Hello,

the make - process is very slow in the msys environment in Windows. I think it is because it uses fork() which is not available in windows, and the emulation takes very long.

I know the alternative of using a virtual machine but does anyone have any workarounds to make it faster on Windows?

Thanks

Have you tried parallel jobs make -j5

As it happens, yesterday (git revision 16ef01d) some fixes were merged to the master branch improving Windows support, which includes a speed boost. Turns out running 'git submodule status' on Windows/MSYS2 is very slow, and the old build process ran this command multiple times each time 'make' was invoked.

Windows is still slower than Linux & OSX, I think fork() is a major reason for that. But since 16ef01d it should be less painfully slow.

As suggested, running parallel make (-j) also makes a big difference (across all platforms) if you have more than one CPU.
