Linking a DLL using Nios2 IDE

Hi,

I'm trying to link the FFTW library to an example based on the Hello_world template but in vain. Here's the error:

***[hello_world_2.elf] Error 1

obj/hello_world.o *In function 'main': undefined reference to 'fftw_malloc'

How do I link a DLL to a piece of code in Nios IDE?

Thanks for any help.

    HI,

    Regarding the same problem, if I specify the path of the library in "Project properties" and use linker flags -lfftw3, i get the following error:

    ***[hello_world_2.elf] Error 1

    (path) ... /nios2-elf/bin/ld cannot find -lfftw3

    Any help is most welcome. Thanks!
