qt5.9.8 IMX 平台编译

1、与QT平行目录创建一个文件夹qt5-build，进行shadow build

配置configure脚本如下：

../qt-everywhere-opensource-src-5.9.8/configure -prefix /home/wangll/practice/QT/qt \

-opensource \

-release \

-no-pch \

-confirm-license \

-xplatform arm-poky-linux-gnueabi-g++ \

-qt-zlib \

-no-iconv \

-no-gif \

-qt-libjpeg \

-no-opengl \

-skip qtdeclarative \

-skip qtquickcontrols \

-skip qtquickcontrols2 \

-no-qml-debug \

-no-cups \

-no-glib \

-no-dbus \

-no-rpath \

-no-sse2 -no-sse3 -no-ssse3 -no-sse4.1 -no-sse4.2 \

-no-avx \

-no-openssl \

-nomake tools \

-qreal float \

-qt-libpng \

-sysroot /data/toolchain/imx-a7/sysroots/cortexa7hf-vfp-neon-poky-linux-gnueabi \

-nomake examples \

-I /data/toolchain/imx-a7/sysroots/cortexa7hf-vfp-neon-poky-linux-gnueabi/usr/include/ -L /data/toolchain/imx-a7/sysroots/cortexa7hf-vfp-neon-poky-linux-gnueabi/usr/lib/

 

2、创建IMX平台的目录：

qt-everywhere-opensource-src-5.9.8/qtbase/mkspecs/arm-poky-linux-gnueabi-g++

3、在目录arm-poky-linux-gnueabi-g++下，创建并修改qmake.conf 如下：

#

# qmake configuration for building with arm-linux-gnueabi-g++

#

 

MAKEFILE_GENERATOR = UNIX

CONFIG += incremental

QMAKE_INCREMENTAL_STYLE = sublib

QT_QPA_DEFAULT_PLATFORM = linuxfb

QMAKE_CFLAGS_RELEASE += -O2 -march=armv7-a -mfloat-abi=hard

QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a -mfloat-abi=hard

 

include(../common/linux.conf)

include(../common/gcc-base-unix.conf)

include(../common/g++-unix.conf)

 

# modifications to g++.conf

QMAKE_CC = arm-poky-linux-gnueabi-gcc

QMAKE_CXX = arm-poky-linux-gnueabi-g++

QMAKE_LINK = arm-poky-linux-gnueabi-g++

QMAKE_LINK_SHLIB = arm-poky-linux-gnueabi-g++

 

# modifications to linux.conf

QMAKE_AR = arm-poky-linux-gnueabi-ar cqs

QMAKE_OBJCOPY = arm-poky-linux-gnueabi-objcopy

QMAKE_NM = arm-poky-linux-gnueabi-nm -P

QMAKE_STRIP = arm-poky-linux-gnueabi-strip

load(qt_config)

 

4、在目录arm-poky-linux-gnueabi-g++下创建文件qplatformdefs.h，并添加内容如下：

#include "../linux-g++/qplatformdefs.h"
