Libgpg-error is a small library that originally defined common error values for all GnuPG components. Among these are GPG, GPGSM, GPGME, GPG-Agent, libgcrypt, Libksba, DirMngr, Pinentry, SCdaemon. Because Libgpg-error is a common dependency all GnuPG components, more features have been added to the library:

• An extended stream library (estream) which for example allows the use of memory or cookie based streams.
• A printf implementation to provide a uniform interface on all platforms. This also includes asprintf style functions.
• An implementation of locks (mutexes).
• A gettext implementation for use on Windows
• A Base64 decoder

This library will eventually be renamed to Libgpgrt to reflect that this is a runtime library for GnuPG and other software which likes to use it. The latest version already comes with a header file "gpgrt.h" which can be used instead of "gpg-error.h".

See the download section for the latest tarball.

The development takes place in a Git repo:

git clone git://git.gnupg.org/libgpg-error.git
