使用yocto工具编译qt5.9.6总结

运行平台:OKMX6DL-C
编译平台:Ubuntu 14.04.6 LTS
编译工具:arm-poky-linux-gnueabi-gcc(gcc version 5.3.0 (GCC) )
qt源码:qt-everywhere-opensource-src-5.9.6.tar.xz

第4篇 交叉编译Qt 5.4.0

安装 SDK:

资料:飞凌开发板提供的OKMX6X-C_Linux4.1.15 用户资料\Linux\工具\fsl-imx-x11-glibc-x86_64-meta-toolchain-qt5-cortexa9hf-neon-toolchain-4.1.15-2.1.0.sh
(1)将fsl-imx-x11-glibc-x86_64-meta-toolchain-qt5-cortexa9hf-neon-toolchain-4.1.15-2.1.0.sh拷贝到虚拟机任意目录 ,执行:

./fsl-imx-x11-glibc-x86_64-meta-toolchain-qt5-cortexa9hf-neon-toolchain-4.1.15-2.1.0.sh

默认将会安装到/opt/fsl-imx-x11/目录下(这里安装到了/opt/fsl-imx-x11/4.1.15-2.1.0/)。
安装完成后 /opt/fsl-imx-x11/4.1.15-2.1.0/ 目录结构如下:

lin@ubuntu:/opt/lin$ ls
environment-setup-cortexa9hf-neon-poky-linux-gnueabisite-config-cortexa9hf-neon-poky-linux-gnueabi
sysroots
version-cortexa9hf-neon-poky-linux-gnueabi

environment-setup-cortexa9hf-neon-poky-linux-gnueabisite-config-cortexa9hf-neon-poky-linux-gnueabi 是环境初始化脚本。
(2)环境变量(注意空格):

. /opt/lin/environment-setup-cortexa9hf-neon-poky-linux-gnueabisite-config-cortexa9hf-neon-poky-linux-gnueabi

(3)译器是否安装成功:

 arm-poky-linux-gnueabi-gcc  -v 

安装依赖库

sudo apt-get install gcc-multilib g+±multilib
sudo apt install pkg-config
sudo apt install pkgconf

解压qt源码

$ xz -d  qt-everywhere-opensource-src-5.9.6.tar.xz         #解压文件      
$ tar xvf qt-everywhere-opensource-src-5.9.6.tar

删除旧版Qt

需要着重注意sysroot对应的cortexa9hf-neon-poky-linux-gnueabi目录下存在之前编译的旧Qt版本的动态库,必须进行清除操作,否则将会影响新版本Qt的编译。

cd /opt/lin/sysroots/cortexa9hf-neon-poky-linux-gnueabi/usr/lib$
sudo rm .libQt* -rf
sudo rm lib/qt5 -rf

修改qtbase/mkspecs/devices/linux-imx6-g++/qmake.conf

#
# qmake configuration for the Freescale iMX6 boards (single, dual and quad)
#
# The configuration below is set up for running with EGL on the framebuffer via
# the eglfs platform plugin and its eglfs_viv backend.

# Wayland is also fully functional out of the box. However, when writing Wayland
# *compositors* with Qt, the eglfs backend will have to be switched to
# eglfs_viv_wl by setting the QT_QPA_EGLFS_INTEGRATION environment variable.
#
# Below is an example configure line that assumes the SDK is in
# $HOME/imx6/toolchain. On device Qt is expected to be placed under
# /usr/local/qt5 whereas on the host 'make install' will copy the host tools and
# the target libraries to $HOME/imx6/qt5.
#
# ./configure -prefix /usr/local/qt5 -extprefix $HOME/imx6/qt5 -device linux-imx6-g++ \
#   -device-option CROSS_COMPILE=$HOME/imx6/toolchain/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi- \
#   -sysroot $HOME/imx6/toolchain/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi \

gpu库

至此EGLFS i.Mx6的支持是无法开启的,原因为sysroot中的EGL依赖库不是GPU版本,必须使用官方提供的GPU版本。gpu-viv-bin-mx6q-3.10.17-1.0.0.tar.gz

使用yocto工具编译qt5.9.6总结_第1张图片

tar  xvzf  gpu-viv-bin-mx6q-3.10.17-1.0.0.tar.gz 

解压完成后进入gpu-viv-bin-mx6q-3.10.17-1.0.0目录,该目录中有以下内容: 其中hardfp中的内容是我们需要的。把hardfp目录下的usr/lib/和include文件替换sysroot目录下的usr/lib 和usr/include中的文件,此目录是自己定义的,读者可以拷贝到其它目录下,只需要在后边修改Qt的编译配置文件的时候设置正确就可以了。~
