Midiout build error

Support, Help & Resources

Hi! Before I say this I should probably mention that I’m on Solus OS, so I have cloned the sonic-pi repo and I’m starting to build it.

During ./linux-prebuild.sh I get the following error:

/home/benstigsen/Downloads/sonic-pi/app/external/sp_midi/src/midiout.cpp: In member function ‘void MidiOut::send(const std::vector<unsigned char>*)’:
/home/benstigsen/Downloads/sonic-pi/app/external/sp_midi/src/midiout.cpp:62:28: error: invalid conversion from ‘const std::vector<unsigned char>*’ to ‘std::vector<unsigned char>*’ [-fpermissive]

What do I do?

@benstigsen - it may be more useful to raise this as a ticket on GitHub - we try to manage all build-related issues there :slight_smile: happy to try to troubleshoot this over there if you’re able to do that :+1:
