Soapy Sales Show

Postby rec » Fri Mar 18, 2016 3:19 am

So I went through one of the approved paths for installing software on Ubuntu and I've decided that the SDRplay API installed code compiled against an out of date version of SoapySDR, so it throws an error dynmically loading a library, because of an resolved symbol. Or something like that.

The solution, which was buried somewhere in the instructions for CubicSDR, is to install the SDRplay API "package", compile and install SoapySDR from github, compile and install SoapyRTLSDR from github, and compile and install SoapySDRPlay from github. That last step overwrites the faulty library that sdrplay.com is giving us to install.

So, let's see if I can recreate this.

1) Install SDRplay API from sdrplay.com

Code: Select all

rec@pixil:~/Downloads$ sh SDRplay_RSP_MiricsAPI-1.9.4.run
Verifying archive integrity... All good.
Uncompressing SDRplay Mirics API Install Package V1.9.4  100%

Remove old header files...
Install /usr/local/include/mirsdrapi-rsp.h

Libusb found, continuing...
Installing SoapySDRPlay...

Finished.


2) Try SoapySDRUtil looking for SoapySDR::loadModule error

Code: Select all

rec@pixil:~/Downloads$ SoapySDRUtil --probe

4) Probe again, still the error, but notice that the name of the missing symbol has changed.

I only noticed the change in the mangled symbol name while putting together this script. Maybe the sdrplay.com version of SoapySDRPlay is compiled with different options than SoapySDR?

You need to build SoapySDR and SoapySDRPlay before SoapySDR will work - if you have a 32bit OS that might be why SoapySDR didn't work after the API install - we only distribute the 64bit version.

Best regards,
