centos7 安装 gdal

安装gdal前需先安装proj6，安装proj6前需先安装sqlite3

1、下载安装 sqlite3

安装proj需要先安装sqlite3，

sqlite3：

https://www.sqlite.org/download.html 下载sqlite3 安装包
tar xvfz sqlite-autoconf-3430200.tar.gz
cd sqlite-autoconf-3430200

配置及编译安装

./configure --prefix=/usr/local/sqlite3 --enable-rtree=yes
make && make install

2、下载安装 proj6

wget https://download.osgeo.org/proj/proj-6.3.0.tar.gz
或者 https://github.com/OSGeo/PROJ/releases 手动选择下载

yum install gcc-c++ libstdc++-devel

设置环境变量：

export PKG_CONFIG_PATH=/usr/local/proj6
export SQLITE3_CFLAGS="-I/usr/local/sqlite3/include"
export SQLITE3_LIBS="-L/usr/local/sqlite3/lib -lsqlite3"
export PATH=/usr/local/sqlite3/bin/:$PATH

tar -xvf proj-6.3.0.tar.gz
cd proj-6.3.0
./configure --prefix=/usr/local/proj6
make && make install

---

make时，如果遇到错误：bits/c++config.h: No such file or directory

cd /usr/include/c++/4.8.2/
mkdir x86_64-redhat-linux   #若没有则创建目录
cp -R i686-redhat-linux/bits x86_64-redhat-linux/   #将i686-redhat-linux目录下的bits拷贝至x86_64-redhat-linux下

---

make时出现错误，修改后要先 make clean 后再 make

3、下载安装 gdal

从 https://gdal.org/download.html# 下载
or wget https://github.com/OSGeo/gdal/releases/download/v3.5.2/gdal-3.5.2.tar.gz

export PATH=/usr/local/proj6/bin:$PATH #设置环境变量

tar -xvf gdal-3.5.2.tar.gz
cd gdal-3.5.2
./configure --prefix=/usr/local/gdal3 --with-python=python3 --with-proj=/usr/local/proj6
make && make install

最后这步 make 耗时会比较久。
编译完成后，将 GDAL 添加到系统路径中：

echo 'export PATH=/usr/local/gdal3/bin:$PATH' >> ~/.bashrc && source ~/.bashrc

最后，查看是否安装成功：

gdalinfo --version
