Cesium Prerequisites

alessandro_mancini · May 22, 2023, 3:20pm

Hello,
I’m trying to build a unity project with cesium for unity 1.2.0.
If i build it in my unity editor i have no problem.
But if i build it with this docker image: unityci/editor:2021.3.25f1-windows-mono-1.1 i
have the following error.

I believe there is any dependency issue in the editor docker image, which doesn’t allow tu build
the project with cesium.

Any hint on any particular prerequisites of cesium in an ubuntu bases docker image ?

Cesium for Unity only includes binaries for Windows (Intel), macOS (both Intel and Apple), Android (Intel and ARM), and iOS. Only 64-bit platforms are supported, there is no support for any 32-bit platform.

If your Docker image isn’t one of the supported platforms, then that is the problem.

If you’re trying to build Cesium for Unity yourself from source rather than using the version that includes pre-built native code, you’ll need to follow the Developer Setup instructions.

alessandro_mancini · May 24, 2023, 6:52am

I @Kevin_Ring, thank you for your reply.
I’m using Unity Package Manager to download Cesium for Unity.
I have the manifest.json with the following entry:

“com.cesium.unity”: “1.2.0”,

The docker image i’m using is unityci/editor:2021.3.25f1-windows-mono-1.1 which is based on Ubuntu, and the supported architecture is linux/amd64. So i think it should work, right ?

Kevin_Ring · May 24, 2023, 7:17am

No, Linux is not a supported platform.

We’ve successfully compiled and run it on Linux, so it’s definitely possible. But we don’t include the necessary binaries out of the box yet. If you need to run on Linux, you currently need to compile the native code yourself by following the developer setup instructions, adapting them for Linux along the way:

# Overview

This is a summary of the setup and workflows for developers who want to modify the Cesium for Unity plugin. If you just want to use Cesium for Unity in your own applications, see the main [README](../README.md).

## :computer: Building Cesium for Unity

### Prerequisites

* CMake v3.15 or later (the latest version is recommended)
* [.NET SDK v6.0 or later](https://dotnet.microsoft.com/en-us/download/dotnet/6.0)
* If you're using Visual Studio, you need Visual Studio 2022.
* Unity 2021.3+ (the latest version of the Unity 2021.3 LTS release is recommended)
* On Windows, support for long file paths must be enabled, or you are likely to see build errors. See [Maximum Path Length Limitation](https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry#enable-long-paths-in-windows-10-version-1607-and-later).
* For best JPEG-decoding performance, you must have [nasm](https://www.nasm.us/) installed so that CMake can find it. Everything will work fine without it, just slower.

The built Cesium for Unity Assembly will run on much older versions of .NET, including the version of Mono included in Unity. However, these very recent versions are required for the C#<->C++ interop code generator (Reinterop).

To make sure things are set up correctly, open a command-prompt (PowerShell is a good choice on Windows) and run:

* `dotnet --version` and verify that it reports 6.0 or later

Ok, i undestrand.
I’m trying to build from source.
If i have a build script which runs on a pipeline, once i have cesium binary, where i have to put inside my unity project?

Thank you in advance for your support.

alessandro_mancini · May 31, 2023, 2:58pm

I’m getting this error, when building Cesium for Unity on an ubuntu based docker image:

cmake -B build -S . -DCMAKE_BUILD_TYPE=RelWithDebInfo
...
...
cmake --build build -j14 --target install --config RelWithDebInfo

/com.cesium.unity/native~/extern/cesium-native/CesiumGltf/src/FeatureTexturePropertyView.cpp:72:11: error: conversion to ‘std::__cxx11::basic_string::size_type {aka long unsigned int}’ from ‘const int32_t {aka const int}’ may change the sign of the result

Kevin_Ring · June 1, 2023, 1:57am

What compiler are you using? Looking at line 72, that error doesn’t make much sense. And I just confirmed I can compile it successfully under Ubuntu on WSL2 with GCC 9.4.0.
