Thanks for reporting this!
The issue seems to be

src/distance.cpp:18:46: error: call of overloaded ‘abs(double)’ is ambiguous
result[ax*awidth + bx] = abs(a[ax] - b[bx]);

however I can't reproduce this on Ubuntu 18.04. I believe it is either caused by a different version of GCC or a different version of some library.

Could you share the following information?

Output of gcc -v
Which distribution & version of that distribution you are using (e.g. "Debian Jessie")?

I'm convinced it's a pretty easy fix, but I need to be able to reproduce it somehow.

@mekacharan @GeorgeKaspar I've added an explicit cast to int64_t to try to resolve this issue. Can you retry the pip install command (if you cloned the repository instead of using git+https://... with pip, you might need to git pull before that)?

@vtatntpt
Your issue seems to be different. You are missing stdlib.h - I recommend to Google for "msvcc stdlib.h not found" and try out some of the solutions suggested there. It's not specifically an issue with cv_algorithms, however maybe if you could share what worked for you we might be able to provide that solutions to other users

Uli Köhler · Answer 9 · Sat Aug 03 2019 21:38:00 GMT+0800 (China Standard Time)

@Others
Although I couldn't spend any time on the popcount issue before, I am still aware of it and will try to find a solution.

Based on https://stackoverflow.com/a/24550632/2597135 I have implemented a solution for Microsoft compilers.

Could you check on your platform?

Unfortunately, the error message is still the same:
src/popcount.cpp(46): error C3861: "__builtin_popcountll": Bezeichner wurde nicht gefunden. error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

@CrazyCrud Thanks for checking.This seems to be a different error message. Now it's complaining about __builtin_popcountll (long long version).

I have just commited a possible fix, could you try again?

@ulikoehler No problem.
I tried to install it with the new fix, but another error occured:
LINK : error LNK2001: Nicht aufgelöstes externes Symbol "PyInit__cv_algorithms". build\temp.win-amd64-3.6\Release\src\_cv_algorithms.cp36-win_amd64.lib : fatal error LNK1120: 1 nicht aufgelöste Externe error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x64\\link.exe' failed with exit status 1120

This one seems related with #4

I've just released a fix for the Windows installation problem, could you please check if the issue persists?
