    (.text+0x25f6): undefined reference to `__muldf3'

    You need to link with libstc++ or whatever it's called. Are you sure you don't want to use the "g++ -o target objectfile1.o objectfile2.o ..." instead, as the g++ driver will know how to call ld correctly for a C++ project.

    you are right Matsp..Using g++ instead of ld eliminate the common undefined errors.
    And i got the following error which iam crying to resolve.
    undefined reference to `_register_handler'
    Is there any specific library do i need to link for this function?

    thanks

    I have no idea what the function "register_handler()" is - but I suspect it's something in your code, or a library that your code should use. Googling for "register_handler" finds LOTS of different uses of that name, so not much help. Perhaps you can do "man register_handler" on your system?
