| #5720 | obsolete | Opengl Texturing fails in 3.1.0 | ||
| Description |
Calling glTexImage2d produces the following errors: OpenGL Warning: vboxCall failed with VBox status code -54 OpenGL Warning: SHCRGL_GUEST_FN_WRITE_READ (28017464) failed with ffffffdb ffffffea An example of the code I'm using:
glBindTexture(GL_TEXTURE_2D, mTextures[0]);
next = VideoLayer::getImage(concat.str().c_str());
concat.str("");
if (next == NULL) return false;
GLint nOfColors = next->format->BytesPerPixel;
GLenum tFormat;
if (nOfColors == 4)
{
if (next->format->Rmask == 0x000000ff)
tFormat = GL_RGBA;
else
tFormat = GL_BGRA;
}
else
{
cerr << "image is not truecolor...\n";
return false;
}
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST_MIPMAP_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST_MIPMAP_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);
cerr << "reading texture" << endl;
glTexImage2D(GL_TEXTURE_2D, 0, nOfColors, next->w, next->h, 0,
tFormat, GL_UNSIGNED_BYTE, next->pixels);
cerr << "read" << endl;
SDL_FreeSurface(next);
glGenerateMipmapEXT(GL_TEXTURE_2D);
Host System: Windows 7 64-bit Guest System: Ubuntu 9.10 64-bit This code works perfectly both under the Windows host and under the same Ubuntu guest running Vbox 3.0.12. The program continues to run past these errors, but all textures appear white. All other opengl functions seem to work fine despite the errors with texturing. |

Hi!

| #5738 | obsolete | Error in opening a USB flash drive in "Devices" of Virtual Box guest of Windows Vista host | ||
| Description |
When trying to open a USB flash drive in the Devices menu item of a VirtualBox guest of a Windows Vista Host one gets the following message:
In short, VirtualBox is unable to capture USB device. I suspect that the reason can be found in item 3.10 of the VirtualBox "Help":
However, since Windows Vista does NOT allow kernel mode device drivers, I suspect that USB support is being broken by Vista blocking the loading of the driver.
