Windows

The Windows release is created on Linux using cross compilation. The release is built with ./release.sh windows-amd64, which runs the Go cross compiler in the fstab/grok_exporter-compiler-amd64 Docker image.

Continuous integration for Windows is run on AppVeyor as configured in .appveyor.yml.

However, if Windows tests fail it is sometimes useful to reproduce this locally in a Windows VM. The following describes how to set up a Windows 10 VM on VirtualBox for running Windows tests locally.

• Create a Windows 10 Home Edition VM using the official ISO from https://www.microsoft.com/software-download/windows10. You don't need a license key to do that. I used 8G RAM and 60G disk, but that might not be necessary.
• Install Go as an MSI from https://golang.org/ and add C:\Go\bin to your PATH.
• Install msys2-x86_64 from https://www.msys2.org.
• Run the mingw64 shell in the msys2 terminal by double-clicking C:\msys64\mingw64.exe.
• The following steps must be performed in the msys2 terminal:
  • Repeatedly run pacman -Syu until all packages are up-to-date.
  • Run

    pacman -S base-devel \
              mingw-w64-i686-toolchain \
              mingw-w64-x86_64-toolchain \
              git \
              mingw-w64-i686-cmake \
              mingw-w64-x86_64-cmake
    

  • Download the latest oniguruma release from https://github.com/kkos/oniguruma/releases and install it as follows (replace 6.9.2 with the current version):

    tar xfz onig-6.9.2.tar.gz
    cd onig-6.9.2
    ./configure --host=x86_64-w64-mingw32 --prefix=/C/msys64/mingw64
    make
    make install
    

  • Clone grok_exporter from https://github.com/fstab/grok_exporter. Build and run it as follows:

    git clone https://github.com/fstab/grok_exporter.git
    cd grok_exporter
    git submodule update --init --recursive
    alias go=/C/Go/bin/go
    go fmt ./...
    go vet ./...
    go test ./...
    go install
    

    This will create grok_exporter.exe in C:\Users\...\go\bin\.
