RTresult code = rtProgramCreateFromPTXString(context, pBuf, "draw_solid_color", &ray_gen_program);

The code result is 

RT_ERROR_INVALID_SOURCE

My project can generate PTX file, and the cuda and optix are configured.

How can I resolve this problem?

1) Make sure the string pBuf points to is well formed and null-terminated 2) Check the PTX bitness (should probably be 64 from now on) 3) No debug info in the PTX - Marco A.
