Now, resolve-lib can take a big list of libraries with full paths,
and it can solve a big list of spec at once.
Basically, we move most of the parsing of spec paths into resolve-lib.
Since print-package-signature does build a full list of libs, let's solve
it all at once, instead of invoking a costly perl script repeatedly.
Add some caching possibilities for out-of-date. Specifically:
- store libraries for each package under the directory _PORT_LIBS_CACHE
- use the dependency cache _DEPENDS_FILE to avoid recreating dependency
chains, add a new file _DEPENDS_CACHE that will accumulate all dependencies,
and extract these with a simple script extract-dependencies.
Use echo to build libraries lists instead of ls, that's a bit simpler...
Some more clean-up will happen: it's probably simpler to parse libspecs
at once, extract the libraries needed and go fetch the corresponding libraries
just once.
This is not the linker's way of working, but this is the way dependencies
must be handled to find about update issues.
naddy@ agrees, nobody else gives a fuck.
