Introduction to GPGME

The GPGME package is a C library that allows cryptography support to be added to a program. It is designed to make access to public key crypto engines like GnuPG or GpgSM easier for applications. GPGME provides a high-level crypto API for encryption, decryption, signing, signature verification and key management.

This package is known to build and work properly using an LFS 11.3 platform.

GPGME Dependencies




Doxygen-1.9.6 and Graphviz-7.1.0 (for API documentation), GnuPG-2.4.0 (required if Qt or SWIG are installed; used during the test suite), Clisp-2.49, Qt-5.15.8, and/or SWIG-4.1.1 (for language bindings)

User Notes:

Installation of GPGME

First, fix an issue building with Python 3.11 installed:

sed -e 's/3\.9/3.11/'                    \
    -e 's/:3/:4/'                        \
    -i configure

Apply a patch to fix build failure with SWIG and libgpg-error-1.46 or later:

patch -Np1 -i ../gpgme-1.18.0-gpg_error_1_46-1.patch

Install GPGME by running the following commands:

./configure --prefix=/usr --disable-gpg-test &&

To test the results, you should have GnuPG-2.4.0 installed and remove the --disable-gpg-test above. Issue: make -k check.

Now, as the root user:

make install

Command Explanations

--disable-gpg-test: if this parameter is not passed to configure, the test programs are built during make stage, which requires GnuPG-2.4.0. This parameter is not needed if GnuPG-2.4.0 is installed.
