Have anyone tried to compile 3D Slicer from scratch under the aarch64 architecture?

I have a RockPro64 board from Pine64 vendor with a RK3399 chip. Linux distribution is the same as for x86\_64 machine. I’m trying to compile the Slicer debug build from source with default parameters. Compilation process for python 3.9.10 and DCMTK packages goes without problem, but VTK package compilation unable to start.

Shell output says that `PythonSlicer` file has wrong file format.

Some console output:

```auto

```

I’ve checked `PythonSlicer` binary file and the `reafelf` command says that it’s a x86\_64 binary, instread of aarch64. How can it be under the ARM architecture?

I only know of arm support for the new macs, which can be [compiled from source](https://github.com/Slicer/Slicer/issues/5944#issuecomment-1328179343).

It looks like you will need to investigate the python build arguments to get a workable python, but probably this can be made to work. Let us know how it goes.

The problem was with the CTKAPPLAUNCHER package. The binary packages is downloaded from CTK [repo](https://github.com/commontk/AppLauncher/releases/download/v0.1.31/CTKAppLauncher-0.1.31-linux-amd64.tar.gz), and it precompiled for amd64. Since there is no architecture check in [cmake](https://github.com/Slicer/Slicer/blob/main/SuperBuild/External_CTKAPPLAUNCHER.cmake) file for CTKAPPLAUNCHER and there is no build release for arm64 anyway, the simple solution was to compile AppLauncher from the source and replace binary exec file.

Compilation is in progress.

Good news: i’ve managed to compile successfully (the only problem was CTKAPPLAUNCHER).  
Bad news: first start shows that most of modules are failed to be installed.

Screen of the first start:

It looks like some sort of problem with VTK and python.

Nice progress 👍

Yes, it looks like a path problem. You can inspect the environment by launching a shell with the launcher (e.g. `./Slicer --launch bash`) and see if the `PYTHONPATH` and `LD_LIBRARY_PATH` directories correspond to your build tree. Probably you can set them manually to get things to load. Once you have that you can see how to fix the build process to set them automatically.

I was able to compile and run 3D Slicer successfully only the Release build with gcc-13.2 compiler and enabled VTK testing. First attempt with gcc-12.2 was a failure, mainly because of vtkSOADataArrayTemplate python wrapper (linker message `VTK python binding undefined symbols vtkSOADataArrayTemplate`), and only one third of VTK tests were successful.

After compiler upgrade and several failed attempts (Debug build; build without VTK tests) the compilation process was finally successful and 3D Slicer first start went without errors!

Some features will not work in any case due to limitations of Mali GPU in SoC. The MRHead test data was loaded and visualized (even simple VolumeRendering) but with a lot of VTK output because of shaders.

That topic was very useful as well.
