually there in the libltdl subdirectory, so I can probably figure out how to get around this if I have to. --Greg
