Building on Windows
The easiest way to compile and run re3 is to first install Visual Studio 2015 or later in your machine. You need to make sure you also download the "Desktop development with C++" additional package as shown in the image below.
Visual Studio Installer: C++ Tools
You'll need git installed in your computer to pull the code. You can get it here. Then open Command Prompt and change directory (cd) to a path where you would like to store the code like C:\Windows. Don't forget to include the --recursive parameter. Otherwise additional dependencies won't be downloaded and the code will not compile.
You should also use setx to define the directory where GTA is installed in your computer. Usually it's in C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto 3. This is necessary to copy the re3 executable into GTA 3 directory after each build.
If the clone succeed then a folder called re3 will be created. You can just cd re3 or open with the File Explorer. You can click one of premake-vs<X>.cmd files to generate the VS solution files. In my case, as VS 2019 is installed, then it would be premake-vs2019.cmd.
A build folder will be created. Open it and click at re3.sln file to open the project.
You should see a window that looks like this. Let's choose win-x86-librw_d3d9-oal configuration to get started. Either press F7 key into your keyboard or go to Build > Build Solution menu entry.
Now you must copy some extra DLL files to your GTA installation directory. Copy both of vendor/mpg123/dist/Win32/libmpg123-0.dll and vendor/openal-soft/dist/Win32/OpenAL32.dll there like shown in the image below. Also note: your game directory should be as vanilla as possible. In other words, don't install any modifications (e.g. CLEO), otherwise the game may crash.
If you compile the "Debug" variant the executable will be only named re3.exe. The "Release" one will be re3-release.exe. Note that both libmpg123-0.dll and OpenAL32.dll are copied into the game folder.
The basic syntax to generate the build files using premake is: premake5 COMMAND [options...]. The command can be any of vs<X> (e.g. vs2019). The options are listed below:
-
with-librw: compile using the open source RW implementation by aap. This will require the dependency to be present atvendor/librw -
with-asan: build with address sanitizer -
with-lto: build with link time optimization -
glfwdir64: specify the path to GLFW 64-bit installation directory (where you unpacked the .zip file) -
glfwdir32: specify the path to GLFW 32-bit installation directory -
no-git-hash: disable generating the repository hash every build -
no-full-paths: don't print full paths into binary (windows only)
If you want to compile with GLFW, then you must specify --glfwdir<X>. If you unpack the zip file into the vendor folder, then this won't be necessary.
You can also run premake5 --help to view a full list of options.
