hi,

Another Ubuntu 20(aarch64),GNU Make 4.2.(aarch64-unknown-linux-gnu), gcc (Ubuntu 9.4.0-19ubuntu1) 9.4.0 is OK.
But this show problem now.
How to do it, can i get some hints or VTK-7.1.1 is not surported on Ubuntu 22.04.1 LTS
Thanks a lot.

I’m surprised VTK 7 got that far myself. It’s certainly not supported by VTK developers anymore. Is there a reason you can’t use VTK 9?

You know, in order to maintain the old version program, reducing the work load. VTK 8.2 is same problem.

I’m in the same boat, I’ve got a few apps comprised of tens of thousands of lines of code that are based on VTK 7. For these legacy apps that only require VTK’s old functionalities, upgrading to a newer VTK requires a lot of work for no benefit, in fact even recompiling these apps is a rare occurrence. Rebuilds and upgrades of legacy apps occur only when necessary, because generally I’ve got better things to spend my time on.
For legacy code, I just keep old systems/toolchains around. For Linux I have an older ubuntu installed in a separate root partition, and I chroot the older root before running “make”. Docker can be used similarly. Directories can be shared between the docker/chroot and the main system. Executables compiled with old toolchains generally run fine on newer systems, particularly for VTK since nearly all of its library dependencies are built-in.

The problem originates in regex for getting the compiler version from the output of `gcc --version`.
In case the major compiler version has more than one digit (\>= 10) the macro `_vtk_test_compiler_hidden_visibility`
which is defined in:
`VTK-7.1.1/CMake/VTKGenerateExportHeader.cmake`
does not work as expected.
You can give the following patch for VTK 7.1.1 a try:
```auto
diff -ruN VTK-7.1.1.orig/CMake/VTKGenerateExportHeader.cmake VTK-7.1.1/CMake/VTKGenerateExportHeader.cmake

Thank you @mrbachmann I had the same linkage problem and this solved the issue.
Using gcc 11.5 on rocky 9 there are a few other compilation issues but nothing unfixable.
Thanks again
