libsdrPlaySupport.so cannot find libsdrplay_api.so.3.07 #44

Closed AsciiWolf closed 2 years ago

AsciiWolf commented 3 years ago

Fedora 34, SoapySDR-0.7.2-11.fc34.x86_64, SDRplay API 3.07.1, latest SoapySDRPlay3 master.

The installed libsdrPlaySupport.so cannot find libsdrplay_api.so.3.07 although it linked fine during the build process:

$ ldd /usr/local/lib64/SoapySDR/modules0.7/libsdrPlaySupport.so

However, the built libsdrPlaySupport.so in build dir (before installing it with sudo make install) does not have this issue:

Everything works fine after manually copying this file to the target directory: sudo cp SoapySDRPlay3/build/libsdrPlaySupport.so /usr/local/lib64/SoapySDR/modules0.7/libsdrPlaySupport.so

@AsciiWolf - I would run the following command first thing to make sure that the ld cache is refreshed:

sudo ldconfig

If you still keep having the same problem after the command above, please run the following command to make sure that /usr/local/lib/libsdrplay_api.so.3.07 is in the ld cache:

ldconfig -p | grep sdrplay

Another thing I noticed is that you seem to be running an older version of SoapySDR (version 0.7); perhaps you may also want to git clone and rebuild SoapySDR using the latest version (0.8) - I am on Fedora 34 too, and SoapySDR version 0.8 works without any problems here.

Hope this helps, Franco

Turns out it was a problem with Fedora not having /usr/local/lib in its ld library path by default. Was fixed by creating /etc/ld.so.conf.d/local.conf with this content:

/usr/local/lib
/usr/local/lib64

This worked for me as well
