Hi There…
Since upgrading to 3.2rc0 my app crash on android when it is launching…
This is the log…

i am using ndk r10c

Cannot locate atof() on android?

The issue is known and documented here.

https://code.google.com/p/android/issues/detail?id=73725

Cocos should probably use strtod instead of atof, but in the mean time, you can implement atof yourself in one of your source files to provide the symbol.

static __inline__ double atof(const char *nptr)
{
    return (strtod(nptr, NULL));
}
Which one to use, NDKr9d or NDKr10c? [SOLVED]

Thank you for the info…
can you tell me where i should put the code…
i didn’t specify that it was js branch i am using…

#4

Any cpp file should do. AppDelegate.cpp for example. Remove the static and inline for putting in a .cpp file.

#5

Ok thanks, i did that. Now i see rand is missing.
So i am looking around the net for the rand function.
What i really want to know, is what other functions are missing?

#6

The link I posted at the top documents a list of the functions that have changed I believe.

#7

so i add this…

int AppDelegate::rand(void)
{
    /* LINTED integer overflow */
    return (int)((next = next * 1103515245 + 12345) % ((u_long)RAND_MAX + 1));
}

but it still saying i am missing rand…

#8

The method signature needs to match. Don’t declare it as a c++ method.

use…

int rand()
{
}

Also for a better RNG you might try arc4random and see if that is available.
