[Rake-devel] How to execute before the '.o' => '.f90' tasks?

[Andrew Chen]

Hi,

First time to the list.  Thanks for your good work.

I'm trying to use Rake to compile some FORTRAN and C codes.

I have a task:

  rule '.o' => '.f90' do |t|
    sh "#{$compiler} -c -o #{t.name} #{t.source} -module #{$build_dir}"
  end

But I have another task: generate_code, this task will make some more
.f90 source files.

I want to my generate code task to be executed before my rule '.o'

   Rake::Task[:gen].invoke if Rake::Task.task_defined?('gen')

How to do that?

Thanks
