ubuntu交叉编译arm版本Qt

一、更新、安装基础依赖

sudo apt update && \
sudo apt upgrade -y && \
sudo apt install -y build-essential python

二、准备文件

1.新建目录

mkdir qt

2.下载文件

(1)gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.tar

网址

https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-linux-gnu/

点击"gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz"下载
配置

tar -xvf gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.tar && \
sudo cp -fr gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu /opt/ && \
str='export PATH=/opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin:"$"PATH' && \
sudo sh -c "echo $str >> /etc/profile" && \
source /etc/profile

重启后打开终端输入"aa"，连续按两次"Tab"键，出现如下表示成功:

aa-enabled                       aarch64-linux-gnu-cpp            aarch64-linux-gnu-gcc-nm         aarch64-linux-gnu-gfortran       aarch64-linux-gnu-objdump        aa-status

aarch64-linux-gnu-c++filt        aarch64-linux-gnu-gcc-ar         aarch64-linux-gnu-gdb-add-index  aarch64-linux-gnu-objcopy        aa-remove-unknown

(2)qt-everywhere-src-5.12.9.tar.xz

网址

https://download.qt.io/archive/qt/5.12/5.12.9/single/

点击" qt-everywhere-src-5.12.9.tar.xz"下载
下载后解压"qt-everywhere-src-5.12.9.tar.xz"文件

三、安装依赖

1.终端apt依赖

sudo apt install -y gperf \
bison \
flex \
llvm \
libxcb* \
libxslt1-dev \
ruby \
libssl-dev \
libcap-dev \
libxtst-dev \
libpci-dev \
libnss3-dev \
libclang-6.0-dev

2.修改一些配置文件

修改以下文件

gedit qt-everywhere-src-5.12.9/qtbase/mkspecs/linux-aarch64-gnu-g++/qmake.conf

增加以下内容(在QMAKE_INCREMENTAL_STYLE = sublib与include(…/common/linux.conf)之间)

QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE += -O2 -march=armv8-a -lts
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv8-a -lts

在文件中的"aarch64-linux-gnu"加上具体路径，最后文件

#
# qmake configuration for building with aarch64-linux-gnu-g++
#

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE += -O2 -march=armv8-a -lts
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv8-a -lts

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

# modifications to g++.conf
QMAKE_CC                = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc
QMAKE_CXX               = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++
QMAKE_LINK              = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++
QMAKE_LINK_SHLIB        = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++

# modifications to linux.conf
QMAKE_AR                = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-ar cqs
QMAKE_OBJCOPY           = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-objcopy
QMAKE_NM                = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-nm -P
QMAKE_STRIP             = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-strip
load(qt_config)

将文件夹移动至/opt

sudo cp -fr qt-everywhere-src-5.12.9 /opt/

四、configure

cd /opt/qt-everywhere-src-5.12.9

sudo ./configure \
-prefix /opt/Qt5.12.9-arm \
-confirm-license \
-opensource \
-release \
-make libs \
-xplatform linux-aarch64-gnu-g++ \
-pch \
-qt-libjpeg \
-qt-libpng \
-qt-zlib \
-no-opengl \
-no-sse2 \
-no-cups \
-no-glib \
-no-dbus \
-no-xcb \
-no-separate-debug-info

五、编译安装

1.编译

sudo make -j $(nproc)

2.安装

sudo make install

六、配置Qt环境

打开Qt
依次点击“工具”，“选项”，“Kits”
需要配置：“编译器”、“Qt Versions”、“Kits”
1.“编译器”：
点击“添加”，“GCC”，“C”
名称填写：“AArch64GCC”
编译器路径选择：“/opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc”
点击“Apply”
再点击“添加”，“GCC”，“C++”
名称填写：“AArch64G++”
编译器路径选择：“/opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++”
点击“Apply”
2.“Qt Versions”
点击“添加”
选择：“/opt/Qt5.12.9-arm/bin/qmake”
点击“Apply”
3.“Kits”
点击“Add”
