Check your CSF_GraphicShr environment variable. It should point to TKOpenGl.dll.

The environment variable CSF_GraphicShr is correctly set.

And when I replace the TKernel.dll with the original one, some samples will run.

Hi Tom,

recompile the samples and try it again!

How to check CSF_GraphicShr environment variable and how to set it?

Patrik Mueller's picture

Hi,

here are 2 methods I use for environment variables:

void Im_AppHelper::SetEnvironmentVariable(const TCollection_AsciiString& myVarName, const TCollection_AsciiString& myVarValue)
{
OSD_Environment myEnv;
myEnv.SetName(myVarName);
if (myEnv.Value() == "")
myEnv.SetValue(myVarValue);

}

TCollection_AsciiString Im_AppHelper::GetEnvironmentValue(const TCollection_AsciiString& myVarName)
{
OSD_Environment myEnv;
myEnv.SetName(myVarName);
return myEnv.Value();
}

HTH,

Patrik

I have tried your method and use
myEnv.SetValue(myVarValue) to set my OpenGl.dll path, but the valiable is still"C:\OpenCASCADE5.1\ros\win32\dll\TKOpenGl.dll".why?
thx.

Patrik Mueller's picture

If the variable is already set I work with the old one (look at the source). And "TKOpenGL.dll" isn't the same as "OpenGL.dll"!!!!!

Hi everyone,

I also got the same error "FATAL ERROR DURING GRAPHIC INITIALIZATION" when I am building the OCC environment. But when I run the example it works. This error don't have much effect on the OCC setup.
