Ok got it. I prefer PM because I don't want to look "silly", with my dump questions..
I've downloaded android-ndk-r20b-windows-x86_64, unzipped it, and rename the folder to "0", so directory is now "D:\Downloads\0".petero2 wrote: ↑Sun Jul 26, 2020 9:18 am but here are some more things I found out:
I also got crashes when using NDK r21d, so I used version r20b instead. I suspect this is related to the -fopenmp flag and I also suspect you only need this flag to run the training code, but I have not tested this.
For recent NDK versions you no longer need to create a standalone toolchain. You can run the compiler directly from the bin directory created when unpacking the NDK zip file, e.g. something like d:\android-ndk-r20b\toolchains\llvm\prebuilt\windows_something\bin. It may still work to create a standalone toolchain though, I have not tested that.
You don't need to change the Makefile when using your bat file because it is invoking the compiler directly so the Makefile is not used.
First i created standalone toolchain, it didn't work, i got this errors.
