HELP FOR C2H !! Is there Any Hope to use It or no ?

Hello, I am trying to use C2H under NIOS IDE TOOL (not SBT tool). Its the only one tool that it work (I hope). Till know, I never seen C2H working !!!!! I created project under the legacy NIOS II IDE TOOL abec I added my function for Acceleration. When I click right on the C2H console , I gives me error : eclipse.buildId=M20060629-1905 java.version=1.6.0_14 java.vendor=Sun Microsystems Inc. BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=fr_FR Command-line arguments: -os win32 -ws win32 -arch x86 Error Sat Dec 25 14:07:17 CET 2010 Context menu missing standard group 'org.eclipse.ui.IWorkbenchActionConstants.MB_ADDITIONS'. (menu ids = [com.altera.ide.chac.views.ChacView]) part id = com.altera.ide.chac.views.ChacView) The SBT and the NIOS IDE Tools uses ECLIPSE ! Is some Guru know how we can use this Tool C2H or tell us that it don"t work and we can do other think ! Thanks

    Hello,

    I used C2H to optimize SQR function :

    This function compute SQRT of 16 bits unsigned integer number. results is on 8 bits.

    unsigned short sqr(unsigned short Xio){

    register unsigned short V= 1<<14;

    register unsigned short Z=0;

    register short i;

    register int temp;

    register unsigned short X=Xio;

    for(i=7;i>=0;i--){

    Z=Z+V;

    temp=((X-Z)>=0);

    X=X-(temp ? Z : 0);

    Z=Z+(temp ? V : -V);

    Z=Z/2;

    V=V/4;

    }//Fin pour

    return Z;

    }

    After adding sqr function to C2H and configurer in release mode, here is result of make :

    make -s all includes

    I am Professor in university of PAris,

    If I cannot have any information, I think I will cancel my course on C2H and Altera Tools.

    Thanks for your Help !
