Compiling with libhandy

Compiling with libhandy — Notes on compiling

Using pkg-config

Like other GNOME libraries, libhandy uses pkg-config to provide compiler options. The package name is "libhandy-0.0". So in your script, you might specify something like:


Or if using Meson/Ninja use a dependency('libhandy-0.0') dependency.

The "0.0" in the package name is the "API version" (indicating "the version of the libhandy API that first appeared in version 0.0") and is essentially just part of the package name.

When using the Meson build system you can declare a dependency like


Acknowledge the Instability

Since the library is young and is still changing a lot, in order to use it you are required to acknowledge that your are using an unstable API. To do so, HANDY_USE_UNSTABLE_API must be defined for compilation to succeed.

From C code or any compatible language, you can prefix your inclusion of the libhandy header like so:

#include <handy.h>

Including individual headers rather than handy.h is not recommended.

You can also acknoledge this with the definition option of your C compiler, like -DHANDY_USE_UNSTABLE_API. This is required from Vala.

To use libhandy from Vala, you must define the acknowledgment in C via -X -DHANDY_USE_UNSTABLE_API. If your build system uses a two pass compilation and hence your Vala compiler outputs C (Meson, Automake, or using the --ccode Vala compiler option trigger that) then you must add -DHANDY_USE_UNSTABLE_API to your C compiler argments instead.
