[Buildroot] QT5 camera error: Unknown module(s) in QT: multimedia multimediawidgets

[Buildroot] QT5 camera error: Unknown module(s) in QT: multimedia multimediawidgets

[Julia Ding]

I run qt camera demo, and it show this error

:-1: error: Unknown module(s) in QT: multimedia multimediawidgets

So I add qt5multimedia. (I'm using 'imx6-sabresd_qt5_defconfig' +
qt5multimedia.)
Then, build. Show this error:

Makefile:179: recipe for target 'sub-plugins-make_first' failed
make[3]: *** [sub-plugins-make_first] Error 2
Makefile:46: recipe for target 'sub-src-make_first' failed
make[2]: *** [sub-src-make_first] Error 2

How to fix this? Thanks.

Thanks for your report. Could you:

 (1) Make sure this error happens when you do a rebuild from scratch
     ("make clean all")

 (2) Post the .config, and the last ~200 lines of build output. The
     part of the error log you have copy/pasted is not sufficient to
     understand the issue.

Thanks!

Thomas

Hello Thomas:

Thanks for your answer.
After "make clean all" and "make" again, it show another error 
/usr/include/EGL/egl.h:39:0, 
                 from qsgvideonode_egl.h:48, 
                 from qsgvideonode_egl.cpp:40: 
/home/gportay/src/buildroot/output-qt5.10/host/x86_64-buildroot-linux-gnu/sysroot/usr/include/EGL/eglplatform.h:118:22: 
fatal error: X11/Xlib.h: No such file or directory 
#include <X11/Xlib.h> 
                     ^ 
I find a patch "qt5base: fix build issue with mesa3d w/out xcb" to fix.
?https://patchwork.ozlabs.org/cover/880120/?
The previous error message did not appear. May be something changed before
in menuconfig, I didn't record them.
