There's one thing I don't entirely understand about the GMP problem.
I understand that there are some limitations on GHC's ability to
generate relocatable (and therefore dynamically linkable) code on x86
(a register allocation problem related to the mangler if I recall the
comments in the code correctly). But this shouldn't prohibit linking
GMP in dynamically, should it? It's just a C library and GCC should
happily generate relocatable code. As a dynamically linked library,
there should be no tainting issues to worry about even if the
dynamically linked code is shipped with the executable.
Am I missing something?
No, the LGPL doesn't mandate source redistribution when you redistribute
a binary that is dynamically linked to a LGPL-licensed library. If GHC
did support dynamically linking programs, it wouldn't be an issue, but
GHC only supports that on OS X.
I was wondering something similar - is it really easier to replace the
functionality and speed of GMP than to extend GHC's dynamic library
support to other platforms?
