All of the "gr::buffer::allocate_buffer: warning: tried to allocate"
warnings are normal. Only the last line ">>> Done (return code -11)" is
significant. Usually, when you see the done message with a return code,
there was a segfault.
If you run dmesg, you can see the segfault. In this case, it was:
[1341187.638565] dvbt_bit_inner1[5931]: segfault at 0 ip
00007f89113238d3 sp 00007f88e67fb150 error 6 in
libgnuradio-dtv-3.7.11git.so.0.0.0[7f8911282000+13d000]
Which shows that there was a segfault in the Bit Inner Deinterleaver block.
The reason for this segfault is due to some recent commits. I'm
investigating right now. I should have a fix soon.

Hi,
Finally, I suceed to install with PyBOMBS:
"GNU Radio Companion v3.7.10-38-g45718683" + gr-gsm + lacrosse + lte.
Now I would like to work with gr-dtv.
I' m trying to work with "dvbt_rx_8k.grc" example.
I have downloaded "advc16.cfile" (934.6Mo).
File source has "advc16.cfile" path.
File sink "advdvbt.ts" has path in my home directory.
When I run "dvbt_rx_8k.grc" example, "advdvbt.ts" file is build with 0
byte size and I get the following messages:
gr::buffer::allocate_buffer: warning: tried to allocate
10 items of size 6048. Due to alignment requirements
128 were allocated. If this isn't OK, consider padding
your structure to a power-of-two bytes.
On this platform, our allocation granularity is 4096 bytes.

>>> Done (return code -11)
Do you have any idea why "advdvbt.ts" file is not build has expected?
Best regards.
