Qt5.9.9交叉编译（带sqlite3、OpenSSL）

1、交叉编译工具链

��     这里ARM平台是ARM CortexA9的，一般交叉编译工具链demo板厂商都会提供，若未提供或想更换新版本的交叉编译工具链可参考以下方式获取。

1.1 下载适用于ARM CortexA9的交叉编译工具链

Linaro Releases下载gcc4的最新版xxxx-i686_arm-linux-gnueabihf.tar.xz

1.2 配置交叉编译工具链

1.2.1 解压下载好的工具链包

$ tar xvf gcc-linaro-4.9.4-2017.01-i686_arm-linux-gnueabihf.tar.xz

1.2.2 部署并配置工具链

拷贝到系统路径

$ sudo mv gcc-linaro-4.9.4-2017.01-i686_arm-linux-gnueabihf /usr/local/arm-linux-gnueabihf

配置环境变量

$ vim ~/.bashrc在文件末加入环境变量export PATH=/usr/local/arm-linux-gnueabihf/bin:$PATH使环境变量生效$ source ~/.bashrc

检验工具链是否正常使用

$ arm-linux-gnueabihf-gcc -v使用内建 specs。COLLECT_GCC=arm-linux-gnueabihf-gccCOLLECT_LTO_WRAPPER=/usr/local/arm-linux-gnueabihf/bin/../libexec/gcc/arm-linux-gnueabihf/4.9.4/lto-wrapper目标：arm-linux-gnueabihf配置为：/home/tcwg-buildslave/workspace/tcwg-make-release/label/docker-trusty-i386-tcwg-build/target/arm-linux-gnueabihf/snapshots/gcc-linaro-4.9-2017.01/configure SHELL=/bin/bash --with-mpc=/home/tcwg-buildslave/workspace/tcwg-make-release/label/docker-trusty-i386-tcwg-build/target/arm-linux-gnueabihf/_build/builds/destdir/i686-pc-linux-gnu --with-mpfr=/home/tcwg-buildslave/workspace/tcwg-make-release/label/docker-trusty-i386-tcwg-build/target/arm-linux-gnueabihf/_build/builds/destdir/i686-pc-linux-gnu --with-gmp=/home/tcwg-buildslave/workspace/tcwg-make-release/label/docker-trusty-i386-tcwg-build/target/arm-linux-gnueabihf/_build/builds/destdir/i686-pc-linux-gnu --with-gnu-as --with-gnu-ld --disable-libmudflap --enable-lto --enable-objc-gc --enable-shared --without-included-gettext --enable-nls --disable-sjlj-exceptions --enable-gnu-unique-object --enable-linker-build-id --disable-libstdcxx-pch --enable-c99 --enable-clocale=gnu --enable-libstdcxx-debug --enable-long-long --with-cloog=no --with-ppl=no --with-isl=no --disable-multilib --with-float=hard --with-mode=thumb --with-tune=cortex-a9 --with-arch=armv7-a --with-fpu=vfpv3-d16 --enable-threads=posix --enable-multiarch --enable-libstdcxx-time=yes --with-build-sysroot=/home/tcwg-buildslave/workspace/tcwg-make-release/label/docker-trusty-i386-tcwg-build/target/arm-linux-gnueabihf/_build/sysroots/arm-linux-gnueabihf --with-sysroot=/home/tcwg-buildslave/workspace/tcwg-make-release/label/docker-trusty-i386-tcwg-build/target/arm-linux-gnueabihf/_build/builds/destdir/i686-pc-linux-gnu/arm-linux-gnueabihf/libc --enable-checking=release --disable-bootstrap --enable-languages=c,c++,fortran,lto --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu --target=arm-linux-gnueabihf --prefix=/home/tcwg-buildslave/workspace/tcwg-make-release/label/docker-trusty-i386-tcwg-build/target/arm-linux-gnueabihf/_build/builds/destdir/i686-pc-linux-gnu线程模型：posixgcc 版本 4.9.4 (Linaro GCC 4.9-2017.01)

 2、SQLite交叉编译

    在后面交叉编译Qt源码的时候会用到

2.1 SQLite源码获取

SQLite Download Page下载最新版sqlite-autoconf-xxxx.tar.gz SQLite源码

2.2 交叉编码

解压源码$ tar -xvf sqlite-autoconf-3360000.tar.gz到源码路径$ cd sqlite-autoconf-3360000/配置编译$ ./configure CC=arm-linux-gnueabihf-gcc --host=arm-linux --prefix=/opt/arm_sqlite构建$ make安装$ sudo make install

 3、OpenSSL交叉编译

    Qt使用SSL时需用到OpenSSL库。

3.1 下载OpenSSL源码

Releases · openssl/openssl · GitHub下载OpenSSL_1_x_x最新版的，因为Qt5.9只支持OpenSSL_1的环境，这里下载OpenSSL_1_1_1k 

3.2 交叉编译

解压@ tar -xvf openssl-OpenSSL_1_1_1k.tar.gz进入到源码路径@ cd openssl-OpenSSL_1_1_1k/配置为静态编译，注意这里的/home/xxx是当前用户路径，xxx代表当前用户名@ ./config -fPIC no-shared no-asm --prefix=/home/xxx/arm_openssl --cross-compile-prefix=arm-linux-gnueabihf-修改Makefile@ vim Makefile搜索并将-m64删除编译@ make -j4安装@ make install

4、Qt交叉编译

4.1 下载Qt5.9.9源码

https://download.qt.io/archive/qt/5.9/5.9.9/single/下载Qt5.9.9源码

4.2 配置编译

 

解压qt源码包$ tar xvf qt-everywhere-opensource-src-5.9.9.tar.xz进入到源码目录$ cd qt-everywhere-opensource-src-5.9.9

4.2.1 配置qtbase/mkspecs/qmake.conf文件

## qmake configuration for building with arm-linux-gnueabihf-g++#MAKEFILE_GENERATOR      = UNIXCONFIG                 += incrementalQMAKE_INCREMENTAL_STYLE = sublibQT_QPA_DEFAULT_PLATFORM = linuxfb #eglfsQMAKE_CFLAGS_RELEASE += -O2 -march=armv7-aQMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-ainclude(../common/linux.conf)include(../common/gcc-base-unix.conf)include(../common/g++-unix.conf)QMAKE_INCDIR += /opt/arm_sqlite/include   #已编译的sqlite头文件路径QMAKE_LIBDIR += /opt/arm_sqlite/lib       #已编译的sqlite库路径QMAKE_INCDIR += /home/wzl/arm_openssl/include   #已编译的openssl头文件路径QMAKE_LIBDIR += /home/wzl/arm_openssl/lib       #已编译的openssl库路径# modifications to g++.confQMAKE_CC                = arm-linux-gnueabihf-gccQMAKE_CXX               = arm-linux-gnueabihf-g++QMAKE_LINK              = arm-linux-gnueabihf-g++QMAKE_LINK_SHLIB        = arm-linux-gnueabihf-g++# modifications to linux.confQMAKE_AR                = arm-linux-gnueabihf-ar cqsQMAKE_OBJCOPY           = arm-linux-gnueabihf-objcopyQMAKE_NM                = arm-linux-gnueabihf-nm -PQMAKE_STRIP             = arm-linux-gnueabihf-stripload(qt_config)

4.2.1 编写构建脚本

$ vim build.sh内容如下：#!/bin/sh./configure \-v \-prefix /home/wzl/workspace/Arm_Qt5.9.4 \-release \-opensource \-no-accessibility \-make libs \-xplatform linux-arm-gnueabi-g++ \-optimized-qmake \-pch \-sqlite \-qt-zlib \-openssl-linked \-no-sse2 \-no-openssl \-opengl es2 \-no-cups \-no-glib \-no-iconv \-no-pkg-config \-no-separate-debug-info \-skip qt3d \-skip qtcanvas3d \-skip qtdoc \-skip qtwaylandexit

4.2.3 编译

配置执行权限$ sudo chmod 777 build.sh$ ./build.sh
