Windows 10 Prototype with Automake Build System

This is a prototype build system for ION on Windows 10. It is not yet thoroughly tested but released for wider experimentation.

Install MSYS2

  • Go to the MSYS2 GitHub repository at https://github.com/msys2/msys2-installer/releases
  • Expand the Assets list in the newest update block
  • Locate the installer executable (msys2-x86_64-<release-date>.exe). You can (and should) verify the hash and signature for the file.
  • Download and run the installer
  • The default location for the installation is c:\msys64
  • The installer will offer to “run MSYS” by opening a “UCRT64” shell when the installation is finished. Either uncheck the box or close this shell.

Note that the user home directory is located at “C:\msys64\home” if the default installation location was selected.

Open a MINGW64 bash shell & Install required packages

  • From command prompt, run C:\msys64\mingw64.exe - For ION to install correctly, you must be in the correct shell. Make sure the prompt includes “Mingw64" before proceeding.

  • Update base packages of MSYS2 with pacman -Syu

  • You may need to restart mingw64.exe and run pacman -Syu again to complete the update.

Install packages necessary to build ION

(autotools, mingw64_gcc, etc).

  • A script has been provided (mingw64_packages.sh) that should install everything needed.
  • You can look through the script to see the package list.
  • Another "backup" script mingw_packages_backup.txt that shows packages specifically for each shell (ex. Mingw_w64 gcc and Msys gcc are different, etc). Install only as needed. We recommend you start with using just the packages in mingw64_packages.sh script and try to build ION.

Build & Install ION

In the top directory of the ION source tree

Run autoreconf -fi

Run ./configure with the options you want. If you encounter errors/warnings during build regarding shared library due to "undefined symbol" by libtool, you can work around it by using static linking with the option --enable-shared=no.

Run make

Note: in mingw-w64, the make command is typically installed as mingw32-make.exe rather than just make, and MSYS2 doesn’t always create a make alias or symlink by default.

Check the directory /mingw64/bin to see if you have make.exe or mingw32-make.exe . If you have mingw32-make.exe then create a symbolic link to use make.

ln -s /mingw64/bin/mingw32-make.exe /mingw64/bin/make.exe

Run make install

ION is now ready for use; however, for killm to work correctly, the execution of scripts must be enabled in PowerShell:

  • Run Set-ExecutionPolicy RemoteSigned in PowerShell in order to enable the running of scripts.
  • Note that the “RemoteSigned” policy normally prevents downloaded scripts from running. Currently MSYS2 does not set the ZoneIdentifier meta-data, resulting in all ION files considered to be local. If that changes in the future, or ION was unpacked in Windows, you can use unblock-file .\remove_win_shmem.ps1 in PowerShell to remove the ZoneIdentifier.
