Re: Linking Shared/Static library in Freeradius Module
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:

Re: Linking Shared/Static library in Freeradius Module
Well, yes it seems to be problem. But there is one more thing. The libprint.so should reside in : /usr/lib or /usr/local/lib/ Considering my experience with writing a module for freeradius i think wiki page for module creation can be updated with following info: 1) Mentioning autoconf procedure. autoconf.in makefile.in files. running autoconf running ./configure building: gmake clean gmake gmake install Regards On 12/08/2011 04:58 PM, Fajar A.

No. Autoconf is insane and complicated. There is no reason why normal people need to use it. I use it, and look how I turned out... For building modules, it should be VERY easy. See the examples in rlm_example. Change the names, add header files and libraries. That's it. Many other people have done this, and it works. Alan DeKok. - List info/subscribe/unsubscribe?

Re: Linking Shared/Static library in Freeradius Module
I am trying to use src/modules/rlm_example/Makefile using configure files. In this makefile stated : # The RLM_LIBS definition should list ALL required libraries. # These libraries really should be pulled from the 'config.mak' # definitions, if at all possible. These definitions are also # echoed into another file in ../lib, where they're picked up by # ../main/Makefile for building the version of the server with # statically linked modules. Get it from autoconf. # Which file mentioned with These definitions are also # echoed into another file in ../lib, ? 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. 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.

Linking Shared/Static library in Freeradius Module
Hello, I am writing a FreeRadius (Version 2) module for version Freeradius 2.1.10 . The module works fine. When i want to link a shared/static library from the Makefile of the module i get errors.
