Hello @starrychloe,

Currently there is no upstream support for v8 compilation under Cygwin or MinGW. The only official support build for Windows is with MS VS 2008 and the compiled library cannot be used with Cygwin and MinGW.

We are currently working on cross-compilation support for arm which will pave the way to eventual Windows support. We hope we will be able to eventually release Windows binaries (MinGW first) and the best case scenario will be to enable native compilation. However while there is little to no modification of the GYP scripts necessary for ARM as it is officially supported by v8, MinGW and Cygwin support have to be implemented from the ground up.

P.S. Needless to say any help with this will be appreciated.
