Compiling OCSSW

Instructions for CentOS 7

The binaries that we distribute for linux were built on CentOS 6 using gcc 5.3.1 and run without recompiling. We provide the VIIRS libraries since this code is not yet open source.

1. Install CentOS 7
2. Install cmake 3.11 (the binaries from CMake work fine)

3. Get a newer compiler.  This gives us gcc-9.3.1

   yum install centos-release-scl
   yum install devtoolset-9
   yum install bison flex zlib-devel.x86_64 libX11-devel.x86_64 patch
   scl enable devtoolset-9 bash
   yum install python3
   pip3 install requests
   

4. Download install_ocssw and manifest.py to your home directory.

5. Install OCSSW binaries and source

   cd $HOME
   chmod +x install_ocssw.py
   ./install_ocssw.py -i ocssw -t 2020.2 --benchmark --src
   export OCSSWROOT=~/ocssw
   source $OCSSWROOT/OCSSW_bash.env
   

6. Build the third party libraries

   cd $OCSSWROOT/opt
   rm -rf bin include lib share
   cd src
   ./BuildIt.py
   

7. Build OCSSW

   cd $OCSSWROOT/ocssw-src
   mkdir build
   cd build
   cmake ..
   make -j 20 install
   

8. Run the benchmark

   cd $OCSSWROOT/benchmark
   ./seadas_benchmark.bash
