• BuildingFromGIT
• Building GnuPG 2.1: GnuPG 2.1 is the latest GnuPG version but as with all 2.x versions it has several dependencies, which make building it a bit more difficult. Here are some notes.
  • Building for Unix
  • Building for Windows
  • Building for Android
• API checker: Upstream-Tracker.org checks ABI/API changes for some libraries like gpgme, libgpg-error, libgcrypt.

Note that the tools can't necessary decide whether something is an ABI or API change. The output should be used as a hint to look for whether there might be a problem. We are not aware of any broken API or ABI contracts for the listed libraries.
