Hi Franco
I just looked thru those steps and they were followed,
Including the section
f you want to change installation paths to something more specific, the cmake line could look like this:

cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr -DLIB_INSTALL_DIR:PATH=lib64 -DLIB_SUFFIX=64 -DSOAPY_SDR_ROOT=/usr ..
as when I found the install path was /usr/local/ , iI uninstalled and did it again installing in /usr

It doesn't help when the API gets installed in /usr/local/lib
and soapy looks in /usr/loca/lib64
I've fixed that, as

Code: Select all

$ SoapySDRUtil --info

I am glad you found the problem with the bad USB cable.
How did you install 'gqrx'? From source or with a binary package?

Hi Franco

I built from source , pulled from git
strange both cables wok fine with my printer.
just rebuilding gr-sdrplay in case it has to have a connected rsp when running qmake, doesn't make sense , but grasping at straws

hi
It does look like gr-osmosdr must be built after soapySDR has found the RSP

Now I have gqrx working, but before until SoapySDRUtil had found the no modules appeared in GRC
not very impressed with the demod , but need to play a bit more ; demod from a 2.7KW transmitter 5 kms LOS from
here on Band 2 WBFM was not very good.

I am really glad you got 'gqrx' to work.

Hi Franco

So I'm I.
The install on linux really needs to be sorted out.
There are standards on all the versions of linux, and BSD, where libs put in directories dependent on their architecture, 32 or 64 bit.
It would help if theses were followed, and would have prevented a lot of the problems i encountered.
But at least now it looks like it working
