You will need to make sure you have VS setup for x64.

I assign the machine to X64, and it works. However, another problem pops up in project Ping and PingPong:
hdr_histogram_static.lib(hdr_histogram.obj) : error LNK2019: unresolved external symbol __imp_floor, referenced in function hdr_calculate_bucket_config

Ping.cpp:
hdr_histogram *histogram; hdr_init(1, 10 * 1000 * 1000 * 1000LL, 3, &histogram);

Release is OK, the problem occurs on Debug.

This appears to be a problem with hdr histogram specifically (fortunately I maintain that too). What version of windows are you running?

[LaughingAngus]

I'm running windows 10 professional, 1903.
