Charm++ parallel programming system

[Evan Ramos <evan AT hpccharm.com>]

Hi Gerardo,

Charm++ supports building with GCC on Windows through MSYS2, but not Cygwin or the original MSYS. You can install MSYS2 from: https://www.msys2.org/

Once installed and fully updated, run `pacman -S mingw-w64-x86_64-{toolchain,cmake} make autoconf automake git` to install the necessary dependencies. Then, open the MSYS MinGW 64-bit shortcut (not 32-bit or "MSYS2 MSYS") to get a prompt capable of building Charm.

We would recommend using the latest code from our Git repository: https://github.com/UIUC-PPL/charm.git

The build command would be: ./build charm++ multicore-win-x86_64 gcc

Regards,

Hi!

I started to compile charm++ under windows10, using gcc. In both Msys/Mingw and cygwin, I got the same error:

Can you help me?

Thanks before hands and best wishes,
