Hi,
I was updating the Debian package for Mesa and I want to make sure I'm
not going to mess up things. In Debian there are several Mesa packages
available: the ones from the mesa source (the "regular" mesa, a glide2
package, a ggi package, plus a development package) and the ones coming
from the XFree86 sources (the "regular" mesa, xlibmesa3[1], a
development package, xlibmesa-dev, and a OSMesa package). The 3.2
packages still have some libMesaGL -> libGL symlinks which I'm going to
remove in the 3.4 package (or 3.4.1). What I'm not sure what to do
with is the libMesaGLw library. The xlibmesa-dev package provides
libGLw.a, which contains the following symbol definitions:
GLwDrawingAreaMakeCurrent
GLwDrawingAreaSwapBuffers
glwDrawingAreaClassRec
glwDrawingAreaWidgetClass
glwMDrawingAreaClassRec
glwM1DrawingAreaWidgetClass
glwM2DrawingAreaWidgetClass
GLwCreateM1DrawingArea
GLwCreateM2DrawingArea
glwMDrawingAreaClassRec
which is slightly different from what's generated using the sources in
widgets-mesa.
The other difference is the name of the library itself. mesa generates
libMesaGLw and libMesaGLwM, depending if the Motif version of the
widgets is enabled or not. This library also provides the "mesa"
functions (e.g., mesaDrawingAreaClassRec).
My problem with all of this is that the the "xfree86" packages provide
libGLw.a as part of the aforementioned xlibmesa-dev package, which
means the mesag-dev[2] package has to provide this file in some
(compatible) way.
One possible solution for me is to just ask the XFree86 maintainer to
split the widgets out of the xlibmesa packages and don't use the ones
provided by the mesa source. The other one is to ask you guys to use
the SI source for the widgets. Yet another one is to do that myself
(but I'm not too fond of that idea). Another one is the included
patch, which only modifies the widgets-mesa/src/Makefile in order to
generate a libGLw.a library which has the same stuff as the "xfree86"
library (modulo the Motif 1/Motif 2 functions). Please note the motif
library is still called libGLwM.a.
Thank you in advance for your input,
Marcelo
[1] If you are asking yourself about this name, that makes two of us.
[2] the "g" is a remanent of past times, when there was a mesa-dev
package that provided a libc5 development environment.
