Talk:InstallingGRFromSource on Raspberry Pi

From GNU Radio
Jump to navigation Jump to search

Hi, I'm a beginner and I'm having some problems installing UHD.

When I follow the official tutorial and execute "cmake -DNEON_SIMD_ENABLE=OFF -DCMAKE_INSTALL_PREFIX=/usr/local ../", the following warning appears:

CMake Warning (dev) at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:438 (message):

 The package name passed to `find_package_handle_standard_args` (PkgConfig)
 does not match the name of the calling package (LIBUSB).  This can lead to
 problems in calling code that expects `find_package` result variables
 (e.g., `_FOUND`) to follow a certain pattern.

Call Stack (most recent call first):

 /usr/share/cmake-3.22/Modules/FindPkgConfig.cmake:99 (find_package_handle_standard_args)
 cmake/Modules/FindLIBUSB.cmake:6 (include)
 lib/CMakeLists.txt:62 (find_package)

This warning is for project developers. Use -Wno-dev to suppress it.

I've searched pretty much everything I can find on the net and still haven't been able to solve the problem, so looking for help here.

· operating system: Ubuntu 20.04

thank you very much!


It's been a while since I've done a build from source. What version of GNU Radio are you building? Is there a reason that a PPA would not work for you?

If a PPA doesn't serve your needs, it would be best to take this issue to the Matrix General Chat or to the discuss-gnuradio newsletter.
