[vbox-dev] is 2D/3D acceleration supported in OSE?

[Huihong Luo]

(sorry, last email was sent accidently)
 
I found the problem,
 
in process-win.cpp
 
RTR3DECL(int) RTProcCreate(const char *pszExec, const char * const *papszArgs, RTENV Env, unsigned fFlags, PRTPROCESS pProcess)
{
 
HANDLE hProcess = (HANDLE)_spawnve(_P_NOWAITO, pszExec,  papszArgs, papszEnv);
 
the 1st argument of  papszArgs needs to be quoted if containing space
 
}
 
// test app

// spawnve.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <windows.h>
#include <process.h>
int _tmain(int argc, _TCHAR* argv[])
{
static char pszVBoxPath[MAX_PATH];
const char *papszArgs[] = { NULL, "-test", "2D", NULL};
strcpy(pszVBoxPath, "c:\\bugs\\Sun VirrtualBox\\VBoxTestOGL.exe");
papszArgs[0] = "\"c:\\bugs\\Sun VirrtualBox\\VBoxTestOGL.exe\""; //pszVBoxPath; /* argv[0] */
HANDLE hProcess = (HANDLE)_spawnve(_P_NOWAITO, pszVBoxPath, papszArgs, NULL);
WaitForSingleObject(hProcess, INFINITE);
return 0;
}

Thanks for the investigation. I'll debug it here on my side, although I'm sure it works here when installed under C:\Program Files\Sun\VirtualBox\, i.e. path with spaces.
Re your second question: yes, it always use OpenGL currently even on windows hosts. 
This allows making a unified cross-platform engine for 2D acceleration that works on Linix and Mac hosts as well.
Perhaps someday in the future we'll have a DirectX-based backend for windows.






yes, it's XP guest on Vista host.
 
I debugged a bit, the invocation of VBoxTestOGL.exe, (for example, in following code)
 
bool VBoxVHWAInfo::checkVHWASupport()
 
always exit with status 1 (monitored by procmon.exe) if the path contains a space. Works well after removing the space, exits 0.
 
If I just invoke VBoxTestOGL.exe from command line by hand, e..g
 
"VBoxTestOGL.exe -test 2D" it works even from a path with spaces
 
another question, since this test exe checks OpenGL, does that mean the acceleration always uses OpenGL even on windows host where DirectX is available?
 
Thanks,

Which host platform are you running on?


 Huihong Luo usually runs Windows-on-Windows.
