System hangs when building QTWebEnginem

hankwang — Wed, 18 Sep 2024 06:58:01 GMT

Hey,

We want to build 6.6.23 and include QT6.7. We have added qtwebenigne to the BSP and masked the meta-chromium recipe.

When the system bitbake qtwebenigne, the system will hang. But my system has 32G RAM.

Bitbake thread set 4.

How to set up an environment for compiling qtwebengine?

I monitor memory usage. 32G memory becomes empty. Do you have any idea? We can reduce the memory usage or how we need to increase the memory size.

Are you using Ubuntu? How many cpu core in your system?

Yes, I use Ubuntu 20.04. The Core has 16.

Your host system is good enough to build the BSP.

In the conf/local.conf, please try to add below:

BB_NUMBER_THREADS="8"

PARALLEL_MAKE = "-j 8"

I set threads to 8.But I still can't bitbake qtwebenigine.

bitbake's do_compile progress is still stay at 0%.

Could you show me the steps so I can try it on my side?

Is there any error message? where is it stop?

The step is very simple.

1. Download BSP 6.6.23 BSP from NXP.

2. DISTRO=fsl-imx-xwayland MACHINE=imx8mm-lpddr4-evk source imx-setup-release.sh -b
build-xwayland

3. Modify the local.conf (set thread to

4. Add IMAGE_INSTALL:append = " packagegroup-qt6-webengine" in local.conf

5. Mask #BBLAYERS += "${BSPDIR}/sources/meta-browser/meta-chromium" in bblayer.conf

6.bitbake imx-image-full

Regarding step 3: Added the following information, set thread 8.

BB_NUMBER_THREADS="8"

PARALLEL_MAKE = "-j 8"

I solved this problem. SWAP can be modified from the default 2G to 8G.
