QtWebEngine will not be built. Platform unsupported
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. WARNING: QtWebEngine will not be built. Platform unsupported. WARNING: QtWebEngine will not be built. WARNING: QtPdf will not be built.
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?
I don't know to be honest. I've never cross-compiled the web engine.
Ok, Thanks. ;)
