Hi all,
     I am working on driver,
     How to used float variables in diver code? How to do arithmetical
calculation in driver code?
     Platform: x86
     Kernel: 2.6.29

     If I added float variables in my driver code :
     eg:

    float a,b,c,d;
    float ans;
    ans = (float)(1.0 / (a * b + c * d);



    following error occured:

ERROR: "__fixdfsi" [drivers/my_driver/mydriver.ko] undefined!
ERROR: "__divdf3" [drivers/my_driver/mydriver.ko] undefined!
ERROR: "__floatsidf" [drivers/my_driver/mydriver.ko] undefined!






Waiting for reply...

Thanks,
Sachin Bhangale
