Setup windows toolchain
Instruction (can be added into README.md also)
To build go-spacemesh on Windows all you need is Msys2
- Install msys2 from https://www.msys2.org/ and update it. Update is not necessary but strongly recommended, for update you can do next:
- Run Msys2 shell (press Win-key once and type msys2)
- Update msys base
pacman -Syu --noconfirm
- Run Msys2 shell again if it closed after update (it's OK)
- Update msys
pacman -Su --noconfirm
- To setup windows toolchain run Msys2 shell and and do next:
- Install git and make
pacman -S git make --noconfirm
- Clone go-spacemesh repo
git clone https://github.com/spacemeshos/go-spacemesh
- Go to go-spacemesh folder
cd go-spacemesh
- Run once
make setup-windows-toolchain
- To build go-spacemesh run Msys2 shell and do next:
- Clone/Checkout required go-spacemesh branch
- Run
make
in the go-spacemesh folder
Do not forget install VisualC++ runtime if you don't have it installed. It's used by gpu-setup.dll https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist
Motivation
Build apps with CGO on Windows is not trivial so this PR adds target into the Makefile to setup build environment.
Closes #2626
Changes
It adds new target setup-windows-toolchain
to setup windows go/gcc toolchain.
This sounds similar to my manual Win 10 pro setup. I'm going to try the instructions on a windows 10 pro machine and provide feedback as soon as I'm able to do so.
I've followed the instructions and it mostly works - I was able to build ok on win 10 pro with some caveats. See below.
- Install msys2 from https://www.msys2.org/ ad update it. Update is not necessary but strongly recomended:
- I assume you update it using the instructions you provide below - please clarify it.
- an -> and
- recomended -> recommended
- Run Msys2 shell (press Win-key once and type msys)
On my system you need to type msys2
to open the msys shell, and msys
command doesn't work.
Do not forget install VisualC++ 2015 runtime if you don't have it installed. It's used by gpu-setup.dll https://www.microsoft.com/en-us/download/details.aspx?id=52685
Ok, so my system had 3 c++ redists: 2008, and 2015-2019 (x64) and 2015-2019 (x86) so VC++ runtime fails to install over these (one has to dig into install logs to find out why in typical ms UX). Are we sure want to ask users to install this ancient runtime? Won't the 2015-2019 runtime work? Ideally we can ask users to install the latest VC++ runtime and it will work.

Really, user must have any VC140 compatible runtime. By default, windows10 does not have it. So, Yes, VC2019 will work well.
I'm not sure why searching in menu does not work with just typing msys, however, yes, msys2 must work well too.
so we need to recommend the most recent vc++ runtime that ms makes available that will work.
I will check it on clean system with VC2019 runtime today, to be sure.
