7.15 Using getopt(3C)
There is a template named, ‘getopt.tpl’ that is distributed with
AutoOpts. Using that template instead of ‘options.tpl’ will produce
completely independent source code that will parse command line options. It
will utilize either the standard
getopt(3C) or the GNU
getopt_long(3GNU) function to drive the parsing. Which is used is
selected by the presence or absence of the
long-opts program attribute.
It will save you from being dependent upon the
libopts library and
it produces code ready for internationalization. However, it also carries
with it some limitations on the use of AutoOpts features and some requirements
on the build environment.
PLEASE NOTE: in processing the option definitions to produce
the usage text, it is necessary to compile some generated code in a
temporary directory. That means that all the include directories
needed to compile the code must be full path names and not relative
directory names. “.” is a relative directory name. To specify
“-I.” in the
CFLAGS environment variable, you must expand it.
