Re: Fatal error messages

[Valentin Petzel]

Hello Alasdair,
midi appears to create a temporary file. The error seems to happen in line 51 
in midi-stream.cc. This temporary file should be placed in the current working 
directory if I’m correct.

Can you make sure you do have write access to the drive? If so, could it be 
that you have some sort of sandbox or AV thats hindering Lilypond to write 
files?
