Erik,
Here are some of the references to EXTGL_NEEDED in the SimGear root
directory:
-- configure.ac:
AM_CONDITIONAL(EXTGL_NEEDED, test "x$ac_cv_header_windows_h" = "xyes")
-- configure:
if test "x$ac_cv_header_windows_h" = "xyes"; then
EXTGL_NEEDED_TRUE=
EXTGL_NEEDED_FALSE='#'
else
EXTGL_NEEDED_TRUE='#'
EXTGL_NEEDED_FALSE=
fi
-- config.log:
EXTGL_NEEDED_FALSE='#'
EXTGL_NEEDED_TRUE=''
-- Makefile:
EXTGL_NEEDED_FALSE = #
EXTGL_NEEDED_TRUE =
And in SimGear/simgear/sky/clouds3d/Makefile:
EXTGL_SOURCE = extgl.c extgl.h
#EXTGL_SOURCE =
libsgclouds3d_a_SOURCES = \
$(EXTGL_SOURCE) \
vec3fv.cpp vec3fv.hpp vec3f.hpp vec4f.hpp vec2f.hpp \
... etc.
extgl.h is #include'd by SkyTextureState.cpp via SkyTextureState.hpp via
SkyContext.hpp. It looks like all the ifdef's are working properly. So I
am stumped here - why can't the compiler see the declaration of
glActiveTextureARB() when compiling SkyTextureState.cpp? I'm missing
something.
