Worked (or at least as far as I can tell...) on Mojave 10.14.5 today. (2019-06-12)

I have made a version of these instructions based on MacPorts:

Hi! Under macOS Catalina (10.15.7) I am following these instructions. Among the previous commands,

I issued the brew install libusb and it finished with no errors. But, later when inside rtl-sdr/build when running make, I get:

user@MBP % make

Any ideas or help are appreciated.

Try this make LIBRARY_PATH=/usr/local/lib

I had this error last week. I found this https://stackoverflow.com/questions/65296289/fatal-error-libusb-libusb-h-no-such-file-or-directory-librtlsdr-install-for-gn Tsyvarev <https://stackoverflow.com/users/3440745/tsyvarev> recommends installing pkg-config then retrying. According to the project's CMakeLists.txt <http://osmocom.org/projects/rtl-sdr/repository/revisions/master/entry/CMakeLists.txt#L72>, it expects either libusb to be found with pkg-config or, if pkg-config is not available, libusb parameters should be filled manually: LIBUSB_INCLUDE_DIRS should be set to include directory (/usr/include/libusb-1.0 in your case) and LIBUSB_LIBRARIES should be set to the libusb library (for link with). Though it seems to be simpler to install pkg-config. – Tsyvarev <https://stackoverflow.com/users/3440745/tsyvarev> Dec 14 '20 at 22:48
