Build qtwebengine for embedded linux
-
Hi, I'm trying to build Qt 5.8.1 from source. I downloaded the source code and I run configure using this command :
./configure -release -opensource -confirm-license -device linux-s500-g++ -sysroot /mnt/lemaker/ -device-option CROSS_COMPILE=/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -prefix /opt/qt5-arm -nomake examples -nomake testsAfter that it shows me the list of configuration and asked me to run make then make install
When I run make I get this problem:code_textmake[1]: Entering directory '/qt5/qtwebengine' /qt5/qtbase/bin/qmake -o Makefile qtwebengine.pro Running configure tests Checking for alsa... yes Checking for khr... yes Checking for libvpx... no Checking for snappy... yes Checking for srtp... no Project MESSAGE: PKG_CONFIG_LIBDIR automatically set to /mnt/lemaker//usr/lib/pkgconfig:/mnt/lemaker//usr/share/pkgconfig Project MESSAGE: PKG_CONFIG_SYSROOT_DIR automatically set to /mnt/lemaker/ System zlib or minizip not found.

Why Qtwebengine won't be built and how to build it.

Check the config.log file to see what is missing.
-
hey @jsulm thank you for your quick reply. I checked the config.log file and found these errors:
```make[2]: Entering directory '/qt5/qtwebengine/tools/qmake/config.tests/libvpx' > /gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -c -pipe --sysroot=/mnt/lemaker/ -O2 -Wall -W -fPIC -I. -I/qt5/qtbase/mkspecs/devices/linux-s500-g++ -o libvpx.o libvpx.cpp > libvpx.cpp:29:10: fatal error: vpx/svc_context.h: No such file or directory > #include <vpx/svc_context.h> > ^~~~~~~~~~~~~~~~~~~ > compilation terminated. > Makefile:901: recipe for target 'libvpx.o' failed > make[2]: *** [libvpx.o] Error 1 make[2]: Leaving directory '/qt5/qtwebengine/tools/qmake/config.tests/libvpx' test libvpx FAILED And also this: ```make[2]: Entering directory '/qt5/qtwebengine/tools/qmake/config.tests/srtp' > /gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -c -pipe --sysroot=/mnt/lemaker/ -O2 -Wall -W -fPIC -I. -I/qt5/qtbase/mkspecs/devices/linux-s500-g++ -o srtp.o srtp.cpp > srtp.cpp:29:10: fatal error: srtp/srtp.h: No such file or directory > #include <srtp/srtp.h> > ^~~~~~~~~~~~~ > compilation terminated. > Makefile:901: recipe for target 'srtp.o' failed > make[2]: *** [srtp.o] Error 1 > make[2]: Leaving directory '/qt5/qtwebengine/tools/qmake/config.tests/srtp' test srtp FAILED

@Iheb You need to install libvpx and libvpx-dev I guess for your target device
-
@jsulm yes I think that is the solution. However after installing libvpx and the dev package I get the same error: svc_context.h: No such file or directory I took a look in /usr/lib and didn't find the file. After a little search I found that the newest version of libvpx-dev doesn't have svc_context.h. I'll post the solution when I find it. Thanks
-
@Iheb Did you install it in your sysroot (or synced sysroot after installation)?
-
@jsulm I've installed it in my target device (LeMaker Guitar) and I'm using sshfs to get the board's rootfs on my desktop so I think it's synced.

After that it shows me the list of configuration
please post this configuration summary output

@jsulm I managed to add the svc_context.h file in vpx and after running make I get this output:

@Iheb Please run configure from a clean state without artefacts from previous runs.
