Conclusion and Solution

Install and deploy JPEG and JASPER.

1. Install JPEG and import the environment variables.

   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. Install JASPER and import the environment variables.

   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. Modify the /g2/src/g2-build/CMakeCache.txt file.
   1. Open the /g2/src/g2-build/CMakeCache.txt file.

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

   2. Press i to enter the edit mode and add the JASPER and JPEG installation paths.

      //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. Press Esc, type :wq!, and press Enter to save the file and exit.
4. Perform the compilation again.

   make
