It is unfortunate that sun ever shipped /usr/ucb/cc; you would thinkit was compatible with SunOS 4; instead it compatible with some veryold version of 4.2 but it also required the installation of theSunPro (Now Solaris Studio) compilers. These compilers can be downloaded from http://www.oracle.com/technetwork/server-storage/solarisstudio/downloads/index.html under the following license terms (quoted from the above page) Provides perpetual no-cost license for production use and the development of commercial applications. shareimprove this answer

First, you should probably remove /usr/ucb from your PATH as this directory is quite obsolete now. It was meant to ease people migrating from SunOS 4 to Solaris 2 a couple of decades ago but doesn't make much sense these days. Especially this cc commands
which set specific flags to compile BSDish code.

Second, all current Solaris releases comes with a C compiler out of the box but it is located in a directory which might not be in your PATH, /usr/sfw/bin and is named gcc (Gnu compiler).

use

/usr/sfw/bin/gcc

or

[code]PATH=$PATH:/usr/sfw/bin
gcc

Alternatively, you might have already installed (or you can install) the Solaris Studio compiler. In that case, its path would be <installation-dir>/bin/cc (eg: /opt/SUNWspro/bin/cc or /opt/SolarisStudio11/bin/cc etc ...)
