准备

设置麒麟系统安全状态为Softmode （防止编译时出现权限不够问题）

sudo setstatus Softmode
getstatus

安装g++

sudo apt-get install build-essential

安装依赖库

开始编译

将源码包 QGIS-final-3_34_13.tar.gz 放入工作目录解压

tar -zxf QGIS-final-3_34_13.tar.gz
cd QGIS-final-3_34_13
mkdir build-master
cd build-master
ccmake ..

开启ccmake界面后按c configure完成后按g 生成makefile文件

输入 make 开始编译编译时间较长, 耐心等候
注意：每次出现问题需重新编译时需要删除掉 build-master目录下的所有文件（之前的编译缓存）不然会有意想不到的错误。

编译完成后运行 ./output/bin/qgis 打开编译好的qgis 出现启动界面完成

加速方案

cmake自定义编译选项

cmake ..\-GNinja \-DCMAKE_BUILD_TYPE=RelWithDebInfo \-DQt5_DIR:PATH=/opt/Qt/5.15.2/gcc_64/lib/cmake/Qt5 \-DUSE_CCACHE=ON \-DBUILD_WITH_QT6=OFF \-DWITH_DESKTOP=ON \-DWITH_ANALYSIS=ON \-DWITH_GUI=ON \-DWITH_QUICK=OFF \-DWITH_3D=OFF \-DWITH_GRASS7=OFF \-DWITH_GRASS8=OFF \-DSUPPRESS_QT_WARNINGS=ON \-DENABLE_TESTS=OFF \-DENABLE_MODELTEST=OFF \-DWITH_HANA=OFF \-DWITH_QGIS_PROCESS=OFF \-DWITH_QSPATIALITE=ON \-DWITH_QWTPOLAR=OFF \-DWITH_APIDOC=OFF \-DWITH_ASTYLE=OFF \-DWITH_BINDINGS=OFF \-DWITH_SERVER=OFF \-DWITH_SERVER_LANDINGPAGE_WEBAPP=OFF \-DWITH_ORACLE=OFF \-DWITH_PDAL=OFF \-DWITH_QTSERIALPORT=ON \-DWITH_QTWEBKIT=OFF \-DDISABLE_DEPRECATED=ON \-DAGGRESSIVE_SAFE_MODE=ON

然后

sudo ninja
sudo ninja install

问题和解决方案

geos版本过低

sudo ninja install

python找不到

sudo apt install python3.9

moc没有权限

sudo setstatus Softmode
