QtWebEngine will not be built. Platform unsupported

Hupe

I am cross-compiling Qt for ARM board. My source file is Qt 5.14.1 and tool chain is gcc-linaro-5.3.1.
This is my configuration :

#!/bin/bash

./configure \
        -v \
        -prefix /opt/Qt5.14 \
        -opensource \
        -confirm-license \
        -debug \
        -release \
        -shared \
        -strip \
        -qreal float \
        -make libs \
        -make tools \
        -xplatform linux-arm-gnueabihf-g++ \
        -pch \
        -no-sse2 \
        -no-sse3 \
        -no-rpath \
        -no-tslib \
        -no-opengl \
        -no-cups \
        -qt-zlib \
        -widgets \
        -skip qt3d \
        -skip qtcanvas3d \
        -nomake examples \
        -no-use-gold-linker \

But it shows as below after run ./configure:

Note: Overriding option 'debug' with 'no' (was: 'yes')

Note: Also available for Linux: linux-clang linux-icc

Note: QtSerialBus: Cannot find linux/can.h and linux/can/raw.h Linux headers for socketCAN support.

Note: No wayland-egl support detected. Cross-toolkit compatibility disabled.

Note: The following modules are not being compiled in this configuration:
    webenginecore
    webengine
    webenginewidgets

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

What does 'Platform unsupported' mean ? Is there any tutorial for cross-compiling Qt with qtwebengine?

Silly question: are you sure you need QtWebEngine? If not, then you can just continue.

If you want to know why a platform is disabled, look through verbose output of configure - it will print a message when some build condition is not satisfied. Also, this document lists exact requirements an quirks of that module.

Sorry to bother. I do need QtWebEngine.
I found that pkg-config is needed to compile qtwebengine. But I encountered 'Cross compiling without sysroot. Disabling pkg-config' when I appended -pkg-config to ./configure. Is sysroot indispensable to cross compile qtwebengine? If so, does it mean that I need to mount the rootfs of my ARM board to host computer and cross compile all dependencies to that sysroot to get Qt with qtwebengine for ARM?

sierdzio

I don't know to be honest. I've never cross-compiled the web engine.

@sierdzio
Ok, Thanks. ;)

QtWebEngine mainly supports x86 and ARM architectures. The LoongArch 3A5000 processor is based on the Loongarch architecture, which is a CPU architecture independently developed by Loongarch. Since this architecture is different from the x86 and ARM architectures, there may be compatibility issues.
QtWebEngine is based on Chromium, and Chromium's cross-platform features focus on x86, x86-64, ARM, and ARM64 architectures. If Chromium does not provide support for the LoongArch architecture, then QtWebEngine may not be directly available on the Loongarch 3A5000.

@Thcale_yang said in QtWebEngine will not be built. Platform unsupported:

LoongArch 3A5000

Nobody was asking anything about this architecture. This thread is about QtWebEngine on ARM.
