 Then you should be all set to build the software with `cmake` and `make` as discussed earlier.
 
-  - Note1: if you are on Leap you will need a more recent g++ compiler so in place of `gcc-c++` use `gcc5-c++` or `gcc6-c++` then add the following in the cmake command: `-DCMAKE_C_COMPILER=/usr/bin/gcc-6 -DCMAKE_CXX_COMPILER=/usr/bin/g++-6` (for gcc 6) and then `-DCMAKE_INSTALL_PREFIX:PATH=...` for the custom install path (not `-DCMAKE_INSTALL_PREFIX=...`)

-  - Note3 for udev rules: installed udev rules for BladeRF and HackRF are targeted at Debian or Ubuntu systems that have a plugdev group for USB hotplug devices. This is not the case in openSUSE. To make the udev rules file compatible just remove the `GROUP` parameter on all lines and change `MODE` parameter to `666`.

   - Note4: A package has been created in openSUSE thanks to Martin, see: [sdrangel](https://build.opensuse.org/package/show/hardware:sdr/sdrangel). It is based on the latest release on master branch.
