qt6.8.3 everywhere 交叉编译arm32

aiya12

我参考的是鲁班猫RK3566的教程编译32位手动修改编译器路径和编译架构,设备时3核cotext-a7

cmake_minimum_required(VERSION 3.18)
include_guard(GLOBAL)

set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR arm)
find_package(PkgConfig REQUIRED)
# 配置sysroot
set(TARGET_SYSROOT /home/qt/work/qt/sysroot)
set(CMAKE_SYSROOT ${TARGET_SYSROOT})
# 设置 搜索库的路径
set(ENV{PKG_CONFIG_PATH} $PKG_CONFIG_PATH:/usr/lib/arm-linux-gnueabihf/pkgconfig:${TARGET_SYSROOT}/usr/lib/arm-linux-gnueabihf/pkgconfig:arm-linux-gnueabihf/usr/share/pkgconfig/)
set(ENV{PKG_CONFIG_LIBDIR} /usr/lib/pkgconfig:/usr/share/pkgconfig/:${TARGET_SYSROOT}/usr/lib/arm-linux-gnueabihf/pkgconfig:${TARGET_SYSROOT}/usr/lib/pkgconfig)
set(ENV{PKG_CONFIG_SYSROOT_DIR} ${CMAKE_SYSROOT})

#查找GLESv2库
pkg_check_modules(GLESv2 QUIET glesv2)
if(GLESv2_FOUND)
  message(STATUS "包含目录: ${GLESv2_INCLUDE_DIRS}")
  message(STATUS "库文件: ${GLESv2_LIBRARIES}")
  message(STATUS "库目录: ${GLESv2_LIBRARY_DIRS}")
else()

  message("没找到库")
endif()

也尝试手动指定了库

set(GLESv2_INCLUDE_DIR ${GL_INC_DIR})
set(GLESv2_LIBRARY ${XCB_PATH_VARIABLE}/usr/lib/arm-linux-gnueabihf/libGLESv2.so)

但是最后都报错

CMake Error at qtbase/cmake/QtBuildInformation.cmake:534 (message):
  Feature "opengles2": Forcing to "ON" breaks its condition:

      NOT WIN32 AND NOT WATCHOS AND NOT QT_FEATURE_opengl_desktop AND GLESv2_FOUND

  Condition values dump:

      WIN32 = ""
      WATCHOS = "0"
      QT_FEATURE_opengl_desktop = "OFF"
      GLESv2_FOUND = "FALSE"

编译命令是

cmake ../qt-everywhere-src-6.8.3/ -GNinja -DCMAKE_BUILD_TYPE=Release  -DINPUT_opengl=es2 -DQT_BUILD_EXAMPLES=OFF -DQT_BUILD_TESTS=OFF -DQT_HOST_PATH=/home/qt/work/qt/ay_src/qt-host -DCMAKE_STAGING_PREFIX=/home/qt/work/qt/sysroot/opt/prefix -DCMAKE_INSTALL_PREFIX=/home/qt/work/qt/sysroot/opt/prefix -DCMAKE_TOOLCHAIN_FILE=/home/qt/work/qt/ay_src/tool_chain.cmake  -DQT_QMAKE_TARGET_MKSPEC=devices/linux-imx6-g++ -DQT_FEATURE_xcb=OFF -DFEATURE_xcb_xlib=OFF -DQT_FEATURE_xlib=OFF -DFEATURE_qtwebengine_build=OFF -DQT_FEATURE_eglfs=ON -DQT_FEATURE_drm=ON -DQT_QPA_DEFAULT_PLATFORM=eglfs -DGLESv2_INCLUDE_DIR=/home/qt/work/qt/sysroot/usr/include -DGLESv2_LIBRARY=/home/qt/work/qt/sysroot/usr/lib/arm-linux-gnueabihf/libGLESv2.so

请问一下 cortex-a7 3核 RAM:128MB 可以使用QT吗,还有就是这个是什么原因呢

确认下你这个SOC有没有GPU, 这个报错是因为在sysroot 下没有OpenGL ES 需要的GPU驱动库文件和头文件造成的报错。
