在Linux下，使用Qt开发完一个项目后，需要将项目发布到其他机器上，如果手动操作，需要安装Qt，配置环境变量，编译项目，打包项目，非常麻烦，因此，写了一个一键发布脚本，可以自动完成上述操作。

参考

原理参考 南理汉子的如何打包我们用 Qt 写的软件 - Linux 篇 一文, 感谢!

假设软件为 myapp, 目录为~/bin, Qt 安装目录为 /opt/Qt/5.12.8/gcc_64
总结起来就是:

1. 运行ldd.sh myapp
2. 将ldd.sh拷贝到 /opt/Qt/5.12.8/gcc_64/plugin/platforms 目录 执行 ldd.sh libqxcb.so
3. cp -R /opt/Qt/5.12.8/gcc_64/plugin/platforms/lib/* ~/bin/lib/
4. cp -R /opt/Qt/5.12.8/gcc_64/plugin/platforms ~/bin/
5. 如果有数据库, 则 cp -R /opt/Qt/5.12.8/gcc_64/plugin/sqldrivers ~/bin/

一键脚本

不废话,使用方法

./onekeydeploy.sh myapp
#完成后运行 
./myapp.sh

脚本如下(文末可下载)

#!/bin/bash


# 获取所有的 libqxcb.so路径
qxcbs=`locate libqxcb.so`
numOfqxcbs=`locate libqxcb.so | wc -l`
#echo ${qxcbs}



# 如果有多个libqxcb.so, 则提示
if [ $numOfqxcbs -ne 1 ]; then
	cindex=0
	for xcb in $qxcbs
	do  
		((cindex++))
		echo $cindex $xcb	
	done

	echo ""
	echo   "choose the serial of libqxcb.so :" 
	read serial
fi


#根据输入的序号, 获取对应的libqxcb.so路径
cindex=0
for i in $qxcbs
do  
	qcxb=$i
	((cindex++))
	if [ ${cindex} -eq ${serial} ]; then
		break
	fi	
done

echo "libqxcb is:" $qcxb 
echo ""

# 当前路径下的libs目录不存在,则创建
LibDir=$PWD"/libs"
if [ ! -d "$LibDir" ]; then
    $(mkdir $LibDir)
fi


#获取额外的Qt 库路径
Target=$1
lib_array=($(ldd $Target | grep -o "/.*" | grep -o "/.*/[^[:space:]]*"))

echo "extra Qt lib is: $lib_array"


# 判断是否需要sqldrivers
sql="Sql"
needSql=0
for Variable in ${lib_array[@]}
do
    cp "$Variable" $LibDir
	if [[ $Variable == *$sql* ]]
	then
		needSql=1
	fi
done

if [ ${needSql} -eq 1 ]; then
	echo "need sql ${needSql}"
fi


echo "copy $1 libs finshed"
echo "========================"

xcb_array=($(ldd $qcxb | grep -o "/.*" | grep -o "/.*/[^[:space:]]*"))
for Variable in ${lib_array[@]}
do
    cp "$Variable" $LibDir
done


echo " "
echo "copy all  libs of '$qcxb'  finshed"
echo ">>>>>>>>>>>>>>>>>>>>>>>>>>>"


# 拷贝platforms目录到当前文件夹下
platforms="$(dirname "$qcxb")"
echo "paltforms dir is : $platforms"

cp -r $platforms  $PWD

if  [ "$needSql" -eq 1 ];
then
	sqldrivers="$(dirname "$platforms")/sqldrivers"
	cp -r $sqldrivers $PWD
	echo " "
	echo "copy $sqldrivers finshed"
	echo ">>>>>>>>>>>>>>>>>>>>>>>>>>>"
fi

# 删除platforms下冗余的lib目录
redundancyLib=$PWD/platforms/libs
rm -rf $redundancyLib

# 生成当前可执行文件对应的 .sh脚本 

echo "#!/bin/sh


appname=\`basename \$0 | sed s,\.sh\$,,\`
dirname=\`dirname \$0\`


tmp=\"\${dirname#?}\"
if [ \"\${dirname%\$tmp}\" != \"/\" ]; then
dirname=\$PWD/\$dirname
fi

LD_LIBRARY_PATH=\$dirname/libs:\$LD_LIBRARY_PATH

export LD_LIBRARY_PATH
cd \$dirname/

\$dirname/\$appname \"\$@\"
"> $1.sh

echo ""
echo "#################################################"
echo " generate '${1}.sh'  start up script finshed"

更多打包

1. 去linuxdeployqt的主页下载linuxdeployqt

export PATH=/opt/Qt/5.15.2/gcc_64/bin/:$PATH
export LIB_PATH=/opt/Qt/5.15.2/gcc_64/lib:$LIB_PATH
export PLUGIN_PATH=/opt/Qt/5.15.2/gcc_64/plugins:$PLUGIN_PATH
export QML2_PATH=/opt/Qt/5.15.2/gcc_64/qml:$QML2_PATH
export LD_LIBRARY_PATH=/opt/Qt/5.15.2/gcc_64/lib

2. 执行打包

   ./linuxdeployqt myapp -appimage
