[Question] Compile ITK with gcc 9

[tarnh]

Dear ITK developers,

I currently need a OTB 6.2 superbuild. My distro ArchLinux has already switched over to gcc 9. Downgrading first seemed easy to me, but all packages in the main repos are now compiled to a newer version of libstdc++.

So I've tried to build https://github.com/InsightSoftwareConsortium/ITK/tree/release-4.13 with gcc-9, which currently fails due to "deprecated copy" warnings.

I assume that you are working on that.

How I can I patch the superbuild to compile with -Wno-deprecated-copy to fix my compilation problem now?

This seems to be a duplicate of #1302

@tarnh it would be worth the effort upgrading to ITK 5 in the meantime.

Of course I'm using ITK 5 on my main system.
https://github.com/CNES/WASP is the culprit which pushes me to use the obsolete OTB 6.2.

@tarnh Are you compiling with -Werror? I am able to compile ITK with gcc9, despite those warnings.

I'm building with an opaque "SuperBuild" script, so probably yes.

BTW: Do you have any experience in compiling HDF4? If not, this issue may be closed.
