 Can anyone explain why this fails? This piece of code runs perfectly
 using weave.inline and type_converters = blitz..
 
 Obviously it can't handle 2D arrays anymore. It's just a stupid
 example to illustrate that. 
 
 Thanks,

 CODE :
 
 
 mod = ext_tools.ext_module('ravg_ext')
 
 test = zeros((5,5))
 xlen = 5
 ylen = 5
 
 code = 
  int x, y;
 
  for( x = 0; x  xlen; x++)
  {
 for( y = 0; y  ylen; y++)
 {
 test(x,y) = 2;
 }
  }
 
 
  
 ravg = ext_tools.ext_function('ravg', code, ['xlen', 'ylen',
 'test'])
 mod.add_function(ravg)
 mod.compile(compiler = 'gcc')

Re: [Numpy-discussion] Weave Ext_tools converters not working??

2008-11-17 Thread Søren Nielsen 
because it's written as C code using the blitz type converter..

I found the answer to my own problem. I added type_converters =
converters.blitz in the ext_functions function call.
