## :large_orange_diamond: **This is a fork** Fork of https://gitlab.com/Mr_Goldberg/goldberg_emulator ### Feel free to make a PR. --- :red_circle: **This fork is not a takeover, not a resurrection of the original project, and not a replacement.** **This is just a fork, don't take it seriously.** **You are highly encouraged to fork/clone it and do whatever you want with it.** :red_circle: --- ## **Compatibility** This fork is incompatible with the original repo, lots of things has changed and might be even broken. If something doesn't work, feel free to create a pull request with the appropriate fix, otherwise ignore this fork and use the original emu. --- ## **Credits** Thanks to everyone contributing to this project in any way possible, we try to keep the [CHANGELOG.md](./CHANGELOG.md) updated with all the changes and their authors. This project depends on many third-party libraries and tools, credits to them for their amazing work, you can find their listing here in [CREDITS.md](./CREDITS.md). --- # How to use the emu * **Always generate the interfaces file using the `generate_interfaces` tool.** * **If things don't work, try the `ColdClientLoader` setup.** You can find helper guides, scripts, and tools here: **(These guides, scripts, and tools are maintained by their authors.)** * **[GBE Fork Tools](https://github.com/Detanup01/gbe_fork_tools)** * **[Semuexec](https://gitlab.com/detiam/Semuexec)** * **[Steam Emu Utility](https://github.com/turusudiro/SteamEmuUtility)** * **[How to use Goldberg Emulator](https://rentry.co/goldberg_emulator)** * **[GSE-Generator](https://github.com/brunolee-GIT/GSE-Generator)** * **If you created a generator tool create a Feature PR** You can also find instructions here in [README.release.md](./post_build/README.release.md) --- ---
# **Compiling** ## One time setup ### **Cloning the repo** Clone the repo and its submodules **recursively** ```shell git clone --recurse-submodules -j8 https://github.com/Detanup01/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 ```shell git submodule update --init --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` **this is currently experimental and will not work due to ABI differences**: https://www.msys2.org/

steps * To build 64-bit binaries use either the [environment](https://www.msys2.org/docs/environments/) `UCRT64` or `MINGW64` then install the GCC toolchain `UCRT64` ```shell pacman -S mingw-w64-ucrt-x86_64-gcc ``` `MINGW64` ```shell pacman -S mingw-w64-i686-gcc ``` * To build 32-bit binaries use the environment `MINGW32` then install the GCC toolchain ```shell pacman -S mingw-w64-i686-gcc ```
* Python 3.10 or above: https://www.python.org/downloads/windows/ After installation, make sure it works ```batch python --version ``` * *(Optional)* Install a GUI for Git like [GitHub Desktop](https://desktop.github.com/), or [Sourcetree](https://www.sourcetreeapp.com/) ### For Linux: * Ubuntu 22.04 LTS: https://ubuntu.com/download/desktop * Ubuntu required packages: ```shell 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 ```shell 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 ```shell sudo apt update -y sudo apt install -y software-properties-common sudo add-apt-repository ppa:deadsnakes/ppa -y sudo apt update -y sudo apt install -y "python3.12" sudo apt install -y "python3.12-dev" sudo apt install -y "python3.12-venv" sudo apt install -y python3-dev # make sure it works python3.12 --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` ```batch 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` **this is currently experimental and will not work due to ABI differences**
steps *(Optional)* In both cases below, you can use `Clang` compiler instead of `GCC` by running these 2 commands in the same terminal instance ```shell export CC="clang" export CXX="clang++" ``` * To build 64-bit binaries (`UCRT64` or `MINGW64`) ```shell 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`) ```shell 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 ```shell export CC="clang" export CXX="clang++" ``` Then run the following ```shell 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 `Visual Studio 2022` ```batch 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: ```batch msbuild /nologo /v:n /p:Configuration=release,Platform=Win32 gbe.sln msbuild /nologo /v:n /p:Configuration=release,Platform=x64 gbe.sln ``` * For `MSYS2` **this is currently experimental and will not work due to ABI differences**
steps ```shell ./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 ```shell export CC="clang" export CXX="clang++" ``` * 64-bit build (`UCRT64` or `MINGW64`) ```shell make config=release_x64 -j 8 all ``` * 32-bit build (`MINGW32`) ```shell make config=release_x32 -j 8 all ``` To see all possible build targets ```shell make help ```
This will build a release version of the emu in the folder `build\win\\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 ```shell ./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 ```shell export CC="clang" export CXX="clang++" ``` Then run the following ```shell make config=release_x32 -j 8 all make config=release_x64 -j 8 all ``` To see all possible build targets ```shell make help ``` This will build a release version of the emu in the folder `build/linux//release` An example script `build_linux_premake.sh` is available, check it out --- ## **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 1. Go to the `Actions` tab in your fork 2. 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 3. Select one of the Workflow scripts from the left side panel, for example `Build all emu variants (Windows)` 3. On the top-right, select `Run workflow` -> select the desired branch (for example `dev`) -> press the button `Run workflow` 4. 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: 1. Go to the `Actions` tab at the top 2. Select `Caches` from the left side panel 3. 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 ```batch package_win.bat ``` `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 ```shell package_linux.sh ``` `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/`
