Re: [gentoo-portage-dev] RFC: Binary dependency tracking

[Jeremy Huddleston]

Well, I've glossed over the dlopen() issues for now as I'm not sure the
best way to handle that or even if it needs to be addressed.  How often
does something dlopen() a file if it doesn't know the exact filename at
compile time?  It seems unlikely to me that this kind of dependency
would be introduced which wouldn't be uniquely satisfied by the RDEPEND.
Does anyone know of a case where we'd do something like:

#define LIBPNG_SONAME libpng.so.3 /* set by configure */
dlopen(LIBPNG_SONAME)


In any event, here's a patch to portage which creates the
soname.{PROVIDE,DEPEND} files as well as a small script to create them
where missing.

Please comment.

Thanks,
Jeremy
