Ubuntu 18.10 下安装 QT5.6.2 交叉编译环境记录
1.安装交叉编译工具链
arm-linux-gcc-4.4.3.tar.gz
2.安装 qt-everywhere-opensource-src-5.6.2.tar.gz
2.1解压
tar -xvf qt-everywhere-opensource-src-5.6.2.tar.gz 2.2 配置
2.2.1 编译 tslib(tslib-1.4.tar.gz)
./autogen.sh
echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache
./configure --host=arm-linux --prefix=$(pwd)/_install --cache-file=arm-linux.cache
make && make install 2.2.2
复制一份 qtbase/mkspecs/linux-arm-gnueabi-g++ 重命名为qtbase/mkspecs/linux-arm-qt
2.2.3
修改 linux-arm-qt 目录下的 qmake.conf
#
# qmake configuration for building with arm-linux-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)
#add by
QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE += -O2 -march=armv5te # 需要修改对应架构
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv5te # 需要修改对应架构
# modifications to g++.conf
QMAKE_CC = arm-linux-gcc
QMAKE_CXX = arm-linux-g++
QMAKE_LINK = arm-linux-g++
QMAKE_LINK_SHLIB = arm-linux-g++
# modifications to linux.conf
QMAKE_AR = arm-linux-ar cqs
QMAKE_OBJCOPY = arm-linux-objcopy
QMAKE_NM = arm-linux-nm -P
QMAKE_STRIP = arm-linux-strip
load(qt_config)
2.2.4 配置脚本

2.3 make
2.4 make install3.安装 qt-opensource-linux-x86-5.6.2.run
./ qt-opensource-linux-x86-5.2.1.run4.配置QtCreator, 主要设置arm 交叉编译工具和qmake
**********Tools--->Options--->Build&Run--->Comoilers 添加 arm-linux-gcc 路径
**********Tools--->Options--->Build&Run--->Qt Versions 添加 qmake 路径
**********Tools--->Options--->Build&Run--->Kits
5.复制 Qt 库、arm-linux-gcc 库、tslib 库 到 arm机器

1.编译QT 5.6.2 出现
file not recognized: file truncated。
解决：删除文件目录下的 .o 文件
2.第三方库 tslib 和 QT 自带的evdev 只需要使能一个即可
-no-evdev 关闭QT 自带evdev库
3. libiconv-1.14.tar.gz
需要编译此库文件
