gtkglarea-1.2.3: description + notes
GtkGLArea is an OpenGL widget for GTK+ GUI toolkit. The
gtkglarea
home page has more details.
Just as GTK+ is build on top of GDK, GtkGLArea is built on top
of gdkgl which is basically wrapper around GLX functions.
The widget itself is derived from GtkDrawinigArea widget and adds
only few extra functions.
Some sample programs are installed in
/usr/freeware/doc/gtkglarea. See the README
file in that directory for instructions. They are:
- gdkfont -- a font viewer.
- glpixmap -- show GL rendering to pixmaps.
- gtkglarea_demo -- a well commented example program.
- viewlw -- view LightWave 3D objects.
- zktor -- a simple game.
NOTE: Developers intending to use this distribution
for application development should be sure to read the information
below. Users installing it for the runtime environment only need
not read any further.
Developers intending to use this library for development of other
freeware packages or their own software applications will need to be
familiar with a few peculiarities due to the way that this library is
packaged and installed. The reasons for this installation strategy
are described further in the fw_common product release notes.
The header files and libraries in this package are installed into
/usr/freeware. This means that when building software using
this distribution you should be sure to do the following:
-
Include the following flag on your compile lines:
- -I/usr/freeware/include
This flag will cause your compilations to correctly find the library's
header files at compile time.
Include the following flag on your link lines:
-L/usr/freeware/lib32 (if using n32 ABI)
-L/usr/freeware/lib64 (if using 64 ABI)
This flag will cause the linker to correctly find the library's
archive or shared object files at link time.
Additionally, include the following flag on your link lines:
-rpath /usr/freeware/lib32 (if using n32 ABI)
-rpath /usr/freeware/lib64 (if using 64 ABI)
This flag will allow the binary to locate the shared object library
files when the application is run. This is required since the shared
objects are stored in these /usr/freeware subdirectories which
are not searched by the run-time linker by default.
Finally, if you are building an installable package for inst
(contributing to freeware, for example) be sure to make your package
depend upon this package. Add the following line to your spec
file:
prereq ( fw_gtkglarea.sw.lib 1270000000 1289999900 )
Following these guidelines will allow your application to safely and
easily use the software in this package.
To auto-install this package, go back and click on the respective install icon.
