windows build

[extrawurst]

it seems we have troubles getting this to build for windows (see gitui-org/gitui#219). should it work? if so how? is it possible to add this to the projects CI for reference?

The main issue for this is now gpg-rs/gpgme#31. Note you shouldn't need to depend on this crate directly as it's re-exported by the gpgme crate.

I'm also having issues building this on Windows.

The build script seems to fail because it calls sh.

  --- stderr
  running: "sh" "-c" "C:\\Users\\timvisee\\scoop\\apps\\gnupg\\2.2.27\\bin\\libgpg-error-0.dll --version"
  failed to execute command: Os { code: 2, kind: NotFound, message: "The system cannot find the file specified." }
  Error: ()

Any comments on getting this to work?

That's slightly odd. Are you setting any of the LIBGPG_ERROR_* environment variables? Also which version of the crate are you using? One of the methods the build script uses to detect an installation of GnuPG is running a shell script that is distributed alongside GnuPG. The LIBGPG_ERROR_CONFIG environment variable controls the path used for this script, and if set (and neither LIBGPG_ERROR_LIBS or LIBGPG_ERROR_LIB_DIR are set) then it is the only method that is attempted. On windows if it is none of those are set, the build script attempts to retrieve the location of the installation from the registry (Install Directory in HKLM:\SOFTWARE\GnuPG). Finally, if that fails it attempts to run the configuration script using a default name (gpg-error-config).

Based on that output and the rules above, it appears that something set LIBGPG_ERROR_CONFIG to the location of the libgpg-error dll.
