GPSTk 2.10 Python examples require installing GPSTk for Python. GPSTk 2.10 requires Python 2.7.

Install GPSTk for Python

1. Use Anaconda to switch to Python 2.7 by
   

   conda create -n py27 python=2.7
   conda activate py27
   conda install matplotlib
   

1. install minimal prereqs
   

   apt install g++ make cmake swig
   

1. Download gpstk source
   

   git clone --depth 1 https://github.com/SGL-UT/GPSTk
   cd GPSTk
   

1. Build & install. This takes several minutes, and emits a very large number of C++11 deprecation warnings
   

   ./build.sh -ue
   

Test GPSTk Python

1. get the example code
   

   git clone https://github.com/scivision/gpstk-examples-python
   

1. try the examples like:
   

   ./example1.py
   

Notes

If you get an error like

CMake Error at swig/PythonSetup.cmake:45 (string): string sub-command REGEX, mode MATCH needs at least 5 arguments total to command.

Create a file GPSTk/swig/CustomPythonSetup.cmake with contents (assuming python in ~/anaconda2)

set( PYTHONLIBS_FOUND "TRUE" )
set( PYTHON_LIBRARIES
    "$ENV{HOME}/anaconda2/lib/libpython2.7.so"
    CACHE FILEPATH "File Path to system python shared object library" )
set( PYTHON_INCLUDE_DIRS
    "$ENV{HOME}/anaconda2/include/python2.7"
     CACHE PATH "Directory Path to system python includes" )
