Compiling issue - rtlsdr_set_bias_tee

[sm3ulc]

On a updated debian/buster i get:

[ 67%] Linking C executable sdr_server /usr/bin/ld: libsdr_serverLib.a(core.c.o): in function start_rtlsdr': core.c:(.text+0x54c): undefined reference tortlsdr_set_bias_tee' collect2: error: ld returned 1 exit status make[2]: [CMakeFiles/sdr_server.dir/build.make:89: sdr_server] Error 1 make[1]: [CMakeFiles/Makefile2:258: CMakeFiles/sdr_server.dir/all] Error 2 make: *** [Makefile:141: all] Error 2

Old rtl-lib? minimum version to run?

apt-cache show librtlsdr-dev | grep Version Version: 0.6-1

It looks like apt has old librtlsdr. Without the latest bias-tee fixes. I will fix that.

In the meantime, can you build rtl-sdr by steve-m: https://github.com/steve-m/librtlsdr/commits/master

I also received the error on a RPI 3B

libsdr_serverLib.a(core.c.o): In function start_rtlsdr': core.c:(.text+0x8b0): undefined reference tortlsdr_set_bias_tee' collect2: error: ld returned 1 exit status CMakeFiles/sdr_server.dir/build.make:99: recipe for target 'sdr_server' failed make[2]: [sdr_server] Error 1 CMakeFiles/Makefile2:178: recipe for target 'CMakeFiles/sdr_server.dir/all' failed make[1]: [CMakeFiles/sdr_server.dir/all] Error 2 Makefile:138: recipe for target 'all' failed make: *** [all] Error 2

Version: 0.5.3-11

TY!

Using the https://github.com/rtlsdrblog/rtl-sdr-blog repo seem to work fine. Important since it contains support for direct sampling.

Fixed. The minimum librtlsdr version is 0.5.4.
