I installed freeradius 2.1.12 to my ubuntu machine:
apt-get install freeradius
Then I downloaded its source,
apt-get source freeradius
build the source:
cd freeradius-2.1.12+dfsg
./configure --prefix=/root/freeradius/freeradius-2.1.12
make
make fails:
/root/freeradius-2.1.12+dfsg/src/lib/libfreeradius-radius.la -lnsl -lresolv -lpthread -lssl -lcrypto
gcc -shared .libs/eapcommon.o .libs/eapcrypto.o .libs/eapsimlib.o .libs/fips186prf.o -Wl,--rpath -Wl,/root/freeradius-2.1.12+dfsg/src/lib/.libs -Wl,--rpath -Wl,/root/freeradius/freeradius-2.1.12/lib /root/freeradius-2.1.12+dfsg/src/lib/.libs/libfreeradius-radius.so -lnsl -lresolv -lpthread -lssl -lcrypto -Wl,-soname -Wl,libfreeradius-eap-2.1.12.so -o .libs/libfreeradius-eap-2.1.12.so
/usr/bin/ld: cannot find -lssl
/usr/bin/ld: cannot find -lcrypto
collect2: error: ld returned 1 exit status
Then I wonder how come "apt-get install" can work, so I checked:
#type freeradius
freeradius is hashed (/usr/sbin/freeradius)
# ldd /usr/sbin/freeradius
libfreeradius-radius-2.1.12.so => /usr/lib/freeradius/libfreeradius-radius-2.1.12.so (0x00007f3d6d1df000)
libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007f3d6c735000)
So libcrypto and libssl both exist at /lib/x86_64-linux-gnu.
Then how can I instruct configure to take /lib/x86_64-linux-gnu?
