Yesod: -dump-splices reliability

Question

I'm using ghc parameter -dump-splices to see the static file names generated by Yesod while debugging.

But I have found that sometimes it displays the static files name ( eg: css_bootstrap_css) but most of the times it doesn't show any of the static files.

Am I doing something wrong here?

I'm attaching the dump file here.

Answer 1

Doing this should solve the issue:

touch Settings/StaticFiles.hs

Or even a cabal configure and build seems to work.
