Name: mmake -- Mercury Make
Usage: mmake [<mmake options>] [-- <make options>] <target>...
Options:
--use-mmc-make:
Use \`mmc --make' to build Mercury targets.
Implies \`--use-subdirs'.
--use-subdirs:
Build intermediate files in a \`Mercury' subdirectory,
rather than in the current directory.
(If the current directory already contains a \`Mercury'
subdirectory, then this option is the default.)
--target c:
Compile via C, rather than going directly to assembler.
This is the default."
Help="$Help
--mercury-standard-library-directory <directory>
--mercury-stdlib-dir <directory>:
The directory containing the installed Mercury standard
library.
--no-mercury-standard-library-directory, --no-mercury-stdlib-dir:
Don't use an installed Mercury standard library.
-s, --save-makefile:
Save the generated makefile to \`Mmake.makefile'.
This is useful for tracking down syntax errors in
your Mmake file.
-f <filename>, --file <filename>:
Use the specified file as the Mmake file.
-v, --verbose:
Print verbose progress messages.
-w-, --no-warn-undefined-vars:
Normally Mmake will warn about variables which are used
but not defined. This option disables that warning.
(The warning is never enabled when doing \`mmake clean'
or \`mmake depend' or the like, to avoid spurious
warnings when the dependencies have not yet been made.)
-h, --help:
Print this usage message.
Targets:
<module>.depend:
Make the files \`<module>.dep' and \`<module>.dv'.
This step is required in preparation for the targets below.
<module>:
Compile and link a Mercury program with main module
\`<module>.m' to produce an executable.
clean:
Remove intermediate files.
realclean:
Remove all automatically-generated files: intermediate files,
dependency files, and executables.
