Has this issue been resolved? If I export the UHD_MODULE_PATH = the .so file it will find the gain block, but it prints a bunch of error strings trying to open every file in the directory. If I do not set the UHD_MODULE_PATH, I cannot find the block. How can I get around this? I’m trying to write C code to test the RFNOC block and am not interested in only gnuradio usage. Also setting -Wl,--no-as-needed in the target_link_libraries of CMakeLists.txt did not resolve the issue either.

Is there a reason why this does not get reflected in the usrp probe? I am running it on a E320. I built my bit image using the OOT approach. Moved it over and the .so created for my block. Do I need to bring over the block yml file or something? Try setting the UHD_MODULE_PATH environment variable to the location of your .so file for your block and re-run the probe. Brian

Don't put non-.so files in the directory. Problem solved?
