qt5.5.1交叉编译

1. 下载qt-everywhere-opensource-src-5.5.1.tar.gz.

2. 修改 :qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf  

   将编译器改为如下:

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

MAKEFILE_GENERATOR = UNIX
CONFIG += incremental
QMAKE_INCREMENTAL_STYLE = sublib

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

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

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

3. 执行:

./configure -release -opensource -xplatform linux-arm-gnueabi-g++ -prefix /work/disk2/QT/Qt-5.5.1/ -no-c++11 -qreal float 

4. make

make 的时候报错, painting/qpdf.cpp:2157:44: error

需要修改\work\disk2\QT\qt-everywhere-opensource-src-5.5.1\qtbase\src\gui\painting\qpdf.cpp

将其注释掉
