libidn.so: No such file or directory

PROBLEM
libidn.so: No such file or directory

ENVIRONMENT

• On-Premise Server + WebMail Installations: Version 6.0 > Current Version

CAUSE
ClamAV configuration.

RESOLUTION

1. Under a fresh installation of RedHat Fedora Core3 ( FC3 ) , a compile of the Clam/Atmail Anti-virus daemon can fail with the following:

   gcc: /usr/lib/libidn.so: No such file or directory
   make[2]: *** [libclamav.la] Error 1
   make[2]: Leaving directory `/usr/local/atmail/webmail/libs/src/clamav/libclamav'
   make[1]: *** [all-recursive] Error 1
   make[1]: Leaving directory

2. Basically this is an error with the library pathname. To solve, just create a symbolic link with the following:
   

   root# ln -s /usr/lib/libidn.so.11.4.6 /usr/lib/libidn.so

   Next, recompile and the ClamAV installation will be successful.
