Usage: $Script [OPTION] <command>
options:
-clean Cleanup before compilation (removes old makefiles)
-kill Cleanup after termination (removes makefiles)
-h | -help Print the usage
A collecting scheduler for fast parallel compilation of large numbers of
object files.
When called with a compilation command it is written into a file in the
directory \$WM_COLLECT_DIR.
When called without a command the files in the \$WM_COLLECT_DIR directory are
combined into a single Makefile which is passed to make to compile all of the
object files efficiently in parallel.
Typical usage for compiling OpenFOAM:
- Ensure all lnInclude directories are up-to-date:
wmakeLnIncludeAll
- Compile all with this scheduler:
wmake -queue
