Example of configuration for SDR source block in PothosSDR

[rast]

I am getting similar failures when running Gqrx on Mac mini:

I have PothosSDR binary installed on my PC
Together with it I have lot of static libraries in teh standard installation path (c:\Program Files\PothosSDR\lib)
I think the above installer sets some environment variables.
Building LoRa-SDR example fails to find my libs in c:\Program Files\PothosSDR\lib(If I copy all libraries from the above path to the LoRa-SDR building directory the cmake building completes OK)

Do I miss some environment variables and cmake can not find the libraries? Or how is it suppose to work?I had similar issues compiling Pothos in Windows which at the end appeared to be environment variables related.

A few more cmake tips if this helps. Cmake is just looking for where to find certain FooConfig.cmake package scripts. If you use the same CMAKE_INSTALL_PREFIX, it will usually find things. An alternative is to tell it where the Foo_DIR is located. Example

• -DCMAKE_INSTALL_PREFIX=c:/program files/PothosSDR
• Or -DPoco_DIR=c:/program files/PothosSDR/lib/cmake/Poco
• And pothos dev files have one too:
  • -DPothos_DIR=c:/program files/PothosSDR/cmake
