Comm USRP installation with R2012a / Linux

I am running Ubuntu 12.04 with Matlab R2012a and I am trying to install the USRP functionality of the comm toolbox. I have the version "usrp_v3_0_R2012a". The first problem that I am having is that the "setupsdru" script is trying to add the path

/home/danielj/Documents/usrp_v3_0_R2012a/commusrp/bin/glnx86

which does not exist. A very similar folder does exist:

/home/danielj/Documents/usrp_v3_0_R2012a/commusrp/bin/glnxa64

But when I run

computer('arch')

MATLAB returns

glnx86

So, I tried changing the name of the folder from 'glnxa64' to 'glnx86' and this does remove the warning I was having. Next, I run

findsdru

which produces the following error:

Undefined function 'usrp_uhd_mapi' for input arguments of type 'char'.

Error in mapiPrivate (line 19)
            [retStr, errStat, errStr] = usrp_uhd_mapi(cmd);

Error in findsdru (line 25)
    [flatAddrList, errStat, errStr] = mapiPrivate('findsdru');

I was not sure if this error and the earlier warning are related. So I posted both. Any help on resolving this would be appriciated!

Thanks

I would speculate there is only 64 bit support on Linux, but I have not found the requirements documentation.

Renaming the folder may have temporarily gotten past the error for you, but the primary issue here is that you have 64-bit MATLAB installed on a 32-bit machine. Looks like this was done in error? Could you run the command "mexext" and see if it returns glnxa64 - this indicates whethere 32- or 64-bit MATLAB is installed. I haven't seen this kind of issue before, but I'd recommend calling MathWorks Installation Support.

Thanks for the reply. Running "mexext" returns

mexglx

which I think is associated with "glnx86". I think the problem may be that I have 32-bit machine and Matlab, but a 64-bit version of the USRP toolbox.

[Kaustubha Govind]

Strange. Did you install the USRP toolbox separately after installing MATLAB? Perhaps Installation Support can help you get the 32-bit version.

[Daniel]

Yes, I installed MATLAB first and then the USRP support package. Thanks for your help! I haven't found any details on the supported architectures. I think I need to get some help from MATLAB at this point.

Okay, looks like you may have installed the 64-bit version of the package instead of 32-bit.
