  Hi Everyone,

  I am quite new to using buildroot and embedded linux systems in general. However, I have managed to use buildroot to get a (nearly) working system up and running for an at91sam9263 board. (kernel v 2.6.22, uClibc v 0.9.29)

   

  I have one annoying problem though. One of the packages I am compiling from source uses C's "double" type, and this does not seem to be behaving as I need it to.

   

  I have created a simple example program:

   

  .

  int main (int argc, char *argv[])

  {

  double test;

  test = 1;

  fprintf(stderr, "Test double = %f.\n", test);

  }

   



Should you not be using "%lf" instead of "%f" ?

   fprintf(stderr, "Test double = %lf.\n", test);

   fprintf(stderr, "Test double = %f.\n", test);

Best Regards
Ulf Samuelsson
