Hi! I wanted to build firefox-tor-browser-68.2.0esr-9.0-1-build2 (torbrowser 9.0.1) on NetBSD from the source tarball, but I stumbled over a couple problems. The first one, .mozconfig contains --disable-eme but configure doesn't like it: mozbuild.configure.options.InvalidOptionError: --disable-eme is not available in this configuration Is this a NetBSD-specific issue or more general? The second one: --- begin --- The error occurred while processing the following file: /scratch/security/tor-browser/work/firefox-tor-browser-68.2.0esr-9.0-1-build2/browser/extensions/moz.build The underlying problem is we referenced a path that does not exist. That path is: /scratch/security/tor-browser/work/firefox-tor-browser-68.2.0esr-9.0-1-build2/browser/extensions/tor-launcher/moz.build Either create the file if it needs to exist or do not reference it. --- end --- The directory browser/extensions/tor-launcher does not exist in the tarball, which looks like a problem with the tarball to me. Suggestions? Thanks, Thomas
