Hi all,
Basics OpenGL Remote display from a Solaris 8 to a Linux (Mandriva 2007.0, but
same behaviour with lots of other "guest" OSs) box fails at startup.
This is a February 2004 solaris, and some patches were installer as it is a CAD
machine with Catia and all the stuff.
Here is the log with a standard sun demo program,
[adm424 at scratchy ~]$ /usr/openwin/demo/GL/ogl_install_check

same error with the glxgears.
int attrib[] = { GLX_RGBA,
GLX_RED_SIZE, 1,
GLX_GREEN_SIZE, 1,
GLX_BLUE_SIZE, 1,
GLX_DOUBLEBUFFER,
GLX_DEPTH_SIZE, 1,
None };
int scrnum;
XSetWindowAttributes attr;
unsigned long mask;
Window root;
Window win;
GLXContext ctx;
XVisualInfo *visinfo;
scrnum = DefaultScreen( dpy );
root = RootWindow( dpy, scrnum );
visinfo = glXChooseVisual( dpy, scrnum, attrib );
//printf("depth: %d\n", visinfo->depth);
if (!visinfo) {
printf("Error: couldn't get an RGB, Double-buffered visual\n");
exit(1);
}
I remember I tried to play with attrib array values, but no way to make it work.
Is there any known workaround.
I'm sure there is since Catia v4 and Catia 4D Nav manage to work in remote, so
they must do tricky things ?
Thanks,
Benjamin.
