I am here because I am able to successfully upload the i386 build of my program to launchpad, but I have no idea how to create a native 64-bit application. Your help would be greatly appreciated.

What architectures your application is built for depends on the Architecture field in your debian/control file.

  • all will build architecture-independent packages.
  • any will build architecture-depend packages, once for each of the supported architectures.

You can also explicitly specify the architectures that should be build (e.g. Architecture: amd64 armel).
