Sceneloader cannot load 3D models under Linux

[rensiyuan]

I use sceneloader in Windows to successfully load .obj and .mtl files, but I can't display the model when running under Linux, and I get the following error:

Qt3D.Renderer.SceneLoaders: Qt3DCore::QEntity* Qt3DRender::Render::LoadSceneJob::tryLoadScene(Qt3DRender::Render::Scene*, Qt3DRender::QSceneLoader::Status&, const QStri)

I run the paogram under the nxp development board， and my qt version is 5.10.1.
Anybody can help me? Thanks in advance :)

Hi and welcome to devnet,

Something is not clear, are you developing directly on the NXP board ?
Cross-compiling ?
If it's a deployed application, did you also deploy the needed plugins ?

[rensiyuan]

hello,
I'm developing directly on the NXP board and it's Cross-compiling.
These figures show the plugins deployed for Qt.


And these are QT configuration parameters in qtbse_git.bb

Do you see any problems with this information?
Thanks a lot！

What system are you using to create these images ?
It looks like there are sceneparsers plugins missing.

[rensiyuan]

@SGaist hi, SGaist, these are the sceneparsers plugins in Qt 5.10.1 sdk:
./qt/sdknew/sysroots/aarch64-poky-linux/usr/lib/qt5/plugins/sceneparsers/libgltfsceneexport.so
./qt/sdknew/sysroots/aarch64-poky-linux/usr/lib/qt5/plugins/sceneparsers/libgltfsceneimport.so
./qt/sdknew/sysroots/aarch64-poky-linux/usr/lib/qt5/plugins/geometryloaders/libgltfgeometryloader.so

I don't found any assimp.so in sceneparsers, and I have these in sdk:

./qt/sdk/sysroots/x86_64-pokysdk-linux/usr/lib/libassimp.so.3
./qt/sdk/sysroots/x86_64-pokysdk-linux/usr/lib/libassimp.so
./qt/sdk/sysroots/x86_64-pokysdk-linux/usr/lib/libassimp.so.3.3.1
./qt/sdk/sysroots/aarch64-poky-linux/usr/lib/.debug/libassimp.so.3.3.1
./qt/sdk/sysroots/aarch64-poky-linux/usr/lib/libassimp.so.3
./qt/sdk/sysroots/aarch64-poky-linux/usr/lib/libassimp.so
./qt/sdk/sysroots/aarch64-poky-linux/usr/lib/libassimp.so.3.3.1

Does it mean that I did not generate a libassimpsceneimport.so ?

Or there are some wrongs about my qt3d Configuration？

By the way, it has another name called assimpsceneimport.dll in the Windows , and libassimpsceneimport.so in the Ubuntu.

I have no idea. Thank you for your help.

[SGaist]

You should inspect your SDK build logs to see why it failed to detect assimp when configuring Qt.
