MSYS configuration script #427

Closed maxirmx closed 2 years ago

maxirmx commented 2 years ago

Hello @ribose-jeffreylau This PR includes the working windows configuration script. There were several issues, not only ACLOCAL path

HOWEVER, that was a minor problem. If you now look at build errors you will see that RTLD_NEXT is not defined. dlsym with RTLD_NEXT option is the hooking method that dtrace uses. It is not a part of POSIX and it is not available in MSYS. Frankly speaking, I have no idea (yet) how to fix it in reasonable time.

Windows has system call that provides for similar implementation -- SetWindowsHookEx https://docs.microsoft.com/en-us/windows/win32/winmsg/using-hooks

There is mingw package that pretends to be a wrapper
https://packages.msys2.org/package/mingw-w64-x86_64-dlfcn but it is mingw and thus requires windows toolchain that can not support other retrace features
