How to solve the problem of not displaying the map?

The native code appears to be missing. Did you build it by following the Developer Setup instructions?
Switch to the window platform for packaging, packaging interface
Right, because we ship binaries for Windows, so you don’t need to build them manually like you do for Linux.
How does Linux need to build them manually?
Linux is not currently a supported platform for Cesium for Unity.
It’s possible to run Cesium for Unity on Linux (others have done it), but it is not simple. It doesn’t work out of the box, and there are no step-by-step instructions available. The developer setup instructions basically explain how it’s done, but they’re written for Windows. They need to be adjusted for Linux. This is especially true if you’re trying to build for Linux from Windows . That should also be possible, but I’m not aware of anyone ever having done it.
So if you want to take this on, you’ll have to work through the process carefully, understanding what you’re doing along the way. Some knowledge of C++ and CMake will be necessary. I can probably help when you run into problems, but can’t guide you through it step-by-step.
If that sounds too difficult, I’m afraid you’ll just have to wait until we add official Linux support.
What if building Linux from Linux? Would it be much easier?
Yes, it will probably be easier. We know of people that have done that successfully, at least.
building Linux from Linux，When are you planning to launch this feature?
We have no definite timeline for it right now.

The linux version compiles successfully
Hello, I need to release the Linux version. Can you add a WeChat account for a detailed chat? My WeChat account: LWK18020018226

hi, I really need to run cesium on linux, I am also usin 22.04(I got that from your desktop background). Could you please help me, guide me how you did it. My unity version is 2022.3.55f1 and I tried following the cesium developer guide(for now the cesium-unity-samples project) and I get an error:

Hi @johni , welcome to the community!
Usually, this is expected when you first setup the environment. You need to execute the dotnet publish step before you open Unity, so that the Reinterop files are generated. If you don’t see them generating, force Unity to recompile your code by adding a trivial change (such as adding whitespace) to a file in the plugin. Then, close Unity and run the cmake steps in the native~ folder.
I hope that works, but if not, it would help if you shared what you did step-by-step so we can better advise!

hi thank you for helping me out! I finally got the Unity Cesium working in ubuntu, except now there is a problem where 3d tiles won’t load. when I open the 01_CesiumWorld scene I do see terrain data but when I tried like the 03_CesiumSanFrancisco scene I see no 3d tiles. I even tried hosting my own 3d tiles world but it simply doesn’t show anything. I really need this to work. what can I do?
Hi @johni , glad you got it compiling!
You probably need to add a call to registerAllTileContentTypes. We’re not entirely sure why this is needed on Linux and not other platforms, but other users have found it helpful. See here:

Hi, first of all thanks for this amasing software!
I got an issue installing … cesium in unity on linux.
to my system:
`6.10.10-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 12 Sep 2024 17:21:02 +0000 x86_64 GNU/Linux`
`unityhub version 3.9.1` --> https://aur.archlinux.org/packages/unityhub
I installed the 2022.3.48f1 editor version
**### first attempt**
I created a new project (3D core).
under "services" -> "gerneral settings" -> "Package Manager" I added following:
```
Cesium
https://unity.pkg.cesium.com
com.cesium.unity
```
then I installed the cesium plugin in version 1.13.0
The consol log give me some errors:
```
Library/PackageCache/com.cesium.unity@1.13.0/Runtime/Cesium3DTile.cs(2,7): error CS0246: The type or namespace name 'Reinterop' could not be found (are you missing a using directive or an assembly reference?)
```
seems that Reinterop for dotnet is not coming with that repo plugin.
**### second attempt**
I followd the instructions here: https://github.com/CesiumGS/cesium-unity/blob/main/Documentation~/developer-setup.md
installed:
`extra/dotnet-sdk 8.0.8.sdk108-1 (85.3 MiB 300.0 MiB) (Installed)`
`extra/nasm 2.16.03-1 (341.2 KiB 2.4 MiB) (Installed)`
`dotnet --version 8.0.108`
`cmake version 3.30.4`
cloned [cesium-unity-samples](https://github.com/CesiumGS/cesium-unity-samples)
then `cesium-unity` inside it.
in `cesium-unity-samples/Packages/com.cesium.unity` i called:
```sh
[<user> com.cesium.unity]$ dotnet publish Reinterop~ -o .
MSBuild version 17.8.5+b5265ef37 for .NET
Determining projects to restore...
All projects are up-to-date for restore.

Reinterop -> /home/<user>/cesium-unity-samples/Packages/com.cesium.unity/
```
got the message:
```
DllNotFoundException: CesiumForUnityNative assembly:<unknown assembly> type:<unknown type> member:(null)
NotImplementedException: The native implementation is missing so OnValidate cannot be invoked.
```
did:
```sh
cd cesium-unity-samples/Packages/com.cesium.unity/native~
cmake -B build -S . -DCMAKE_BUILD_TYPE=Debug
```
run into following error:
```sh

```
now in unity i added the `cesium-unity-samples` project but with 2022.3.48f1 editor version (the 2021 one seems not work on arch anymore). logedin into cesium ion. Then added a `Blank 3D Tiles Tileset` on the gameobject `Cesium3DTileset` I switch to url and use my maps api url `https://tile.googleapis.com/v1/3dtiles/root.json?key=<my key>`
then I get following error:
```

i change the error message parameter to tileUrl wich gave me the uri provided by the maps google api
```

```
this is a valid glb compressed Json file wich I checked with https://github.khronos.org/glTF-Validator/
the google maps API sayes somethng from:
```json
"extensionsUsed": [
"3DTILES_content_gltf"
],
"extensionsRequired": [
"3DTILES_content_gltf"
]
}
```
which I didnt investigated further.
It seems that the cesium plugin have an Issue decompressin glb files.
Does you have any idea how i can fix it?
