RE: Dependencies between "build" and "dist"

[Woolley, Robert]

My use of cons is mostly "Cargo-Cult" programming, so maybe someone can
correct me if I am wrong.

Isn't there a trivial workaround here of having  a script that echoes a
dummy target file, and runs pkgmk as a side effect.

The issue for Arun is that pkgmk in solaris creates a directory as its
final output. This is particularly irritating in the cons view of the world
since we expect file targets for dependency checking. I had a conversation
with Bob previously on this very same issue, and there was no good way to
make cons (make .. cons) depend on a directory (or create a directory as its
target.)
