hi,

      In my application iam using trignometric functions, when i want to display the value of any trignometric functions
      after building target it gives "undefined reference to sin" . If i want to use the value of any trignometric function in 
      another trignometric function it is giving the same error.

      i added the statement in open AT project wizard in wm newscript additional options 
     " -extlib C:\OpenAT\IDE\GCC\4.0.1.1\arm-elf\lib\thumb\interwork -libname libm.a      "

Hi, to add a external library to your OAT App, the firts step is that you made and the second is:

Find the make file of yor project and add handly in EXTERNAL_LIB_LIST like this

#------------------------------------------------------------------------------

List of libraries real names to use for making binary file

#------------------------------------------------------------------------------
EXTERNAL_LIB_LIST =
/cygdrive/C/OpenAT/IDE/GCC/4.0.1.2/arm-elf/lib/thumb/interwork/libm.a \
