I attempted to get OSG to compile in Cygwin and I finally got an X11
version to compile. I had problem with osgViewer which did not seem to
want to add the libraries X11 and Xrandr even though it saw them. I
could add the libraries to link.txt for the modules that failed and
then execute and they would compile. I tried determining what was
wrong with the CMakeLists.txt for osgViewer but only way I could get it
to add the X11 and Xrandr was to change this routine near the end:
IF(MINGW OR CYGWIN)
SET(TARGET_EXTERNAL_LIBRARIES ${TARGET_EXTERNAL_LIBRARY} gdi32 )
ENDIF()
so that the set line reads as follows:
SET(TARGET_EXTERNAL_LIBRARIES ${TARGET_EXTERNAL_LIBRARY} gdi32
${X11_X11_LIB} ${X11_Xrandr_LIB} )
And then compiled great and worked.
I then tried to get it to compile without X11 by setting
OSG_WINDOWING_SYSTEM to none and it compiled but osgViewer could not
create a window so then I change the GL references to point to the
opengl libs in w32api for cygwin which as I recall is the appropriate
think to do so it uses the win opengl libs and includes. But now when
compiling I get this error regarding GLfloat and GLdouble
