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.

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.

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've deleted that example from the Wiki. Look at src/modules/rlm_example/Makefile. It works, and is correct. Edit it to build your module. It's a *lot* simpler.

Re: Linking Shared/Static library in Freeradius Module
I have followed the steps here : http://wiki.freeradius.org/Modules2#Testing The makefile is almost the same with the makefile there. It is recommended to use your own make file in the wiki entry My module works fine without linking libraries. The problems arise when i try to link external libraries.

You didn't follow the FreeRADIUS build process. makefile of the freeradius module : /VERS = 2.1.10 CFLAGS = -DNDEBUG -Wall -I/usr/include \ -I/usr/ports/net/freeradius2/work/freeradius-server-$(VERS)/src LIBS= -lc -L. icc-wrapper.a ALL:rlm_itap.o rlm_itap-$(VERS).so/ Uh... *why* did you do this? The server ships with *many* examples of building modules. The build system for the server takes care of all of the necessary magic to make it Just Work. By creating your own Makefile you've done more work than necessary, and ensured that the resulting module won't work with FreeRADIUS. Alan DeKok. - List info/subscribe/unsubscribe?
