Another issue with the latest srsieve2:
from 14.06. Code:

I tried your file.
I have to copy the CL folder to mtsieve for it to compile. gcwsievecl still crashes. Last fiddled with by Citrix on 20200621 at 23:17

I downloaded the latest version of mtsieve and compiled it. gcwsievecl.exe does work and did not crash.
The cl code is not working properly. I will play with it and let you know. The make file for version 1.94 is not properly configured for GPU compiling.

Originally I had only one exe, which works for most people even if they didn't or couldn't use the GPU code, but some had issues because at runtime it would look for GPU related libraries even if they were not using GPU workers. For example, there is now App_cpu.o and App_gpu.o. App.cpp is used to build both, but a compiler switch will build different objects.
