I am getting some weird error about a invalid time base clock name after starting to create my own block. I did not see this just doing the simple pass thru RFnoc example. What would this mean?

Hi Jeff, I am getting this same error. Did you ever figure out the problem?

Following up on my previous email, I found that this error was happening when I set UHD_MODULE_PATH to allow UHD to find my RFNOC library had also linked my library explicitly in my custom app. Thus, if I ran uhd_usrp_probe, everything was fine because it found my library in the defined UHD_MODULE_PATH. But, when I ran my custom app, it loaded my explicitly linked library and then UHD also loaded the library in the path. This seemed to cause the mentioned error because if I simply "unset" the variable, everything worked fine.
