NOTE: The main difference between this package and itk4 is that itk4 conflicts with insight-toolkit (i.e. the latest ITK version), while this package can be installed in parallel and allows having both ITK4 and ITK5 available on the same system.

I was having the same build errors as @skualos and some other GCC 16 compatibility errors, the following prepare() function fixes them:

prepare() {
    cd "${srcdir}/InsightToolkit-${pkgver}" || return

Getting build error related to cmake version:

==> Starting build()...
CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

==> ERROR: A failure occurred in build().

 -> error making: insight-toolkit4-exit status 4
 -> Failed to install the following packages. Manual intervention is required:
insight-toolkit4 - exit status 4

Adding -DCMAKE_POLICY_VERSION_MINIMUM=3.5 as suggested goes a bit further in the build but still fails:

Thanks for updating!

@FabioLolix: Removed, thanks!

Hello, would you like to remove provides=("insight-toolkit=${pkgver}")?

Since this can be installed alongside insight-toolkit and is not a drop-in replacement for it, using provide insight-toolkit seems that this an equivalent while is not true since pkgbuild need to be intentionally configured to use this version; like your itk-snap pkgbuild do

have not hdf5-cpp-fortran。
