Compilation of Ron Economos' gr-dvbtx for GNU Radio 3.8 - help needed

[Ralf Gorholt]

Dear all,

I have tried to compile Ron Economs’ block gr-dvbtx from
github.com/drmpeg/gr-dvbtx for GNU Radio 3.7.11 and 3.8.2 but I have
noticed several problems.

1) In both environments compilation stops because of an error:
"gr-dvbtx/lib/dvbtx_ofdm_sym_acquisition_impl.cc:54:68: error: cannot
convert ‘uint32_t* {aka unsigned int*}’ to ‘uint16_t* {aka short
unsigned int*}’ in argument passing volk_32f_index_max_16u(&peak_index,
&datain[0], datain_length);"

In order to be able to compile the module, I have declared peak_index as
uint16_t but I don’t know if this is the correct way to get rid of this
error. For GNU Radio 3.7 everything seems ok now. The module is compiled
and appears in the list of modules of GNU Radio Companion. Is this
correction ok?

2) CMakeLists.txt expects GNU Radio version 3.7.2:
"find_package(Gnuradio "3.7.2" REQUIRED)". In order to compile for
version 3.8.2, I had to adapt this line.

3) Now I can compile the module for GNU Radio 3.8, but after "make
install" and "ldconfig", GNU Radio Companion does not show the module in
the list. Install prefix is /usr. I have noticed that the compiled
module for version 3.7 has a version information in the name:
"libgnuradio-dvbtx-1.0.0git.so.0.0.0" but the one for version 3.8 has
not: "libgnuradio-dvbtx-...so.0.0.0". Could this be the reason for the
problem? The version is set in CMakeLists.txt. Why is it empty when
compiled for version 3.8?

Could somebody please give me a hint what I have to do to get this
module compiled and installed for GNU Radio 3.8? I would like to use it
on a more recent version of GNU Radio than 3.7.

Thank you very much for your help!

Kind regards,

Ralf
