BuildExecutable throws unhelpul error message when when output is sent to STDERR during compile.

[haberdashPI]

I was just trying to see if it was possible to use this to compile a simple mathematical optimization problem, and found that the example Sudoku solver on the JuMP.jl website does not compile. The error reported is a problem with not be able to find the STDERR variable. I've checked and this runs when I just call main from julia.

I'm using Julia version 0.4.5, and BuildExecutable version 0.0.3.

Here is my attempt:

import JuMP

function main()
# Create a model
sudoku = JuMP.Model()

# Create our variables
@JuMP.defVar(sudoku, x[i=1:9, j=1:9, k=1:9], Bin)

for i = 1:9, j = 1:9  # Each row and each column
  # Sum across all the possible digits
  # One and only one of the digits can be in this cell, 
  # so the sum must be equal to one
  @JuMP.addConstraint(sudoku, sum{x[i,j,k],k=1:9} == 1)
end

for ind = 1:9  # Each row, OR each column
  for k = 1:9  # Each digit
      # Sum across columns (j) - row constraint
      @JuMP.addConstraint(sudoku, sum{x[ind,j,k],j=1:9} == 1)
      # Sum across rows (i) - column constraint
      @JuMP.addConstraint(sudoku, sum{x[i,ind,k],i=1:9} == 1)
  end
end

for i = 1:3:7, j = 1:3:7, k = 1:9
  # i is the top left row, j is the top left column
  # We'll sum from i to i+2, e.g. i=4, r=4, 5, 6
  @JuMP.addConstraint(sudoku, sum{x[r,c,k], r=i:i+2, c=j:j+2} == 1)
end

init_sol = [ 5 3 0 0 7 0 0 0 0;
           6 0 0 1 9 5 0 0 0;
           0 9 8 0 0 0 0 6 0;
           8 0 0 0 6 0 0 0 3;
           4 0 0 8 0 3 0 0 1;
           7 0 0 0 2 0 0 0 6;
           0 6 0 0 0 0 2 8 0;
           0 0 0 4 1 9 0 0 5;
           0 0 0 0 8 0 0 7 9]
for i = 1:9, j = 1:9
    # If the space isn't empty
    if init_sol[i,j] != 0
        # Then the corresponding variable for that digit
        # and location must be 1
        @JuMP.addConstraint(sudoku, x[i,j,init_sol[i,j]] == 1)
    end
end

JuMP.solve(sudoku)

# Extract the values of x
x_val = JuMP.getValue(x)
# Create a matrix to store the solution
sol = zeros(Int,9,9)  # 9x9 matrix of integers
for i in 1:9, j in 1:9, k in 1:9
    # Integer programs are solved as a series of linear programs
    # so the values might not be precisely 0 and 1. We can just
    # round them to the nearest integer to make it easier
    if iround(x_val[i,j,k]) == 1
        sol[i,j] = k
    end
end
# Display the solution
println(sol)
end

Here's the error:

After doing a little digging this appears to happen due the deprecation warnings generated by the code I copy-pasted from the JuMP website. If I remove these warnings, the compilation completes without throwing an error.

This is fixed when using Julia-0.5.
