Project doesn't seem to be working for main OSs

[luizperes]

It seems that simd_nodejs on the master branch is only currently working for Linux (the current tag version 0.0.2 on npm has only been tested with Mac and seems to be fine.

At the moment, we have two reported error in Windows and Mac:

• Windows: Windows build failure on outdated node-gyp (msvs_version=2015) @ Windows 7 x64 #1
• Mac: (see output below)

It seems that the flags __AVX2__ and BMI are not being recognized on Mac OS (it was tested outside npm and runs fine)

[luizperes]

Here goes a list of the tested OSs. for current npm version 0.0.3:

• Linux
• Mac OS
• Windows

[luizperes]

Help needed for windows, removing that from WIP since I don't have a windows machine

[lemire]

This may get resolved with the next version of simdjson. Upstream, simdjson will provide runtime dispatch.

Hi @lemire, I still need help for testing if it is working on Windows. For this reason I won't close it right now, cheers!
