Мобильная версияЯ пытаюсь перекрестно компилировать QT 6.8.3 для Raspberry Pi 4 (64-разрядная книжная червя Raspberry Pi OS) от хост-машины Ubuntu 22.04. Конечная цель состоит в том, чтобы построить QgroundControl .
Текущее состояние:
после обширного устранения неполадок (включая создание пользовательского pkgconf , тщательного создания Sysroot и подробного Cmake Toolchain , я имею управление, чтобы получить Complective Sciplure. Он генерирует файлы сборки и отчеты: < /p>

My Setup Details:
Host System: Ubuntu 22.04
Target System: Raspberry Pi 4, Raspberry Pi OS Bookworm (64-bit)
Qt Version: 6.8.3 (source from qt-everywhere-src-6.8.3.tar.xz)
Cross-Compiler Toolchain (Host): gcc-aarch64-linux-gnu and g++-aarch64-linux-gnu (version 11.4.0, default from Ubuntu 22.04 apt).
Host Qt: Qt 6.8.3 installed via online installer at ~/Qt/6.8.3/gcc_64 (for host tools).
Sysroot (Host):
Located at ~/rpi-sysroot.
Created by rsync --delete -avz copying /lib, /usr/lib, /usr/include, /usr/lib/aarch64-linux-gnu/pkgconfig, and /usr/share/pkgconfig from the fully updated Pi (after all dependencies below were installed).
Symlinks fixed using sysroot-relativelinks.py.
Confirmed ~/rpi-sysroot/usr/include/aarch64-linux-gnu/bits/wchar2-decl.h (and stdio2-decl.h) exist.
Custom pkgconf (Host):
pkgconf v2.1.1 built from source.
Configured with: ./configure --prefix=/usr/local/cross-pkgconf --with-sysroot-dir=/home/jarvis/rpi-sysroot --with-pkg-config-dir=/home/jarvis/rpi-sysroot/usr/lib/aarch64-linux-gnu/pkgconfig:/home/jarvis/rpi-sysroot/usr/share/pkgconfig --disable-shared --enable-static
Installed to /usr/local/cross-pkgconf/bin/pkgconf.
This custom pkgconf successfully finds gst-play-1.0 (with a manually created .pc file) when tested directly with debug flags.
Manual gst-play-1.0.pc on Pi (and in Sysroot):
Created at /usr/lib/aarch64-linux-gnu/pkgconfig/gst-play-1.0.pc on the Pi (and synced to sysroot) as it was missing. Content:
Code snippet
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib/aarch64-linux-gnu
includedir=${prefix}/include/gstreamer-1.0
Name: GStreamer Playback Library
Description: GStreamer Playback Library
Version: 1.22.0 # Matched to Pi's GStreamer version
Requires: gstreamer-1.0 >= 1.22.0, gstreamer-video-1.0 >= 1.22.0
Libs: -L${libdir} -lgstplay-1.0
Cflags: -I${includedir}
Comprehensive Dependencies on Pi:
Installed an extensive list of -dev packages on the Pi, including libc6-dev, all GStreamer plugins (base, good (runtime), bad, ugly (runtime), libav), EGL/GLES2/Mesa/DRM/GBM, XCB (many specific dev packages), font/image libs, protobuf-compiler, libprotobuf-dev, etc. ccache has been purged from the host.

provense whip2 speakers in in fasters in valles in in sufficers). Само обнаружение не удалось, или когда впервые появилась эта ошибка/... выходы CmakeError.log и компиляции показали, что кросс-компилятор пытался включить стандартные заголовки библиотеки C ++ из хост-системы (например,/usr/include/x86_64-linux-gnu/c ++/11/...) во время внутренней проверки Cmake's Internal Trest. Это указывает на загрязнение включающих путей, несмотря на Sysroot Settings. Файл битов/wchar2-decl.h существует в правильном пути, специфичной для архитектуры в Sysroot (~/rpi-sysroot/usr/include/aarch64-linux-gnu/bits /).
Файл инструментов устанавливает cmake_sysroot и adds-sysroot = $ {cmake_sysroot_sysroot_sysroot_sysroot_sysroot_sysroot_sysroot. Cmake_cxx_flags_init. Линия компиляции также включает пути -исистемные пути, указывающие на Sysroot. However, the earlier CMakeError.log observation about host C++ stdlib headers being included (e.g., from /usr/include/x86_64-linux-gnu/c++/11) during some compilation steps suggests that the compiler's include search mechanism is not being strictly confined to the sysroot for all types of includes (especially C standard library internal bits/... files and potentially C++ standard library Заголовки).
Какие конкретные переменные cmake, настройки инструментов или настройки QT необходимы для обеспечения исключительно кросс-компилятора и правильного использования Sysroot для разрешения всех стандартных библиотеков, включая эти внутренние биты/... Заголовки и стандартные заголовки C ++, и полностью избегает хост-системы во время фактической фазы строительных файлов qt-источников?>
