[julia-users] Re: Error precompiling on Windows 64 (julia 0.4.0 and 0.4.6)

['Bill Hart' via julia-users]

I've narrowed it down to an issue in the following snippet of code which is 
in __init__ in our package:

   ccall((:__gmp_set_memory_functions, libgmp), Void,
      (Ptr{Void},Ptr{Void},Ptr{Void}),
      cglobal(:jl_gc_counted_malloc),
      cglobal(:jl_gc_counted_realloc_with_old_size),
      cglobal(:jl_gc_counted_free))

Can anyone see what could possibly be wrong with this? It works just fine 
on Linux, but not Windows 64.

Note, we define libgmp as follows (which I am sure is correct):

const pkgdir = realpath(joinpath(dirname(@__FILE__), ".."))
const libdir = joinpath(pkgdir, "local", "lib")
const libgmp = joinpath(pkgdir, "local", "lib", "libgmp")

Bill.
