GDAL在VS2008 VC++中的配置
GDAL在VS2008 VC++中的配置
A prebuilt GDAL 1.4.1 library is available at:
http://download.osgeo.org/gdal/win32/1.4.1/gdalwin32dev141.zip
This should be unpacked on top of the executable package which includes the gdal14.dll:
http://download.osgeo.org/gdal/win32/1.4.1/gdalwin32exe141.zip
The dev package includes: * Include files in the gdalwin32-1.4.1\include directory. * An release (/MD /Ox) DLL (bin\gdal14.dll) and stub library (lib\gdal_i.lib).
The DLL and stub libraries are built with Visual Studio.NET 2003 (VC 7.1), which is likely required for any use of the C++ API. The libraries should be compatible with any win32 C/C++ compiler if only the GDAL/OGR C API is used. No debug version is offered.
1、下载GDAL库,新建VC++工程文件,在项目的属性对话框中找到{配置属性}→{C/C++}→{常规},在右侧的{附加包含目录}中,将下载到的GDAL库的include文件夹路径添加到这里:
2、在{配置属性}→{链接器}→{常规}的{附加库目录}中,将下载到的GDAL库的lib文件夹填写入:
3、在{配置属性}→{链接器}→{输入}中的{附加依赖项}中,填入lib文件夹下的gdal_i.lib文件名。
4、现在可以进行编译,但是在运行的过程中,会出现“gdal14.dll”缺失的问题。将下载到的gdalwin32exe141.zip中的bin文件夹下的gdal14.dll解压到编译成的debug文件夹下,运行成功。
测试代码:
