hello
I am getting the following errors when I install liboqs on windows with mingw32.

$ ninja -j 4

what i see is that the mingw32 can not find the __rdtsc() function.
i am searching in the internet and find the library intrin.h which has this function.
i think this library is missing in the ds_benchmark.h.
Thank you in advance!

This is a discussion board for general OQS-related items; project & platform-specific issues should be discussed there: Please transfer this to a liboqs issue.

i think this library is missing in the ds_benchmark.h.

Have you validated that by adding the corresponding #include statement? If so, please consider doing a PR, ideally in combination with a mingw32 CI test case.

[k-Artin]

after adding the library this error will be disappear.
the discussion transfered to a liboqs issue.
