The Fortran code I'm working with assigns results to a number of global
variables. One of those results is a 3x1 real array - let's call it v1.
I'm trying to understand how to access this. Here's what I have:
v1 = cglobal((:__libkl_mod_MOD_v1,"libkl.so"),Ptr{Float64})
This gives me a Ptr{Ptr{Float64}}. I'm not sure what to do from here --
using pointer_to_array just gives
julia> pointer_to_array(v1,3)
3-element Array{Ptr{Float64},1}:
Ptr{Float64} @0x0000000000000000
Ptr{Float64} @0x0000000000000000
Ptr{Float64} @0x0000000000000000
And then doing an unsafe_load on any of those elements gives me a segfault.
Am I taking the right approach here? The Fortran code is not my own, so
it's possible this is due to an error in that code, but I'm trying to rule
out Julia interface issues first.
Thanks in advance,
Chris
