4 years ago Hello, Can you provide more information about your system settings to help us understand the problem? We have provided detailed requirements on CMake and OS in https://github.com/LNIS-Projects/OpenFPGA/blob/master/README.md. It looks like you are using Windows. Are you using GCC or VS?
- If you are using GCC, make sure that your GCC version is 8+. Our continuous integration is using GCC 8.2.0.
- For VS, some flags may not be applicable. You find the setup in our CMAKE script https://github.com/LNIS-Projects/OpenFPGA/blob/0cfb88a49f152aab0a06f309ff160f222bb51ed7/CMakeLists.txt#L76 I hope that can help you. Best regards, Xifan Tang

I try to build OpenFPGA, and cmake has a error result, this is content of the CMakeError.log file:
Performing C++ SOURCE FILE Test CXX_COMPILERSUPPORTS-Wcast-allign failed with the following output: Change Dir: /home/lab601/桌面/OpenFPGA-master/build/CMakeFiles/CMakeTmp

Source file was: int main() { return 0; }
is the command line '-Wcast-allign' wrong? Or maybe the version of the compiler isn't right?
