I want to experiment with libfreeradius, but I am having trouble even compiling the main library header. First, the "libradius.h" header uses the "RCSIDH()" macro before including "build.h"[1]. But even with a manual inclusion of "build.h", I get a missing header dependency:
It's not really intended to be built outside of the main server distribution. i.e. it's not a stand-alone library.
Good to know, then I wonder why the development headers are being installed, and why a development package is available for the library in Debian, maybe there are historic reasons. To provide a bit of context, I was looking into replacing the RADIUS client of our Wi-SUN border router for Linux[1]. I suppose that the recommended method is to use radclient then?

If you build the whole server, then it will also build libfreeradius.
$ echo '#include <freeradius/libradius.h>' | gcc -include freeradius/build.h -xc - In file included from /usr/local/include/freeradius/build.h:13, from <command-line>: /usr/local/include/freeradius/autoconf.h:749:10: fatal error: freeradius/automask.h: No such file or directory 749 | #include <freeradius/automask.h> | ^~~~~~~~~~~~~~~~~~~~~~~ compilation terminated.
The "automask.h" header is present in the repo[2], but it does not seem to be installed as part of the library headers with "make install". It is also not present in by distribution's package of the library[3]. I tried with v3.2.5 packaged by Debian, and v3.2.6 compiled from source, am I doing something wrong?
Hmm.. maybe that should be installed?
I have also found a similar issue[4] which states that "autoconf.h" should not be included, and that "missing.h" provides the necessary values. In any case there is a chain of header dependency which currently forces "autoconf.h" to be included so I am not sure how relevant that statement is.
libradius.h > build.h > autoconf.h > automask.h
That might need to be installed, too.
"autoconf.h" is actually installed, but it pulls "automask.h" which is not.
I did not find much documentation or examples for this library, feel free to redirect me to the right resources in case I missed them. I am also a bit confused with the relation between libfreeradius and the freeradius-client project, the latter seems basically abandoned but it is not clear to me what the functional differences are between the 2.
FreeRADIUS is the server, which includes libfreeradius.
freeradius-client is a separate and stand-alone project which implements a simple RADIUS client. It has about 1% of the functionality of FreeRADIUS.
Thank you for the clarification.
