Module search trys to open files that are not shared libraries

[ion-concepts]

Noticed that Soapy is pretty indiscriminate (under OSX 10.10) and verbose about trying to open anything under {INSTALL_ROOT}/lib:

macbook-cmh:build ianb$ SoapySDRUtil --probe="driver=uhd"

This is more like the windows sdk project. This is the SoapySDR project: https://github.com/pothosware/SoapySDR/issues

So thats odd. What does SoapySDRUtil --info say? This will tell us where its looking

Its supposed to search

• install_root/lib/SoapySDR/modules
• and $SOAPY_SDR_PLUGIN_PATH

and install_root will be the CMAKE_INSTALL_PREFIX unless this env var is set $SOAPY_SDR_ROOT

[ion-concepts]

Sorry if you want to move the issue go ahead...I'm schooled for future issues now.

I don't have any $SOAPY prefix enviromentals defined. And my install root in CMAKE was : /Users/ianb. I do have some generic enviromentals such as $LIBRARAY_PATH defined.

Available factories...null, uhd,

FYI. I removed $LIBRARY_PATH and $DYLD_LIBRARY_PATH but no difference

[guruofquality]

I think SoapySDR is working. It actually shows uhd loaded and doesn't have any recognizable error prints from SoapySDR.

I have a feeling that once SoapySDR loads uhd support that its UHD static initialization trying to load everything in lib/. Those prints are from UHD is what I am saying.

You dont have UHD_MODULE_PATH set do you?

Just for reference:

• UHD searches here: https://github.com/EttusResearch/uhd/blob/master/host/lib/utils/paths.cpp#L193
• Loads here: https://github.com/EttusResearch/uhd/blob/master/host/lib/utils/load_modules.cpp#L65
• And if you suspect Soapy, it loads here: https://github.com/pothosware/SoapySDR/blob/master/lib/Modules.in.cpp#L184

Unless its a weird install path or env variable set, you might need to add a few prints to see where its looking~

Anyway, I think we figured this out. Just open an issue on the SoapySDR or relevant tracker if it persists. Thanks!
