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
supplement: cmake -DVTK_QT_VERSION:STRING=5 -DQT_QMAKE_EXECUTABLE:PATH=/usr/lib/qt5/bin/qmake -DVTK_Group_Qt:BOOL=ON -DBUILD_SHARED_LIBS:BOOL=ON …
is ok.
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:
