[Tutorial] Recompiling KeeperFX - MinGW, MSYS and Coreutils

[eddebaby]

Which branch/version are you trying to build? Because to me it does not look like a problem with your build environment, but one with the code instead.

The error is from https://github.com/Loobinex/keeperfx-unofficial/ master branch

Well either #include <assert.h> is missing or your compiler is too old.

It looks like assert.h is in globals.h.

It is presumably on my end.

I am using mingw32-gcc-g++ 6.3.0-1 (I have just set up the tool chain today from this tutorial and the text file at https://github.com/dkfans/keeperfx-s...structions.txt)

What would you suggest I use for building the latest version?

Trass3r advised a while back to use WSL instead, and indeed that was a lot easier to get working. Follow these instructions for that:

Open Powershell as Administrator and type: "Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux". Restart.
Click here: https://www.microsoft.com/store/apps/9N9TNGVNDL3Q to install Ubuntu 18.04 from windows store.

Type: "sudo apt update && sudo apt upgrade" and confirm

sudo apt install make
sudo apt install unzip
sudo apt install gcc
sudo apt install g++
sudo apt-get install gcc-mingw-w64-i686
sudo apt-get install g++-mingw-w64-i686

Although there's probably something you can do to get your version to work, but I'm no expert.

[Trass3r]

Though now it's 20.04: https://www.microsoft.com/en-us/p/ubuntu/9nblggh4msv6

Unfortunately, I am on Windows 7 so I can't use WSL.

I tried mingw32-gcc-g++ ver 9.2.0-2, but no luck. mingw32-base and msys-base are ancient (ver 2013072200).

I am trying MSYS2 to see if I can get further.

[Trass3r]

Maybe the header is too old then and doesn't contain the macro: https://en.cppreference.com/w/c/language/_Static_assert
Btw I think the Windows 10 Upgrade is still possible.

[YourMaster]

I think there's just one static_assert in the entire code. So perhaps simply removing line 72 of thing_creature.h is enough to fix all your issues.

Thanks Trass3r, but I want to stay on Windows 7, it is unfortunate WSL doesn't work on it. I should upgrade soon, but not today!

I am trying MSYS2 to see if I can get further.

I can now compile with MYS2 and mingw32, thanks to Real_Gecko (https://github.com/Loobinex/keeperfx...icial/pull/168) and some googling for setting up MSYS2. Quick tutorial below.

The compiled exe seems to have broken nocd music though (installing mingw-w64-i686-libogg didn't make a difference, and no build errors either way).

That did allow the build to complete (png2ico needs libstdc++-6.dll in the root dir of the project though...).

I haven't found another way around the issue yet.






Guide for MinGW and MSYS
=================

Download MinGW Installation Manager: mingw-get-setup.exe
Latest for me is: Version 0.6.3 (Beta)

Run it and install these:
mingw32-base (latest for me is 2013072200)
mingw32-gcc-g++ (latest for me is 9.2.0-2)
msys-base (latest for me is 2013072200)

Add "C:\MinGW\bin;C:\MinGW\msys\1.0\bin" to "Path" Windows Environmental Variable (need to restart to get effect), this allows you to run programs without entering the path each time

Run sh (type sh in Windows command line)

from sh, install core-utils and unzip

mingw-get update
mingw-get upgrade (does nothing for me, all up to date)
mingw-get install msys-coreutils
mingw-get install msys-unzip

you also need curl, easy method (haven't got a hard one working yet! - build through source inmake clean sh)

download curl-7.xx.x from https://curl.haxx.se/windows/ (latest for me is curl-7.71.1 64-bit)

copy the contents of bin folder to C:/MinGW/bin

png2ico needs libstdc++-6.dll in the root dir of the project (Copy from C:/mingw)



change to root dir of the KeeperFX project (the one with Makefile in it) and build source:


make clean (use to start fresh - empty tools, objects and sdl folder for full clean) [need to run if have changed constants - and prob more]
make standard (build normal exe and dll)



Guide for MSYS2 with MinGW32
===================

Download MSYS2 installer from https://www.msys2.org/
Install and the run through instructions on above page (about using pacman)

in the "MSYS2" window

pacman -S mingw-w64-i686-gcc
pacman -S mingw-w64-i686-make
pacman -S unzip
pacman -S tar


in the "MSYS2 MinGW 32-Bit" window

change to root dir of the KeeperFX project (the one with Makefile in it) and build source:

make-mingw32 clean (use to start fresh - empty tools, objects and sdl folder for full clean) [need to run if have changed constants - and prob more]
make-mingw32 standard (build normal exe and dll)

[AdamP]

A serious issue regarding MSYS2 has come to light: it appears to corrupt your save game files.

https://github.com/dkfans/keeperfx/issues/1108

The corruption is not immediately apparent, which is probably why this went undetected until now. But until this is fixed, I suggest you use something else to build KeeperFX, such as Ubuntu/WSL.

[YourMaster]

Yeah, as you just joined us, most people build with WSL now. It's easy to setup, and works well.

• Open Powershell as Administrator and type: "Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux".
• Restart your PC
• Install the latest version of Ubuntu from the windows store. Time of writing: https://www.microsoft.com/en-gb/p/ub...s/9n6svws3rx71
• In powershell type "sudo apt update && sudo apt upgrade" and confirm.
• Do the following commands:
  - sudo apt install make
  - sudo apt install unzip
  - sudo apt install gcc
  - sudo apt install g++
  - sudo apt-get install gcc-mingw-w64-i686
  - sudo apt-get install g++-mingw-w64-i686

Now you're done and can make. Change the directory to where you have your keeperfx source, e.g:

 cd "/mnt/d/source/keeperfx"

Type 'Make standard' to build the game.

[Trass3r]

In the future installation will be even simpler:
https://docs.microsoft.com/en-us/win...ndows-insiders

And you can put it all on one line: sudo apt install -y make unzip g++ g++-mingw-w64-i686
