Hi Stefan,
Please see below for what may be relevant code structure. I am happy to
email the actual code off the list if you think that is necessary.
The code which resulted in the problem had three different files.
1. dataTypes.jl (this file defines the Params composite type).
2. paramcombos.jl (there is a baseparams() function in this file, which
creates
an instance of Params type).
3. runsim.jl (the simulate function which gave the error was in this file)
I did not declare any module statements in either dataTypes.jl or
runsim.jl, but did
declare module paramcombos in paramcombos.jl. The relevant structure of the
files:
-------------------------------------------------------------
*## File dataTypes.jl*
type Params
.
.
.
end
-------------------------------------------------------------
*## File paramcombos.jl*
module paramcombos
import Distributions
include("dataTypes.jl")
function baseparams()
... # body of this function
return Params(...)
end
end
-------------------------------------------------------------
*## File runsim.jl*
include("dataTypes.jl")
require("paramcombos.jl")
function simulate(params::Params, rseed::Int)
... # body of this function
end
function main()
basep = paramcombos.baseparams()
simulate(basep, 1)
end
main()
Thanks for looking into this.
