Solaris Common Messages and Troubleshooting Guide

/usr/ucb/cc: language optional software package not installed


While compiling some code for BSD compatibility, the error occurred after invoking usr/ucb/cc. The unbundled compiler SPARCworks Professional C product was installed in /opt.

/usr/ucb/cc is a script that checks for the file /usr/ccs/bin/ucbcc and, if found, invokes it with appropriate library flags for BSD-compatibility compilation.

/usr/ucb/cc is part of the package SUNWscpu. /usr/ccs/bin/ucbcc is supposed to be a symbolic link to /opt/SUNWspro/bin/acc, which is created during the installation of the unbundled C compiler, SPROcc.


Verify that you have the essential OS-bundled Developer packages, SUNWscpu, SUNWbtool, and the unbundled C compiler, SPROcc. However, in this case, /usr/ccs/bin/ucbcc was missing on the user's system. Evidently, somehow this link was removed.

Solve the problem by creating a new symbolic link:

# ln -s /opt/SUNWspro/bin/acc /usr/ccs/bin/ucbcc
Invoke usr/ucb/cc to verify this remedy worked.

The following commands are used to identify which packages contain the particular components involved:
