   My suspicion is that you've built 2.1.9 with version X of Perl, and are then trying to link it with version Y of Perl.  Ensure that you only have one version of Perl installed. That's not the case here, I have (and had when building 2.1.9 this morning) only following libperl stuff installed:   dpkg -l|grep libperl ii  libperl-dev   5.10.1-8ubuntu2   Perl library: development files ii  libperl5.10   5.10.1-8ubuntu2   shared Perl library  

Isn't there a way to find out the perl version? I thought of "print $1" but this does not work as intended. Best, Jan

Try using

perl -V

Or if you want to check the version of the embedded perl interpreter FR is using: put something like print "perl version: $^V\n"; into myfile, create a perl module referring to it: perl perlversion { module = myfile } and reference it in the instantiate section instantiate { perlversion .. } restart FR and see the version. Or maybe a bit easier, just look at which perl library rlm_perl is linked with: frtest2:~# ldd /usr/lib/freeradius/rlm_perl.so |grep perl libperl.so.5.10 => /usr/lib/libperl.so.5.10 (0x00007fcba8989000) Bjørn

Did you try defining HAVE_LT_DLADVISE_INIT? I believe your problem is not really related to perl, but to libtool. Which is black magic to me... But changing libtool version and/or playing with different options may get you a working rlm_perl module. Bjørn

That did the trick, I just added #defineHAVE_LT_DLADVISE_INIT to src/main/modules.c as Bj??rn suggested and now it works flaw-less-ly :)

Alan, maybe it's time to enabled that bit by default :) -- 2. That which causes joy or happiness.

Hi, Don't really know enough about libraries, but it could be related to a previous issue I had on debian (issue still exists with 2.1.9) Can you try the following: 1) Make sure freeradius is not already running 2) Start freeradius using as follows: "/usr/sbin/freeradius -X" Confirm it fails. 3) Now start it like this: "LD_PRELOAD=/usr/lib/libperl.so.5.10 /usr/sbin/freeradius -X" If the third step works, it is a debian bug. Modify your /etc/init.d/freeradius. Look for: "start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $PROGRAM || ret=$?" Replace with: "LD_PRELOAD=/usr/lib/libperl.so.5.10 start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $PROGRAM || ret=$?"
