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: [email protected]
Reporter: [email protected]
CC: [email protected]
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/linux/BUILD.gn:24:3: whence it was called.

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

Known problem, see [1], [2], and [3] for workaround/hack for solving it (and
[4] for more discussion of the problem)...

--- Comment #2 from Wojciech Ziniewicz <[email protected]> --- Hello Peter - thank you for the response. I think it still leads me to nowwhere but your memory of the issues is impressive.
[1] describes a problem that looks similar but it refers to problem with stdlib.h while I'm having a problem with pkg-config / freetype
[2] the problem from this one was already patched and I confirmed I'm using a patched version with QMAKE_ISYSTEM set to blank string
[3] this problem is _exactly_ what I'm seeing but still - the fix is in the main branch and I also explicitly added the BR2_PACKAGE_QT5BASE_FONTCONFIG in addition to the fact that qt5webengine requires is as a dependency itself now
[4] this is exeactly what I've done (actually my change is unnecessary as these dependencies are automatically sucked in after the changes)
So basically even after I explicitly add the deps for fontconfig, I still get the error.

--- Comment #3 from Peter Seiderer <[email protected]> --- (In reply to Wojciech Ziniewicz from comment #2)
I am pretty sure patch [3] is not in mainline ;-),
the trick is not the enabling of the target fontconfig/libjepeg but to force host-fontconfig/host-libjpeg to be available to fullfill the qt5webengine host-pkg-search for all/some libs enabled only for the target...

--- Comment #5 from Wojciech Ziniewicz <[email protected]> --- Wonderful - Peter - let me try to use that in my build system and get back with comments.
What are the chances these patches are included in the mainline?
