关键过程、根本原因分析

无。

结论、解决方案及效果

需要安装部署JPEG和JASPER。

1. 安装JPEG并导入环境变量。

   cd /path/to/JPEG
   git clone git://github.com/LuaDist/libjpeg.git
   cd libjpeg/
   git branch
   git checkout 6c0fcb8
   ./configure --prefix=/path/to/JPEG
   make
   make install
   export PATH=/path/to/JPEG/bin:$PATH
   export LD_LIBRARY_PATH=/path/to/JPEG/lib:$LD_LIBRARY_PATH

2. 安装JASPER并导入环境变量。

   cd /path/to/JASPER
   wget https://www.ece.uvic.ca/~frodo/jasper/software/jasper-1.900.2.tar.gz
   tar -zxvf jasper-1.900.2.tar.gz
   cd jasper-1.900.2/
   ./configure --prefix=/path/to/JASPER
   make all install
   export PATH=/path/to/JASPER/bin:$PATH
   export LD_LIBRARY_PATH=/path/to/JASPER/lib:$LD_LIBRARY_PATH

3. 修改“/g2/src/g2-build/CMakeCache.txt”文件。
   1. 打开“/g2/src/g2-build/CMakeCache.txt”文件。

      vi /path/to/NCEPLIBS/NCEPLIBS-1.2.0/build/g2/src/g2-build/CMakeCache.txt

   2. 按“i”进入编辑模式，添加JASPER和JPEG的安装路径。

      //Path to a file.
      JASPER_INCLUDE_DIR:PATH=/path/to/JASPER/include/
      //Path to a library.
      JASPER_LIBRARY_DEBUG:FILEPATH=/path/to/JASPER/lib/
      //Path to a library.
      JASPER_LIBRARY_RELEASE:FILEPATH=JASPER_LIBRARY_RELEASE-NOTFOUND
      //Path to a file.
      JPEG_INCLUDE_DIR:PATH=/path/to/JPEG/include
      //Path to a library.
      JPEG_LIBRARY_DEBUG:FILEPATH=/path/to/JPEG/lib
      //Path to a library.
      JPEG_LIBRARY_RELEASE:FILEPATH=JPEG_LIBRARY_RELEASE-NOTFOUND

   3. 修改后按“Esc”键，输入:wq!，按“Enter”保存并退出编辑。
4. 重新编译。

   make
