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

From UNIXguide.net:
http://www.unixguide.net/sun/faq/5.36.shtml:


There is no C compiler included in Solaris 2.x. The /usr/ucb/cc script you are executing is a wrapper for the SunSoft C compiler which calls the native C compiler with the /usr/ucb includes and libraries. You need to get yourself a C compiler. Alternatively, you may have forgotten to put the proper link from /usr/ccs/bin/ucbcc to /opt/SUNWspro/SCxxxx/cc in place.

Verify the following packages are installed with pkginfo:
SUNWscpu
SUNWbtool
SPROcc (unbundled SPARCworks Professional C compiler)

The SPROcc package is likely not installed, and is not delivered with the operating system.

More information:
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.

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

Invoke usr/ucb/cc to verify this worked.
