Demo not running, s-function not found

Hi everyone,

it's one day that im trying to run the demos of the DSP builder but everytime that i try to run one of them i get the following errors:

S-function 'mip_control' does not exist

S-function 'mip_chanview' does not exist

S-function 'mip_cic' does not exist

And so on, it seems like that something is missing, I also tried to check the Model Dependencies and all the s-function called 'mip_...' are not found.

Does someone know how to solve this problem?

Thanks in advance

ps: i have installed quartus and dsp 10.1, matlab 2009b

    Are you running 64-bit MATLAB? Type mexext at the MATLAB prompt. If it says mexw64 or mexa64 then it's 64-bit. On windows, you need to install the 32-bit version. On Linux, run matlab with the "-glnx86" option.

    Yes, in fact I was running the 64-bit version, but now that i lunched the 32-bit one and tried to lunch the demo_fibonacci, i get the following errors:

    Invalid MEX-file quartus_path/mip_control.mexglx

    Invalid MEX-file quartus_path/mip_prim.mexglx

    what could it still be?

    thanks

    Sounds like your paths are not configured properly. Type: 

    getenv LD_LIBRARY_PATH

    There will be a long string (you'll have to scroll to see all of it), containing paths separated by colons. Look through the paths and see if it contains any that point into your Quartus or DSP Builder installation. Please list those here.

    Cool! I think now that problem is solved, but now I get the two following errors:

    Model error/ Unespected standard exception from MEX file/ What() is:boost::filesystem::create_directory: Permission denied: "../rtl"

    Could it be that I am not running the OS as root user?

    Thanks for your help

    Your problem is that you don't have permission to write to ../rtl.

    You have two choices:

    1) open up the Control block in the design you're generating and change the path to one that you do have permission to write to.

    2) change directory to one from which you can write to ../rtl

    Cool, it's working thanks!

    Another little problem, when i launch Quartus II and I start the compilation the Fitter gives to me an error:

    Current license file does not support the EP2C...

    I set a Cyclone II as device; how can I know which fpgas my license file supports?

    Probably best to ask this in a new thread (perhaps in a different forum) so that the right people look at it.
