Now that I've had time to look into it, it builds fine with "#include <unistd.h>" added to fileutils.cpp. That does raise the question of why it worked for everyone else, but that's an easy enough fix.
Hi Philip, sorry nobody looked into this until now. On Linux, mkdtemp lives in stdlib.h, which is already included. Is this still an issue for you on macOS? If it is, this should probably be ported to something like QTemporaryDir, or we should add the include (if the reason for de3a0b069c08 still applies).
No answer, closing for now. Feel free to reopen if it is still an issue.
