You can simplify complicated compiler commands by defining special shell aliases, using the CCFLAGS environment variable, or by using make.
The following example defines an alias for a command with frequently used options.
example% alias CCfx "CC -fast -xnolibmil"
The next example uses the alias CCfx.
example% CCfx any.C
The command CCfx is now the same as:
example% CC -fast -xnolibmil any.C
You can specify options by setting the CCFLAGS variable.
The CCFLAGS variable can be used explicitly in the command line. The following example shows how to set CCFLAGS (C Shell):
example% setenv CCFLAGS ’-xO2 -m64’
The next example uses CCFLAGS explicitly.
example% CC $CCFLAGS any.cc
When you use make, if the CCFLAGS variable is set as in the preceding example and the makefile’s compilation rules are implicit, then invoking make will result in a compilation equivalent to:
CC -xO2 -m64 files...
The make utility is a very powerful program development tool that you can easily use with all Solaris Studio compilers. See the make(1S) man page for additional information.
When you are using the implicit compilation rules of the makefile (that is, there is no C++ compile line), the make program uses CCFLAGS automatically.
