Using CCFLAGS to Specify Compile Options

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):

 demo% setenv CCFLAGS '-silent -fast -Xlist'

The next example uses CCFLAGS explicitly.

 demo% 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 -silent -fast -Xlist files...
