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.
