Hello, I will try to explain what i am trying to achive. I am developing a freeradius module called rlm_itap. This module uses a shared library called print.so (a library i use for test purposes.). There is only one procedure in the library and it is called : myprint() . I am able to run freeradius server with my own module : $ radiusd -X I send a test message with $ radtest testuser "pass" localhost 0 testing123 If i do not use myprint() function in my own module everything works fine and i am able to receive the incomming message: +- entering group authorize {...} ++[preprocess] returns ok ITAP: Received auth message =>*My own debug msg* But when i use the method myprint() from the library print.so , i get the error when i run the server and send a message with radtest : /# Executing section authorize from file /usr/local/etc/raddb/sites-enabled/default +- entering group authorize {...} ++[preprocess] returns ok ITAP: Received auth message /libexec/ld-elf.so.1: /usr/local/lib/freeradius-2.1.10/rlm_itap-2.1.10.so: *Undefined symbol "myprint"*/ So this is the problem i am having. After your email i started to use autoconf and it is easier than writing my own makefile. But i am still not able to resolve this problem. As far as i understand freeradius is not able to see find print.so library. I have to find a way to show the server this library.... I prepare my module as : $ autoconf $ ./configure $ gmake clean $ gmake $ gmake install Here is some more information and my makefiles: *$ gmake * [root@vm1 /usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src/modules/rlm_itap]# gmake for x in .libs/* rlm_itap.la; do \ rm -rf /usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src/modules/lib/$x; \ ln -s /usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src/modules/rlm_itap/$x /usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src/modules/lib/$x; \ done [root@vm1 /usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src/modules/rlm_itap]# gmake clean [root@vm1 /usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src/modules/rlm_itap]# gmake /usr/local/bin/libtool --mode=compile cc -O2 -pipe -I/usr/local/include -L/usr/local/lib -DHAVE_LT_DLADVISE_INIT -DHAVE_LT_DLADVISE_INIT -fno-strict-aliasing -pthread -Wall -D_GNU_SOURCE -DNDEBUG -I/usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src -I/usr/include -I/home/resit/radius/include/ -c rlm_itap.c libtool: compile: cc -O2 -pipe -I/usr/local/include -L/usr/local/lib -DHAVE_LT_DLADVISE_INIT -DHAVE_LT_DLADVISE_INIT -fno-strict-aliasing -pthread -Wall -D_GNU_SOURCE -DNDEBUG -I/usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src -I/usr/include -I/home/resit/radius/include/ -c rlm_itap.c -fPIC -DPIC -o .libs/rlm_itap.o libtool: compile: cc -O2 -pipe -I/usr/local/include -L/usr/local/lib -DHAVE_LT_DLADVISE_INIT -DHAVE_LT_DLADVISE_INIT -fno-strict-aliasing -pthread -Wall -D_GNU_SOURCE -DNDEBUG -I/usr/ports/net/freeradius2/work/freeradius-server-2.1.10/src -I/usr/include -I/home/resit/radius/include/ -c rlm_itap.c -o rlm_itap.o

Which file mentioned with "These definitions are also # echoed into another file in ../lib," ? Files automatically produced by the builds.

I could not find this file. As far as i understand, i have to add shared/static libraries ( which i link from my new module ) into this file . So freeradius can find them. No. You just add them in the RLM_LIBS line.

...

I consider this because i get the error :

/libexec/ld-elf.so.1: /usr/local/lib/freeradius-2.1.10/rlm_itap-2.1.10.so: Undefined symbol "sendiccmsg"

when i run radiusserver and send an autorization message to server. You probably need to re-build radiusd, too.

Or... *show* what you did. This isn't hard.

The current build process *can* link to static libraries, and *does* link to static libraries, and *works* when modules are linked to static libraries. If you follow the examples, it *should* work.
