Hi,
I tested out the new release 3.6.3 on an old IBM thinkpad laptop (and I
mean old–about ten years old) running Ubuntu 10.04. I did this before
testing it out on the laptop I have the old version running fine (a Dell
Latitude running Ubuntu 12.04).
Anyway, I used the build script on the old IBM, and everything compiled
until it got to here:
[ 38%] Building C object src/CMakeFiles/rtl_adsb.dir/rtl_adsb.c.o
Linking C executable rtl_adsb
librtlsdr.so.0.0.0: undefined reference to `libusb_error_name’
Does anyone have any idea what could be giving the error. I used the
“verbose” option, and here is the last few lines of the build:
------------------ cut here -----------------------------------------
