I need to modify the SONAME of some gnuradio libs.
In the gnuradio/volk/CMakeList.txt there is an entry
set_target_properties(volk PROPERTIES SOVERSION ${LIBVER})
that sets the SONAME. But how is this done for other libs like
gnuradio-runtime or gnuradio-pmt.
I did not identfy the statements

Hi Patrick,
the typical problem with C++ blocks is that people add public methods to
their _impl, but forget to declare these same methods in their public
non-impl class.
Have you done the same expand magic with the header in your

Best regards,

Hi Volker - Actually, the command you quote just sets the -version- of
the library, not the name. The name is set by default as the target
name, though one can change the name to something else via a similar
set_target_properties command. Hope this helps! - MLD

As I said, if that's the case, avoid using function probes but just use
the MPSK estimator (not the estimator probe), and write your own block
that just takes the tags that come from that, and translates them to
messages that you send to another block that does something useful with
them (e.g.
Every memoryless modulation scheme can be described as M vectors in an
N-dimensional space.
So the chunck-to-symbols requires as dimensionality parameter the N and
then it needs this array of numbers
s11, s12, ... s1N,
s21, s22, s2N,
...
SM1, sM2, ... sMN
So a 2-dim orthogonal scheme is
One way to do this is to create a flowgraph, such as foo.grc. This will
generate a Python file that you can import into another file, bar.py:
#!/usr/bin/env python2
import foo

tb = foo.foo()
# custom code
print samp_rate:, tb.get_samp_rate()

A quick look at the source reveals NumPy is used extensively in GNU

most of GNU Radio can install properly even if NumPy is not installed or

To be more specific:
Is pmt_to_python.py required as that's the place wher numpy is called.
But if this is required gnuradio should not compile without numpy.

Yes, pmt_to_python.py does use numpy. But, it looks like none of the
actual build for gnuradio-runtime (including pmt) requires numpy to be
installed. So, it's just used post-install. Hence, maybe why it's not
listed as a direct dependency? - MLD
On Mon, Jul 6, 2015, at 04:16 PM, Volker Schroer
To clear this up: pmt_to_python is a only a convenience file, but all
Python blocks require numpy. So, if you're building GNU Radio with
Python enabled, CMake should fail without Numpy installed. As you point
out, this is a bug in our CMake.

Dear Mark,
dozens of options -- you could just use the ZMQ sinks/sources to send
these samples to GNU Radio on the target PC, but you could also just
take these float samples, and shuffle them into the UDP sink, and

Numpy should probably be a hard requirement -- Python blocks won't work
properly without it, even disregarding this specific module.
How can I come around this problem without installing numpy ?

That means,there is a bug in cmake. If numpy is required , then gnuradio
should not build if numpy is not found.
But if I remember well, in earlier days of gnuradio pmt was not required.

Thanks much, Marcus. That was the issue. I had missed adding the declarations
