linux下gdal的python包的安裝

由於python包是從C++包編譯出來的，所以需要先下載源碼進行編譯安裝。
1. gdal下載
http://download.osgeo.org/gdal/CURRENT/
sudo ./configure --with-python --with-geos=geos-config的路徑
sudo make
sudo make install

 

注：安裝失敗重新編譯之前，使用make clean清除一下上次的內容。

 

2. 然后進入到swig/python目錄下
sudo python setup.py build
sudo python setup.py install

錯誤排解

1. ImportError: No module named _gdal

使用sudo find / -name gdal.py查找所在位置

然后用import sys;sys.path查看是否包含當前路徑，若不包含，添加到路徑中

 

2. ImportError: libgdal.so.20: cannot open shared object file: No such file or directory

查找該文件所在路徑

sudo find / -name libgdal.so.20

將路徑添加到~/.bashrc中

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

 

3. ERROR 6: GEOS support not enabled.

ogr庫依賴GEOS包，需要首先安裝GEOS，然后再安裝gdal。詳細可參見參考文章（http://scigeo.org/articles/howto-install-latest-geospatial-software-on-linux.html#gdal）.

一定要下載3.5.0,因為3.4版本有bug。http://download.osgeo.org/geos/geos-3.5.0.tar.bz2

 

cd /opt/source
wget http://download.osgeo.org/geos/geos-3.5.0.tar.bz2
tar xvjf geos-3.3.8.tar.bz2 
cd geos-3.3.8
mkdir build
./configure --prefix=/opt/source/geos-3.5.0/build --enable-python
# compile
make -j$threads
# check compilation result (passes on Ubuntu; may get errors on CentOS, but probably still ok)
make check
# install into build dir
make install
# check install
./build/bin/geos-config --version
