qt5.4.1的imx6编译

2、到https://download.qt.io/archive/qt/5.4/5.4.1/single/下载源码包qt-everywhere-opensource-src-5.4.1.tar.gz

3、解压：

$ tar xzf qt-everywhere-opensource-src-5.4.1.tar.gz

$ cd qt-everywhere-opensource-src-5.4.1/

4、指定所用平台的arm架构以及交叉编译器：

$ vi qtbase/mkspecs/linux-arm-freescale-gnueabi-g++/qmake.conf

改成以下内容，实际应需要根据自己的开发环境作出相应改变：

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

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental gdb_dwarf_index xlib
QMAKE_INCREMENTAL_STYLE = sublib

QMAKE_CFLAGS_RELEASE   += -O2 -march=armv7-a  -mfloat-abi=softfp -mfpu=neon 

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

# modifications to g++.conf
QMAKE_CC                = arm-fsl-linux-gnueabi-gcc
QMAKE_CXX               = arm-fsl-linux-gnueabi-g++
QMAKE_LINK              = arm-fsl-linux-gnueabi-g++
QMAKE_LINK_SHLIB        = arm-fsl-linux-gnueabi-g++

# modifications to linux.conf
QMAKE_AR                = arm-fsl-linux-gnueabi-ar cqs
QMAKE_OBJCOPY           = arm-fsl-linux-gnueabi-objcopy
QMAKE_NM                = arm-fsl-linux-gnueabi-nm -P
QMAKE_STRIP             = arm-fsl-linux-gnueabi-strip
load(qt_config)

QMAKE_INCDIR += /opt/EmbedSky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/include
QMAKE_INCDIR += /opt/EmbedSky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/libX11/include
QMAKE_LIBDIR += /opt/EmbedSky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/lib
QMAKE_LIBDIR += /opt/EmbedSky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/qt-5.2.1-embedded-arm-MuliTCS/lib
QMAKE_LIBDIR += /opt/EmbedSky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/libX11/lib
QMAKE_LIBS+=-lXau -lxcb -lX11 -lX11-xcb

QMAKE_INCDIR_OPENGL_ES2=/opt/EmbedSky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/include
QMAKE_LIBDIR_OPENGL_ES2=/opt/EmbedSky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/lib
QMAKE_LIBS_OPENGL_ES2=-lglapi -lGLESv2 -lEGL

5、根据自己的实际需求配置Qt：

./configure -prefix /usr -xplatform linux-arm-freescale-gnueabi-g++ -confirm-license -opensource -release -make libs -optimized-qmake -pch -qt-sql-sqlit
e -qt-libjpeg -qt-libpng -qt-zlib -tslib -no-sse2 -no-openssl -no-nis -no-cups -no-glib  -no-separate-debug-info -nomake examples -nomake tools -nomake
tests -no-iconv -skip webkit -opengl es2 -verbose -no-xcb-xlib -qt-xcb  -qpa xcb
