This is the full .deb I modified.

Sorry for no upload before, I have no discovered that i can upload files til now :D .

I hope it be useful.

Cheers,
Demostenes

Edit: I don't know why is not possible to directly install .deb from the navigator (file type : unknown). Any ideas?. Try to save adding '.deb' to filename and install manually.

And thanks a bunch for the fix! :D

Gnuite :

This is the code I have added at your sources :

Quote:

static gfloat strtofloat(gchar *num)
/* Function to convert string to float number
***Note I have no check for errors in string***
*/
{
gfloat ret = 0.f;
gchar *pchar;
gfloat n;
gfloat dec = 0.f;

pchar = num;
while(*pchar != '\0' && *pchar !=' ') {
if (*pchar == '.')
dec = 10.f;
else {
if (dec) {
n = ((gfloat) (*pchar - '0')) / dec;
dec *= 10.f;
}
else {
n = (gfloat) (*pchar - '0');
ret *= 10.f;
}

ret += n;
}
pchar++;
}

return(ret);
}

and I have changed all references to 'atof' for 'strtofloat'.

Great code, great work, I have no problems to follow it.

Thanks. Demostenes.

Could it be that the atof function pays attention to the system locale, specifically, to the decimal separator? Demosthenes, if you open language/region in the control panel, what is the decimal separator set to?

I'm very interested in topo maps since the Google street maps do not cover Lithuania.

Google Satellite maps use a different URL scheme

Here's a function to convert the google street map coordinates (x, y, zoomlevel) to the quadtree index string used by the google satellite maps (http://kh0.google.com/kh?n=404&v=6&t=%s).

Code:

void convert(int x, int y, int zoomlevel, char * buffer)

{

    char * quadrant = "qrts";

    char * ptr = buffer;

    int n;

    *ptr++ = 't';

    for (n = 16-zoomlevel; n >= 0; n--) {

        int xbit = (x >> n) & 1;

        int ybit = (y >> n) & 1;

        *ptr++ = quadrant[xbit + 2 * ybit];

    }

    *ptr++ = '\0';

}

Here's a set of unit tests for this function.

Code:

#include <stdio.h>

#include <string.h>



int test(int x, int y, int zoomlevel, char * expected)

{

    char buffer[19];

    convert(x, y, zoomlevel, buffer);

    if (strcmp(buffer, expected) != 0) {

        printf("failure with (%d, %d, %d): expected \"%s\", got \"%s\".\n",

               x, y, zoomlevel, expected, buffer);

        return 1;

    }

    return 0;

}



int main()

{

    int failures = 0;

    failures += test(0, 0, 17, "t");

    failures += test(0, 0, 16, "tq");

    failures += test(1, 0, 16, "tr");

    failures += test(1, 1, 16, "ts");

    failures += test(0, 1, 16, "tt");

    failures += test(0, 0, 15, "tqq");

    failures += test(1, 0, 15, "tqr");

    failures += test(2, 0, 15, "trq");

    failures += test(3, 0, 15, "trr");

    failures += test(2335, 1295, 5, "trtqsqqqrssss");

    if (!failures) {

        printf("All tests passed.\n");

        return 0;

    } else {

        return 1;

    }

}

Did I mention that I would be very happy to see Google satellite map support in MaemoMapper? ;)

Ok, this morning I was able to try the app w/voice on my way to a store. Let me say it is EXCELLENT! There is only one thing that would make it better. There should be a setting in which the user can change how far away to make the voice command. In my experience, the commands were said a little too early (I was far away from the intersection when they were said.) If I were going to a place I didn't know, it may be a problem remembering the command by the time I approached the street. Thank you once again for a fantastic app!!

Really is 'c' funtion 'atof' in linux language dependant? I have been a windows/dos programmer for long time and never base functions in c have been language dependant. If that's true, I have to take care for future developments in linux :D .

Here's a patch that adds Google satellite map support to MaemoMapper:
http://mg.pov.lt/maemo-mapper-0.1-su...sat-maps.patch

Satellite map support in MaemoMapper

And here's the package with that patch applied.
