Description Mattias Ellert 2023-07-13 07:23:27 UTC
Description of problem:
Package qt6-qtwebengine fails to build from source in Fedora Rawhide.

Version-Release number of selected component (if applicable):

Steps to Reproduce:
koji build --scratch f39 qt6-qtwebengine-6.5.1-2.fc39.src.rpm

Additional info:

The build log ends with:

ModuleNotFoundError: No module named 'six.moves'

This issue can be solved by adding the following line in the %prep section of the soecfile:

sed "s;'six', ;;" -i src/3rdparty/chromium/tools/grit/grit/

However, after fixing this the build instead fails with:

/usr/bin/python3 ../../../../../src/3rdparty/chromium/mojo/public/tools/mojom/ --input-root ../../../../../src/3rdparty/chromium --input-root gen --output-root gen --mojom-file-list=__chrome_browser_ui_webui_internals_user_education_mojo_bindings__parser__builddir_build_BUILD_qtwebengine-everywhere-src-6.5.1_redhat-linux-build_src_core_target_toolchain_target__rule..rsp --check-imports gen/chrome/browser/ui/webui/internals/user_education/mojo_bindings.build_metadata --enable-feature is_posix --enable-feature is_linux --add-module-metadata webui_module_path=/chrome/browser/ui/webui/internals/user_education

    import imp
ModuleNotFoundError: No module named 'imp'

The imp module was removed from Pythin 3.12. Several files in 3rdparty/chromium use it and must be updated-

Reproducible: Always
