libgdata is a GLib-based library for accessing online service APIs using the GData protocol — most notably, Google's services. It provides APIs to access the common Google services, and has full asynchronous support.

See the test programs in gdata/tests/ for simple examples of how to use the code.

libgdata is API and ABI stable.

• glib-2.0 ≥ 2.44.0
• libxml-2.0
• gio-2.0 ≥ 2.44.0
• libsoup-2.4 ≥ 2.42.0
• liboauth ≥ 0.9.4
• json-glib ≥ 0.15.0

If compiling with --enable-gnome (for GNOME support):

• gcr-base-3
• goa-1.0 ≥ 3.8

If compiling the demos:

• gtk+-3.0 ≥ 2.91.2

If the environment variable LIBGDATA_DEBUG is set to one of the following values, libgdata will give debug output (at various levels):

• 0: Output no debug messages or network logs
• 1: Output debug messages, but not network logs
• 2: Output debug messages and network traffic headers
• 3: Output debug messages and full network traffic logs, redacting usernames, passwords and auth. tokens
• 4: Output debug messages and full network traffic logs, and don't redact usernames, passwords and auth. tokens

If LIBGDATA_DEBUG is unset, no debug output will be produced.

So, to debug a program which uses libgdata, run it from a terminal with the following command:

LIBGDATA_DEBUG=3 ./my-program-name &> libgdata.log

If LIBGDATA_DISABLE_DEPRECATED is defined when compiling against libgdata, all deprecated API will be removed from included headers.

The default development branch of libgdata has been renamed to main. To update your local checkout, use:

git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
