My question is more focused on the "Require.private" change, especially
concerning linking. As I understand it, packagers are invited to change
"Require" into "Require.private" to avoid linking programs against
libraries they do not directly depend on (leaving the job to the dynamic
linker). cairo, for example, started to do this. there is also a word
about this in
Is it really the new "official" way?
If yes, it would imply changing a huge number of packages; and I do
not see the real benefit of it, since it could have been handled with "Require"
by simply omitting the "-l" flags in dependencies when building dynamic code.
"Require" becomes apparently useless.
Am I missing something?
