DSP Builder on Ubuntu Linux

Hi all,

I installed Matlab r2008a, it works fine.

I installed Quartus II 9.0, it works fine

I have had problems with DSP Builder.

The installation completed with no errors and in simulink are now present both "Altera DSP Builder Blockset" and "Altera DSP Builder Advanced Blockset".

When I open a new model and I drag any block in from Altera blockset (i.e. gain block) I get the following exception in the matlab command window:

Error in block : untitled/Gain

Java exception occurred:

java.lang.UnsatisfiedLinkError: com.altera.dspbuilder.simulation.Block.rename(Ljava/lang/String;)V

at com.altera.dspbuilder.simulation.Block.rename(Native Method)

at com.altera.dspbuilder.simulation.Block.setName(Unknown Source)

at com.altera.dspbuilder.simulation.Mask.init(Unknown Source)

this error issues for every operation I do.

I don't get how to I solve this issue, I checked the file permissions and environment variables.

Has anyone experience of DSP_builder on Ubuntu linux?

Thank you all in advance!

    SOLVED

    the environment variable QUARTUS_ROOTDIR, even if exported in the .bashrc file, is non set if the installation is executed by the command

    $sudo ./install --setup_matlab

    The variable is set if the superuser is invoked by the command "sudo -s" before.

    In this way the installation command# ./install --setup_matlab

    works properly.
