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:

Libraries have been installed in:
   /usr/local/lib/freeradius-2.1.10

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

  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.
