ignore_action -- A build check method that ignores changes in the command.
build_check ignore_action
The ignore_action method is exactly like the exact_match method except that it will not cause a rebuild if the command string changes. This method is intended to be used (along with the variable $(changed_inputs)) for commands that update an output file rather than remake it from scratch. For example,
ignore_action
exact_match
libxyz.a : *.o : build_check ignore_action ar ru $(output) $(changed_inputs)
is one way that you can update an archive. (There are a number of reasons why updating an archive can lead to incorrect builds, however. See the makepp cookbook for details.)
To install Mpp, copy and paste the appropriate command in to your terminal.
cpanm
cpanm Mpp
