Compilation error with MSVC compiler

[chetan-sadhu]

When trying to compile with Microsoft Visual Studio 2017 compiler with USE_OPEN_MP = ON, we get Compiler Error C3016 because OpenMP for loops uses std::size_t as a the datatype for loop index.

As a work around, I edited the datatype to long long instead of size_t which is unsigned long long and I am not sure if this is correct.

Hi @chetan-sadhu
we currently don't have the resources needed to support Windows OS. However, if you are confident with your workaround, don't hesitate to submit a PR and update the Windows guide accordingly!
Alternatively, you can also build and run libpointmatcher in WSL which should work seamlessly.
