Nope, straight checkout from CVS. I had the same thought as you, so I checked it out twice with the same results. I also looked for SuperLU itself, but the only version I found out there was 2.0 which (surprise) doesnt compile with sparse (I think it's bundled with 1.2?)... Another question that's been bugging me now that I've been staring at sparse's source code... it looks to me like it's just a sparse matrix equation solver. I will need to instantiate very large "cubes", say 1e3x1e3x1e4, with low population densities (max around 20%, typically 5-10%). This 1e10 cube doesn't even allocate in Numpy/Scipy (smaller cubes actually crash my Win2K laptop), so I was _hoping_ that scipy.sparse would implement a "default value" array: i.e. the operation: x = zeros([1e3,1e3,1e3]) would be instantaneous as x would be an empty "shell" with 0 as it's default value. However, I don't see a capability like that in scipy.sparse's source code though. Am I missing it? is there anything like this for SciPy/NumPy? Thanks for all your help, Costas

Both setups work OK (well, cluster also fails on Cygwin, but I took it out), and they crash more-or-less with the same error ("parse error before numeric constant", below). Extensive Googling shows that this means a numeric constant is already used somewhere else, but I got no solution to work around it...

Ideas?

Thanks,

Are you sure you have the correct CVS files? This is odd for there to be a parse error in SuperLU. Did you modify this file somehow or not get a complete checkout.

You could erase this file and check it out again. You might try that for that whole SuperLU directory.

Good luck,
