Macbook Pro M2 with MacOS Sonoma (14.5): error when intallig driver

[tau31]

Hi 👋 ,

I am trying to install the driver using the recommended instructions in the README for MacOS.

However, I get past the make stage with the following error:

~/gits/rtl-sdr-blog/build (master ✗) make LIBRARY_PATH=/usr/local/lib

I have little experience with compilation to even know what should I do here.

Could anyone give me a help here?

Thanks 👍

try brew install libusb after successfully compile and install, you will got error when running binary:

dyld[48941]: Library not loaded: @rpath/librtlsdr.0.dylib
  Referenced from: <E2264B6E-CC23-3008-BA26-3B5E7BC238BA> /usr/local/bin/rtl_test
  Reason: no LC_RPATH's found
[1]    48941 abort      rtl_test -t

then sudo install_name_tool -add_rpath /usr/local/lib /usr/local/bin/rtl_test then repeat this command for every rtl_* files in /usr/local/bin (rtl_sdr, rtl_fm and other) done.

As an alternative, instead of make LIBRARY_PATH=/usr/local/lib, try make LIBRARY_PATH=$(brew --prefix)/lib.
