I'm trying to build 0.47.04-r2 with soundsense support and here is what I am getting for output

Would be grateful for any help resolving these.

Should note I am on Kubuntu 20.04

[ALL  ]      /usr/bin/ld: cannot find -lSDL
[ERROR]      collect2: error: ld returned 1 exit status

This error means that the compiler can not find the library 'libSDL.so'. It should be provided by package: libsdl-dev or libsdl1.2-dev

[kylemiller3]

Thanks installing libsdl1.2-dev fixed the issue. This may be needed to be mentioned in the setup instructions.
