Integrate Filament source into Game Engine. #7961

Hi, what are you having problems with? I use C++ and in my case I include FIlament source as part of my CMake project. Here's roughly how a CMakLists.txt that adds Filament could look like: cmake_minimum_required(VERSION 3.19)
project(MyEngine)
add_subdirectory(ThirdParty/Filament) # Path to Filament source directory.
set(CMAKE_CXX_STANDARD 17)
add_library(MyEngine SHARED YOUR_SOURCE_FILES)
target_link_libraries(MyEngine filagui gltfio gltfio_core) |

I can barely recall all the steps I took before I reset my project, but I'll give it a try.
Unfortunately, I could not succeed. No matter how many libraries I linked, I always encountered some unresolved externals or mismatch errors. I regret not keeping the logs. This is my first attempt at setting up a project using Premake while integrating another project that uses CMake. I would greatly appreciate any assistance. |

Here's a Premake script that successfully compiled HelloTriangle sample for me. Trying it out using sample code is difficult, because Filament releases do not contain all necessary headers and libraries - samples use an internal helper FilamentApp class to avoid copy-pasting a lot of initialization code. In my case I have a I use macOS so I also had to include Apple frameworks, I guess there's probably some (For my projects I would still use CMake, though, since everyone already uses it so integrating other projects and libraries is just easier.) -- premake5.lua

Is this Windows? If you just want to test if Filament works right, then I think you can remove the entire Otherwise, you would have to re-implement |

Thank you. I figured it out soon after. After I fixed that I was greeted with a pleasant surprise of 1486 new errors . Build Log - 1486 Errors

Hello.
I am developing a Game Engine, and trying to integrate filament by building it from source.
I have been trying for a couple of days and I haven't seen any success.
Is there a repository or step-by-step manual I could follow ?
Can I simply use the prebuilt libraries, and be able to peek through its source ?
