[Discuss-gnuradio] GR-UHD detected ABI compatibility mismatch with UHD Solved

[Andres Felipe Betancur Perez]

Hi.

I had this issue on GNU Radio:

-----------------

Using Volk machine: avx_64_mmx

Traceback (most recent call last):

  File "/home/tojo/top_block.py", line 118, in <module>

    tb = top_block()

  File "/home/tojo/top_block.py", line 81, in __init__

    channels=range(1),

  File "/usr/local/lib/python2.7/dist-packages/gnuradio/uhd/__init__.py", line 122, in constructor_interceptor

    return old_constructor(*args)

  File "/usr/local/lib/python2.7/dist-packages/gnuradio/uhd/uhd_swig.py", line 1727, in make

    return _uhd_swig.usrp_source_make(*args)

RuntimeError: 

GR-UHD detected ABI compatibility mismatch with UHD library.

GR-UHD was build against ABI: 3.4.0-3,

but UHD library reports ABI: 3.4.0-0

Suggestion: install an ABI compatible version of UHD,

or rebuild GR-UHD component against this ABI version.

-----------------

I used these slides to solve the problem:

Review the 22th slide

I installed the UHD from source code to force the needed version. The USRP I've been using is the NI-2900 of National Instruments (actually is the same as B200 from Ettus research).

I hope this can be helpful for all people with this driver problem.

Best regards.
