I get the following error whenever I run rtl_biast, regardless of the parameters, or even with no parameters at all. rtl_biast: symbol lookup error: rtl_biast: undefined symbol: rtlsdr_close_bt My Ubuntu 18.04 computer has the following in /usr/local/lib librtlsdr.a That's the only place where any librtlsdr libraries are found. The problem started as soon as I compiled and installed rtl_biast. The error occurs even when I run rtl_biast when I'm in /usr/local/lib. I've tried: LD_LIBRARY_PATH=/usr/local/lib I've also tried sudo ldconfig I tried export PATH=$PATH:/usr/local/lib$ and verified that /usr/local/lib was in the path with echo $PATH I still get the same "undefined symbol: rtlsdr_close_bt" error message. I tried sudo apt-get autoremove gqrx-sdr to remove gqrx and all libraries, then reinstalled them with sudo apt-get install gqrx-sdr Same error message. I'm beginning to think I may never get my bias T powered preamp to work. |
It's not a good idea to run sudo make install with the bias tee software. Run it within the compiled src directory only. I think what has happened with yours is that you have multiple driver conflicts. I would suggest running apt-get remove rtl-sdr, deleting any librtlsdr remnants, then installing the RTL-SDR Osmocom drivers. Then compile the rtl_biast software, but do not make install it. |
I've compiled rtl_biast under raspbian stable.
Apparently rtl_biast is installing its librtlsdr.so in /usr/local, where the system doesn't look by default. This could be in the readme.
