# wgrib2模块编译报Could NOT find JPEG和Could NOT find Jasper错

#### 问题现象描述

NCEPLIBS构建安装中wgrib2模块报Could NOT find JPEG (missing: JPEG_LIBRARY JPEG_INCLUDE_DIR)和Could NOT find Jasper (missing: JASPER_LIBRARIES JASPER_INCLUDE_DIR JPEG_LIBRARIES)错，详细信息如下：


#### 关键过程、根本原因分析

无。


#### 结论、解决方案及效果

相应文件中未添加JASPER和JPEG的安装路径。

1. 修改“CMakeCache.txt”文件。

  a. 打开“CMakeCache.txt”文件。

```
vi /path/to/NCEPLIBS/NCEPLIBS-1.2.0/build/wgrib2/src/wgrib2-build/CMakeCache.txt
```


  b. 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=/path/to/JASPER/lib/libjasper.so
//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
```


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

```
make
```
