Hi, I’m sorry to complain, but I have about 75 to 100 errors while building UE4 with Nvidia Physx Flex. I’m using VS2017, with the 2015 toolkit, the Flex branch is 4.19, but I also tried 4.17 and both end up with the same problems. I also tried to build it with vs2015, and still no success. I also tried to build a clean UE4 release version and it builds itself without any error/warning. I have also changed VC++ Directories to inherit from the parent. but it only decreased the number of errors from 150 to 75. I will be super glad if someone would be able to help me with it. Below I print the screen of some errors.
