Hi All, Problem solved:-)
There is a package soft66 which depends on libusb-1.0. On systems where I had installed this package my load at run-time fails because soft66.so loads libusb and libusb-1.0. I do not have this hardware and on systems where I did not install this package everything is fine. Now I have removed this package from the linker list and load it at run-time if needed (hopefully.) Now loading librtlsdr at runtime works without problems:-) Sometimes there is a trivial solution to difficult problems;-) 73 Leif
