Issue at amke step while building SoapyUHD

Hi,

I have an issue at make step:

$ make

Also I installed SoapyUtil and the device is detected:

$ SoapySDRUtil --probe="driver=novena"

An idea about how to fix this ?

Not sure. Perhaps there is both a source install and package install of libuhd? What is the output of cmake (it prints the uhd development paths). And can you share the install paths of libuhd.so? like updatedb && locate libuhd.so

Hi,

Thank you !! I solved it, I just noticed I have two uhd libs installed :(
