Command make induces error message

/usr/bin/ld: cannot find -lidn
/usr/bin/ld: cannot find -lldap
collect2: ld returned 1 exit status
make[2]: *** [../bin/SomeApp] Error 1
make[1]: *** [CMakeFiles/SomeApp.dir/all] Error 2
make: *** [all] Error 2

However, lgconfig -p | grep idn returns

libidn.so.11 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libidn.so.11
libcidn.so.1 (libc6,x86-64, OS ABI: Linux 2.6.24) => /lib/x86_64-linux-gnu/libcidn.so.1
libcidn.so.1 (libc6, OS ABI: Linux 2.6.24) => /lib/i386-linux-gnu/libcidn.so.1
libcidn.so (libc6,x86-64, OS ABI: Linux 2.6.24) => /usr/lib/x86_64-linux-gnu/libcidn.so

And ldconfig -p | grep ldap returns

libldap_r-2.4.so.2 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libldap_r-2.4.so.2
libldap_r-2.4.so.2 (libc6) => /usr/lib/i386-linux-gnu/libldap_r-2.4.so.2

How I can rid off this linking errors?


The problem was solved through installing dev-versions of those libraries

sudo apt-get install libldap2-dev
sudo apt-get install libidn11-dev
