[GRASS-user] grass70 start problems

Hello,

I've installed the latest cvs version on an ubuntu hardy heron.
When I start grass at a certain mapset, it breaks because it finds ANY .gislock that is set at any mapset in that location. Then it mentions that concurrent use of mapsets is not allowed.

Any hint?

Thanks
Manuel

Manuel, all,

GRASS 7 development has finally really started:
http://lists.osgeo.org/pipermail/grass-dev/2008-August/039264.html

GRASS 7 will be unusable for a while, better to switch to 6.4 if
you want to remain productive.

Forgot to add the web page where you find instructions to get 6.4.svn:

While that's reasonable advice overall, I suspect that this particular
problem may not be related to the recent changes.

Hello,

I had 6.3 running and now also 6.4. Works fine!

Thanks!

Hy list,
could anybody help me to declare a 3D matrix in C GRASS module. I've to load several raster map with same location but I've an error in run time if I declare with G_malloc/G_calloc like that:
double ***mat;

mat=(double***)G_malloc(ndimension*(sizeof(double));

thanks

To implement variable-size multi-dimensional arrays in C, you have two
options:

1. Allocate a single contiguous block and calculate the indices
yourself, e.g.:

  double *data = G_malloc(width * height * depth * sizeof(double));

  #define DATA(x,y,z) (data[((z) * height + (y)) * width + (x)])

  ...

  /* read element */
  v = DATA(x,y,z);

  /* write element */
  DATA(x,y,z) = v;

2. Create arrays of pointers:

  int i, j;
  double ***data = G_malloc(depth * sizeof(double **));
  for (j = 0; j < depth; j++)
  {
    data[j] = G_malloc(height * sizeof(double *));
    for (i = 0; i < height; i++)
      data[j][i] = G_malloc(width * sizeof(double));
  }

  ...

  /* read element */
  v = data[z][y];

  /* write element */
  data[z][y] = v;
