2 Wayland Support for FLTK

On Linux and FreeBSD systems, the FLTK library is by default configured so FLTK apps

do all their windowing through the Wayland protocol, all their graphics with

Cairo or EGL, and all text-drawing with Pango. If no Wayland compositor is

|
||||
2.1 Configuration
|
||||
------------------
|
||||
|
||||
2.1.1 Configure-based build can be performed as follows:
|
||||
Once after "git clone", create the configure file :
|
||||
autoconf -f
|
||||
On Linux and FreeBSD systems equipped with the adequate software packages
|
||||
(see section 4 below), the default building procedure produces a Wayland/X11
|
||||
hybrid library. On systems lacking all or part of Wayland-required packages,
|
||||
the default building procedure produces a X11-based library.
|
||||
|
||||
Prepare build with :
|
||||
./configure --enable-wayland
|
||||
Add --disable-x11 to build FLTK for Wayland-only (no x11 backend).
|
||||
Use -DOPTION_USE_WAYLAND=OFF with CMake or "configure --disable-wayland" to build
|
||||
FLTK for the X11 library when the default would build for Wayland.
|
||||
|
||||
Build with :
|
||||
make
|
||||
|
||||
2.1.2 CMake-based build can be performed as follows:
|
||||
cmake -S <path-to-source> -B <path-to-build> -DOPTION_USE_WAYLAND=1
|
||||
|
||||
cd <path-to-build>; make
|
||||
CMake OPTION_WAYLAND_ONLY or "--disable-x11" configure argument can
|
||||
be used to produce a Wayland-only library which can be useful, e.g., when
|
||||
cross-compiling for systems that lack X11 headers and libraries.
|
||||
|
||||
The FLTK Wayland platform uses a library called libdecor which handles window decorations
|
||||
(i.e., titlebars, shade). Libdecor is bundled in the FLTK source code and FLTK uses by default
|
||||
this form of libdecor. Optionally, OPTION_USE_SYSTEM_LIBDECOR can be turned on to have FLTK
|
||||
this form of libdecor. CMake OPTION_USE_SYSTEM_LIBDECOR can be turned on to have FLTK
|
||||
use the system's version of libdecor which is available on recent Linux distributions (e.g.,
|
||||
Debian Bookworm or more recent in packages libdecor-0-0 and libdecor-0-plugin-1-cairo).
|
||||
|
||||
Optionally, OPTION_WAYLAND_ONLY can be turned on to build FLTK for Wayland-only (no x11 backend).
