Hi Ivan,

is it possible you've installed gr-lte into a place that python doesn't look in? You say you installed GNU Radio via an install script; are you referring to PyBOMBS, perhaps? In that case, make sure your "cmake" call when build gr-lte has a "-DCMAKE_INSTALL_PREFIX=/path/to/your/pybombs/prefix".

Best regards,

Dear all,
I have fresh install of GNURadio via install script.
I installed gr-lte via build from source as explained in readme.
I did p.5 in readme - compile hierarchical GRC blocks.
The flowgraph lte_top_block_siso has no missing blocks.
I am using my file as source.
When I run th flowgraph I am having following error:

Pls advise.

Best regards.
