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 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?

    why are you installing both the binary build AND then build it from source? – Gerald Schneider Feb 16 '18 at 7:39

When building from source, you must install the development packages. These are usually named <package-name>-dev (Debian) or <package-name>-devel (RPM). Although, these should be listed in the Build-Depends entry.

On Ubuntu, this should be the package libssl-dev, which also provides header files.

Looking at BuildingTutorial - Get the build dependencies

apt-get build-dep freeradius

should fetch the dependencies, and then

debuild -b -uc -us

builds the freeradius package.
