Netbeans: optional language package is not install

CompilersIf you are using netbeans to develop c/c++ program, it has 3 kind compilers availabe to us. 1. Sun UCB Compatible C Compiler.    Make command,/usr/ccs/bin/make    C compiler,/usr/ucb/cc   2. GNU Compiler Collection     Make command,/usr/sfw/bin/gmake   C Compiler,/usr/sfw/bin/gcc   C++ Compilter,/usr/sfw/bin/g++3. Sun Studio 12 Compiler Collection    Make command,/opt/SUMWspro/bin/dmake   C Compiler,/opt/SUMWspro/bin/cc   C++ Compilter,/opt/SUMWspro/bin/CCFor the item #1, Sun provides neither a C nor a C++ compiler with Solaris[TM] 9 and earlier. The/usr/ucb/cc script you are executing is not a real compiler, but the interface to the BSD Compatibility Package C compiler. It is a script that looks for the/usr/ccs/bin/ucbcc link to the acc driver of Sun's C compiler, and ultimately it calls Sun's C compiler with the/usr/ucb includes and libraries. Never use/usr/ucb/cc except if you want to compile for the obsoleted BSD compatibility.So if you really want to use/opt/ucb/cc to compile the program, you need to make a link

ln -s /opt/SUMWspro/bin/cc /usr/ccs/bin/ucbcc

Then it works like 
/usr/ucb/cc --> /usr/ccs/bin/ucbcc -> /opt/SUMWspro/bin/cc



For the difference between Sun Studio and GCC compilers, please refer to

Configuration

1. Go to tools --> options. 
2. In the memo of Current Path, add the root dir of your compilers. 
   1). /usr/bin:/usr/sbin
   2). /usr/ucb
   3). /usr/sfw/bin
   4). /opt/SUMWspro/bin
3. The compilers will be identified automatically.
