m3build Options

The following command line options are interpreted by m3build:

clean

Specifies that all compiled code is to be removed from the build directory.

-b dir

Use the <dir> configuration and build in the directory named dir. The default build directory is configured into m3build when it is installed. For example,

m3build -b SPARC

will build using the SPARC configuration instead of the default.

-d dir

Change the current directory to dir before doing anything. This option is most useful when you're editing in the src subdirectory; to compile, issue the following command:

m3build -d ..

-S

Generate derived objects regardless of the current directory's name. Normally, if the current working directory is src, m3build will refuse to build derived objects.

-O

Read the m3overrides file if present.

-v

Be verbose, i.e. echo the quake comand before executing it.

-n

Operations that invoke external programs, e.g. the Modula-3 compiler, are processed but the external programs are not executed.

-V

This option causes all the directories in which m3makefiles are read to be echoed to the standard output. It can be helpful in debugging a complex package structure.
