            Bug ID: 14461
           Summary: Qt5webenegine does not build due to
                    fontconfig/freetype dependency problem
           Product: buildroot
           Version: 2021.08.2
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: wojciech.ziniewicz@gmail.com

  Target Milestone: ---

Hello,
I'm experiencing the same qt5 webengine build problem on x86 64 bit
architecture with following combinations of gcc and buildroot:
- gcc8, gcc9, gcc10
- 2021.08.2, 2021.08.3, 2021.11

It seems that qt5webengine requires freetype2.pc file which exists (parallel to
other .pc files). Both pkg config/fontconfig and freetype are normally
available.
The freetype/fontconfig pair is compiled prior to qt5webengine and it does not
really matter whether I explicitly add them to the config file or not because
they are included via FONTCONFIG dependency in qt5webengine.

-------------------------------- the error:
ERROR at //build/config/linux/pkg_config.gni:103:17: Script returned non-zero
exit code.
    pkgresult = exec_script(pkg_config_script, args, "value")

Perhaps you should add the directory containing `freetype2.pc'
to the PKG_CONFIG_PATH environment variable
Package 'freetype2', required by 'virtual:world', not found
Could not run pkg-config.

See //build/config/freetype/BUILD.gn:10:24: which caused the file to be
included.
