Recently I received an email with a question regarding the licensing of a module I've written and uploaded to Hackage. I released it under LGPL. The sender wondered if I would consider re-licensing the code under BSD (or something similar) that would remove the need for users to provide linkable object files so that users can re-link programs against newer/modified versions of my library.
Since GHC does cross-package inlining, code of your library is directly included (not just linked) into code that uses the library. So I think that every code that uses your library will have to be released und the GPL or LGPL which is a very bad situation.
People, don’t release Haskell libraries under the LGPL!
That would be serious indeed, but before changing my ways I'd need more information to back up your statement. Could someone confirm that code from one installed module can be inlined into another? AFAIU you are saying that the linker is reaching into the module's .a file, pulling out the .o file, and then reaching into that .o file to pull out an individual function's ASM code. I believe that's a bit more than regular C linkers would do. /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus Haskell is an even 'redder' pill than Lisp or Scheme. -- PaulPotts
