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

Cause

When compiling some code for BSD compatibility the error happened after invoking usr/ucb/cc. The unbundled compiler (SPARCworks Professional C product) was installed in /opt.

/usr/ucb/cc is a script which 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 installation of the unbundled C compiler, SPROcc.

Action

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

Solve the problem by creating a new symbolic link:

   # ln -s /opt/SUNWspro/bin/acc /usr/ccs/bin/ucbcc
