4.3. Single Letter Sequences

Options may also be passed as single letter sequences. All options apart from those which control cleaning phases or the sudo options, have a single letter form which is prefixed by a single - character. Those letters which correspond to phase control options can be combined into into a sequence prefixed by single - character or by -n. In the latter case all options corresponding to the letters of the sequence are disabled.

If the first phase control option encountered on the build script command line is a single letter sequence and the sequence is not prefixed by -n, then all other phase control options are disabled.

The single letter equivalents of the previous two examples are

build -q

and

build -qm

4.3.1. Upper Case Sequences

All phases that correspond to a build process also have an upper-case single letter parameter form. This is equivalent to the single letter form preceded by the corresponding cleaning operation.

For example

build -m

will build the Qtc wrapper libraries using make and

build -M

will clean and then build the Qtc wrapper libraries.
