Hi Fred, James,
Well, I think the -DNO_OPENSCENEGRAPH_INTERFACE=1
needs to be applied to ALL ports, since terragear-cs
should have no need for OpenSceneGraph dependence,
IN ANY MACHINE...
It seems -DNO_TIMER is due solely to a file
as part of -
src/Lib/TriangleJRS/triangle.c
for systems that do NOT have the function
'gettimeofday()', and that is just native Windows,
no?
And maybe mingw? Or cygwin? - do not know...
In my previous TG Windows build I added -
#define NO_TIMER
#define TRILIBRARY
to a hand crafted config.h for MSVC...
and added -
#include config.h
to triangle.c...
But now that cmake generates a 'config.h' in
ALL platforms, then perhaps it could be added
to that rather than as yet ANOTHER compiler
switch...
Or perhaps dealt with like TRILIBRARY, in
src/Lib/TriangleJRS/CMakeLists.txt
set_target_properties(TriangleJRS PROPERTIES
COMPILE_DEFINITIONS TRILIBRARY )
Although, really, it would NOT be a big job to add
a gettimeofday() service, either using the native
QueryPerformanceCounter(&li)
or even _ftime(), for the Windows port...
That could be as simple as -
#ifdef _MSC_VER
#include <sys\timeb.h>
#ifndef timeval /* is in Ws2_32.h */
struct timeval {
long tv_sec;
long tv_usec;
};
#endif /* timeval */
#ifndef timezone
struct timezone {
int tz_minuteswest;
int tz_dsttime;
};
#endif /* timezone */
int gettimeofday(struct timeval *tp, void *tzp)
{
struct _timeb timebuffer;
_ftime(&timebuffer);
tp->tv_sec = timebuffer.time;
tp->tv_usec = timebuffer.millitm * 1000;
return 0;
}
#endif /* _MSC_VER */
Just tested this code in Windows, and it compiles
fine, making no need to define NO_TIMER for
Windows ;=))
Had to change one other line -
#ifndef NO_TIMER
to
#if !defined(NO_TIMER) && !defined(_MSC_VER)
#include <sys/time.h>
#endif /* NO_TIMER */
HTH.
Regards,
Geoff.
