You can also find instructions here in README.release.md

Compiling

One time setup

Cloning the repo

Disable automatic CRLF handling:
Locally

git config --local core.autocrlf false

Or globally/system wide

git config --system core.autocrlf false
git config --global core.autocrlf false

Clone the repo and its submodules recursively

git clone --recurse-submodules -j8 https://github.com/otavepto/gbe_fork.git

The switch -j8 is optional, it allows Git to fetch up to 8 submodules

It is adviseable to always checkout submodules every now and then, to make sure they're up to date

git submodule update --recursive --remote

For Windows:

You need Windows 10 or 8.1 + WDK
Using Visual Studio, install Visual Studio 2022 Community: https://visualstudio.microsoft.com/vs/community/
- Select the Workload Desktop development with C++
- In the Individual componenets scroll to the buttom and select the latest version of Windows XX SDK (XX.X...)
  For example Windows 11 SDK (10.0.22621.0)
Using MSYS2 (very limited support): https://www.msys2.org/
- To build 64-bit binaries use either the environment UCRT64 or MINGW64 then install the GCC toolchain
  UCRT64
```
pacman -S mingw-w64-ucrt-x86_64-gcc
```
  MINGW64
```
pacman -S mingw-w64-i686-gcc
```
- To build 32-bit binaries use the environment MINGW32 then install the GCC toolchain
```
pacman -S mingw-w64-i686-gcc
```
Python 3.10 or above: https://www.python.org/downloads/windows/
After installation, make sure it works
```
python --version
```
(Optional) Install a GUI for Git like GitHub Desktop, or Sourcetree

For Linux:

Ubuntu 22.04 LTS: https://ubuntu.com/download/desktop

Ubuntu required packages:

sudo apt update -y
sudo apt install -y coreutils # echo, printf, etc...
sudo apt install -y build-essential
sudo apt install -y gcc-multilib # needed for 32-bit builds
sudo apt install -y g++-multilib
sudo apt install -y libglx-dev # needed for overlay build (header files   such as GL/glx.h)
sudo apt install -y libgl-dev # needed for overlay build (header files   such as GL/gl.h)

(Optional) Additional packages

sudo apt install -y clang # clang compiler
sudo apt install -y binutils # contains the tool 'readelf' mainly, and   other usefull binary stuff

Python 3.10 or above

sudo add-apt-repository ppa:deadsnakes/ppa -y
sudo apt update -y
sudo apt install python3.10 -y

# make sure it works
python3.10 --version

Building dependencies

These are third party libraries needed to build the emu later, they are linked with the emu during its build process.
You don't need to build these dependencies every time, they rarely get updated.
The only times you'll need to rebuild them is either when their separete build folder was accedentally deleted, or when the dependencies were updated.

On Windows:

Open CMD in the repo folder, then run the following

To build using Visual Studio

set "CMAKE_GENERATOR=Visual Studio 17 2022"
third-party\common\win\premake\premake5.exe --file=premake5-deps.lua --64-build --32-build --all-ext --all-build --verbose --os=windows vs2022

To build using MSYS2
(Optional) In both cases below, you can use Clang compiler instead of GCC by running these 2 commands in the same terminal instance

export CC="clang"
export CXX="clang++"

To build 64-bit binaries (UCRT64 or MINGW64)

export CMAKE_GENERATOR="MSYS Makefiles"
./third-party/common/win/premake/premake5.exe --file=premake5-deps.lua --64-build --all-ext --all-build --verbose   --os=windows gmake2

To build 32-bit binaries (MINGW32)

export CMAKE_GENERATOR="MSYS Makefiles"
./third-party/common/win/premake/premake5.exe --file=premake5-deps.lua --32-build --all-ext --all-build --verbose   --os=windows gmake2

This will:

Extract all third party dependencies from the folder third-party into the folder build\deps\win
Build all dependencies

On Linux:

Open a terminal in the repo folder (Optional) You can use Clang compiler instead of GCC by running these 2 commands in the current terminal instance

export CC="clang"
export CXX="clang++"

Then run the following

export CMAKE_GENERATOR="Unix Makefiles"
./third-party/common/linux/premake/premake5 --file=premake5-deps.lua --64-build --32-build --all-ext --all-build --verbose --os=linux gmake2

This will:

Extract all third party dependencies from the folder third-party into the folder build/deps/linux
Build all dependencies (32-bit and 64-bit)

Building the emu

On Windows:

Open CMD in the repo folder, then run the following

For MSYS2

./third-party/common/win/premake/premake5.exe --file=premake5.lua --genproto --os=windows gmake2

cd ./build/project/gmake2/win

(Optional) You can use Clang compiler instead of GCC by running these 2 commands in the current terminal instance

export CC="clang"
export CXX="clang++"

64-bit build (UCRT64 or MINGW64)
```
make config=release_x64 -j 8 all
```
32-bit build (MINGW32)
```
make config=release_x32 -j 8 all
```

To see all possible build targets

make help

For Visual Studio 2022
```
third-party\common\win\premake\premake5.exe --file=premake5.lua --genproto --os=windows vs2022
```
You can then go to the folder build\project\vs2022\win and open the produced .sln file in Visual Studio.
Or, if you prefer to do it from command line, open the Developer Command Prompt for VS 2022 inside the above folder, then:
```
msbuild /nologo /v:n /p:Configuration=release,Platform=Win32 gbe.sln

msbuild /nologo /v:n /p:Configuration=release,Platform=x64 gbe.sln
```

This will build a release version of the emu in the folder build\win\<toolchain>\release
An example script build_win_premake.bat is available, check it out

On Linux:

Open a terminal in the repo folder, then run the following

./third-party/common/linux/premake/premake5 --file=premake5.lua --genproto --os=linux gmake2
cd ./build/project/gmake2/linux

(Optional) You can use Clang compiler instead of GCC by running these 2 commands in the current terminal instance

export CC="clang"
export CXX="clang++"

Then run the following

make config=release_x32 -j 8 all
make config=release_x64 -j 8 all

To see all possible build targets

make help

This will build a release version of the emu in the folder build/linux/<toolchain>/release
An example script build_linux_premake.sh is available, check it out

Building the tool `generate_emu_config`

Navigate to the folder tools/generate_emu_config/ then

On Windows:

Open CMD then:

Create python virtual environemnt and install the required packages/dependencies
```
recreate_venv_win.bat
```
Build the tool using pyinstaller
```
rebuild_win.bat
```

This will build the tool inside bin\win

On Linux:

Open bash terminal then:

Create python virtual environemnt and install the required packages/dependencies
```
sudo ./recreate_venv_linux.sh
```
You might need to edit this script to use a different python version.
Find this line and change it:
```
python_package="python3.10"
```
Build the tool using pyinstaller
```
./rebuild_linux.sh
```

This will build the tool inside bin/linux

Using Github CI as a builder

This is really slow and mainly intended for the CI Workflow scripts, but you can use it as another outlet if you can't build locally.
You have to fork the repo first.

Initial setup

In your fork, open the Settings tab from the top, then:

From the left side panel select Actions -> General
In the section Actions permissions select Allow all actions and reusable workflows
Scroll down, and in the section Workflow permissions select Read and write permissions
(Optional) In the section Artifact and log retention, you can specify the amount of days to keep the build artifacts/archives.
It is recommended to set a reasonable number like 3-4 days, otherwise you may consume your packages storage if you use Github as a builder frequently, more details here: https://docs.github.com/en/get-started/learning-about-github/githubs-plans

Manual trigger

Go to the Actions tab in your fork
Select the emu dependencies Workflow (ex: Emu third-party dependencies (Windows) ) and run it on the main branch (ex: dev).
Dependencies not created on the main branch won't be recognized by other branches or subsequent runs
Select one of the Workflow scripts from the left side panel, for example Build all emu variants (Windows)
On the top-right, select Run workflow -> select the desired branch (for example dev) -> press the button Run workflow
When it's done, many packages (called build artifacts) will be created for that workflow.
Make sure to select the workflow again to view its history, then select the last run at the very top to view its artifacts

Important note:

When you build the dependencies workflows, they will be cached to decrease the build times of the next triggers and avoid unnecessary/wasteful build process.
This will cause a problem if at any time the third-party dependencies were updated, in that case you need to manually delete the cache, in your fork:

Go to the Actions tab at the top
Select Caches from the left side panel
Delete the corresponding cache

(Optional) Packaging

This step is intended for Github CI/Workflow, but you can create a package locally.

On Windows:

Open CMD in the repos's directory, then run this script

package_win.bat <build_folder>

build_folder is any folder inside build\win, for example: vs2022\release
The above example will create a .7z archive inside build\package\win\

On Linux:

Open bash terminal in the repos's directory, then run this script

package_linux.sh <build_folder>

build_folder is any folder inside build/linux, for example: gmake2/release
The above example will create a compressed .tar archive inside build/package/linux/
