Hello everyone. I am following the steps for Windows here but for some reason I cannot build thundersvm.

I have the following: CMake - 3.16 Visual Studio Community - 16, 2019 CUDA - 10 gcc (MinGW.org GCC-6.3.0-1) 6.3.0

edit: made the output more readable

Any ideas? What should I look into? Thanks in advance

Hi, @AHarardLeap

Have you changed the instruction in the doc to cmake .. -DCMAKE_WINDOWS_EXPORT_ALL_SYMBOLS=TRUE -DBUILD_SHARED_LIBS=TRUE -G "Visual Studio 16 2019 Win64" ? Also, there is a link that may be helpful.

Hello @GODqinbin , yes I have. I successfully installed thundersvm in another computer so now I'm wondering if there are instructions how to do a clean reinstall because I might have made a mistake the first time.

Hi, @AHarardLeap

If you are using Windows, you can just delete the thundersvm directory to remove it.
