how to edit files that are not sources?

[roipoussiere]

I'm trying to build Open Cascade and I'm facing the error missing file xlocale.h. After some search I found that a solution was to create a symlink: ln -s /usr/include/locale.h /usr/include/xlocale.h

But how to do this from the flatpak context?

I tried this:

  - name: occt
    sources:
      - type: archive
        url: https://github.com/tpaviot/oce/releases/download/official-upstream-packages/opencascade-7.2.0.tgz
        md5: 5fcdd7a9bcb797ced2e4c00f59b3f5aa
      - type: shell
        commands:
          - ln -s /usr/include/locale.h /usr/include/xlocale.h
    buildsystem: cmake
    config-opts:
      - -DOCE_INSTALL_PREFIX:PATH=/app

But it seems (obviously) that sources.commands is not supposed to edit non-sources files:

Building module occt in /home/nath/divers/flat_cadquery/.flatpak-builder/build/occt-1
========================================================================
ln: failed to create symbolic link '/usr/include/xlocale.h': Read-only file system
Error: module occt: Child process exited with code 1

What should I do?

Symlink it into /app/include, or better yet, create a patch for Open Cascade that changes the include path.

Symlink it into /app/include

this works, thanks!

or better yet, create a patch for OpenCascade that changes the include path.

I don't really know how to do this but I reported it here with the solution.
