Ga?l, Peter,

The raspberrypi3_qt5we_defconfig in Buildroot no longer buids:

  https://gitlab.com/buildroot.org/buildroot/-/jobs/269139278

The error is:

error: stdlib.h: No such file or directory
 #include_next <stdlib.h>
               ^~~~~~~~~~
compilation terminated.

When building qt5webengine. Could you have a look and propose a patch
to address this issue ?

Thanks!

Thomas

I will have a look to it. Probably later that week.

Have you had the chance to look into this ? It failed again in the last
Gitlab CI pipeline:
https://gitlab.com/buildroot.org/buildroot/-/jobs/273673252.

Thanks,

I had a look that week end.

I observed that there is some -isystem CFLAGS in the generated ninja
files.

	-isystem../../../../../host/arm-buildroot-linux-gnueabihf/sysroot/usr/include/libpng16
	-isystem../../../../../host/arm-buildroot-linux-gnueabihf/sysroot/usr/include
	-isystem../../../../../host/arm-buildroot-linux-gnueabihf/sysroot/usr/include/freetype2

If I substitute the -isystem in -I, the file compile then but webgengine
fails to the next subproject with -isystem flags.

IIUC, qtwebengine uses qmake that uses ng to generate ninja files.

I am looking for the culprit that introduces the -isystem flags. I am
not yet familiar with ng/ninja, and I have basic knowledge of
qmake only.

Did you check https://bugreports.qt.io/browse/QTBUG-53367, which seems
related, but more for qmake-generated Makefiles.

We have https://bugs.busybox.net/show_bug.cgi?id=11776, which is in
fact reporting two different qt5webengine issues, the second being the
same as the one you are facing.
