Yep....I did

I restarted from scratch

./configure yields then

configure: error: FreeRADIUS requires libtalloc

OK it needs talloc stuff

./configure
--with-talloc-include-dir=~/leaf/devel/master-new-openssl/staging/x86_64-unknown-linux-uclibc/usr/include/samba
 --with-talloc-lib-dir=~/leaf/devel/master-new-openssl/staging/x86_64-unknown-linux-uclibc/usr/lib

configure: error: FreeRADIUS requires libtalloc

despite

ls
~/leaf/devel/master-new-openssl/staging/x86_64-unknown-linux-uclibc/usr/lib/libtalloc*
/home/mega/leaf/devel/master-new-openssl/staging/x86_64-unknown-linux-uclibc/usr/lib/libtalloc.so
/home/mega/leaf/devel/master-new-openssl/staging/x86_64-unknown-linux-uclibc/usr/lib/libtalloc.so.2
/home/mega/leaf/devel/master-new-openssl/staging/x86_64-unknown-linux-uclibc/usr/lib/libtalloc.so.2.0.5

So obviously there are talloc libraries present there.

This error does not show up when I use the whole shebang of
configuration options

Now I commented out the offending macros and ran

mega at leafbuilder:~/leaf/devel/master-new-openssl/source/x86_64-unknown-linux-uclibc/radius/freeradius-server-3.0.21$
make reconfig
Makefile:38: *** Missing 'Make.inc' Run './configure [options]' and
retry.  Stop.

OK so rerunning configure yields

checking for __builtin_choose_expr support in compiler... configure:
error: in
`/home/mega/leaf/devel/master-new-openssl/source/x86_64-unknown-linux-uclibc/radius/freeradius-server-3.0.21':
configure: error: cannot run test program while cross compiling
See `config.log' for more details

Obviously the modified configure.ac did not build a new configure
script. Using autogen.sh before did.

There must be a proper way to rebuild configure here.

Thanks
