hello,  
i’m using ITK version 4.13.2.

i manage to compile it for Windows (using VS2017), but when i try to compile to cross compilation i get problems:  
First, I had a problem with this:

CMAKE\_CURRENT\_BINARY\_DIR

It says I have too long folder. So I set it to short in the cmake file (because it something that I don’t know where it comes from)

Then I had problems with

itk please set the following cache variables appropriately: qnanhibit\_value (advanced) qnanhibit\_value\_\_tryrun\_output (advanced)

so I found in the internet setting for that (“1” for the first and “-DTEEM\_QNANHIBIT=1” for the second)

then I got problems with this:

H5\_NO\_ALIGNMENT\_RESTRICTIONS\_RUN

H5\_NO\_ALIGNMENT\_RESTRICTIONS\_RUN\_\_TRYRUN\_OUTPUT

So I set it to “0” and “” (I found somewhere).

And now I have this problem:

ITK\_bld\_internal\_H5make\_libsettings is not recognized as an internal or external command, operable program or batch file.

anyone have any suggestion?

Thanks in advance,

---

Which platform are you trying to cross-compile to? If a platform is not normally supported, cross-compiling to it will not work either. Take a look at current version’s [dashboard](https://open.cdash.org/index.php?project=Insight) to see which platforms are tested and work.

ITK 5.0.1 or later is recommended.

HDF5 has cross-compiling challenges. However, we have patched HDF5 so its H5make\_libsettings can build easily with [`CMAKE_CROSSCOMPILING_EMULATOR`](https://cmake.org/cmake/help/v3.15/variable/CMAKE_CROSSCOMPILING_EMULATOR.html?highlight=cmake_crosscompiling_emulator), if set.

[dockcross](https://github.com/dockcross/dockcross), provides a QEMU User executable for this task. Otherwise, you may need to build and run the executable manually on the target system.

The use of _CMAKE\_CROSSCOMPILING\_EMULATOR_ also prevents the need to manually populate _tryrun_ outputs.

Have you tried the _dockcross/linux-arm64_ toolchain?
