myGPSTk_python: A C++ repository from malliwi88

GPSTk Version 2.5 (gpstk-2.5.src+Modif)

IMPORTANT

Always you MUST BE change this line on file python/bindings/swig/CMakeLists.txt

set (HOME "/home/<-YOUR-PC-NAME-HERE->")

For my case whole procedure - Assumes that Machine name is **wallas** and the home foldes absolute path is /home/wallas/

Esta versión ya esta modificada con los siguientes ajustes

modify file python/bindings/swig/gpstk.i

comment line 15 (doc.i)

	//%include "doc/doc.i"

in section 4 just after toGloEphemeris

   %rename (toGPSEphemeris) *::operator GPSEphemeris() const;

modify file python/bindings/swig/CMakeLists.txt

add the following lines at begin of file (use .so instead of .dylib if on linux)

set (HOME "${HOME}")
SET(PYTHON_INCLUDE_PATH "${HOME}/anaconda3/envs/py27/include/python2.7/")
SET(PYTHON_LIBRARIES "${HOME}/anaconda3/envs/py27/lib/libpython2.7.so")
SET(PYTHON_LIBRARY "${HOME}/anaconda3/envs/py27/lib/libpython2.7.so")

Installation of PCRE

sudo apt-get install libz-dev libbz2-dev liblzma-dev libreadline-dev

Compile and Install PCRE by running the following commands:

	./configure --prefix=/usr                     \
		    --docdir=/usr/share/doc/pcre-8.42 \
		    --enable-unicode-properties       \
		    --enable-pcre16                   \
		    --enable-pcre32                   \
		    --enable-pcregrep-libz            \
		    --enable-pcregrep-libbz2          \
		    --enable-pcretest-libreadline     \
		    --disable-static                 &&
	make

To test the results, issue:

	make check.

Now, as the root user:

	make install                     &&
	mv -v /usr/lib/libpcre.so.* /lib &&
	ln -sfv ../../lib/$(readlink /usr/lib/libpcre.so) /usr/lib/libpcre.so

Compile and Install SWIG

If you plan to run the tests, some fixes are needed for using Perl-5.26:

	sed -i 's/\$(PERL5_SCRIPT/-I. &/' Examples/Makefile.in &&
	sed -i 's/\$command 2/-I. &/' Examples/test-suite/perl5/run-perl-test.pl

Install SWIG by running the following commands:

	./configure --prefix=/usr                      \
		    --without-clisp                    \
		    --without-maximum-compile-warnings &&
	make

To test the results, issue: make -k check TCL_INCLUDE= GOGCC=true. The (un)setting of the two variables GOGCC and TCL_INCLUDE is necessary, since they are not correctly set by configure. The tests are only executed for the languages installed on your machine, so the disk space and SBU values given for the tests may vary, and should be considered as mere orders of magnitude. If you have Python-2.7.15 installed, the Python-3 tests are not run. You can run tests for Python-3 by issuing PY3=1 make check-python-examples followed by PY3=1 make check-python-test-suite. According to SWIG's documentation, the failure of some tests should not be considered harmful.
Now, as the root user:

	make install &&
	install -v -m755 -d /usr/share/doc/swig-3.0.12 &&
	cp -v -R Doc/* /usr/share/doc/swig-3.0.12

Install Anaconda

you can obtain a Anaconda installer for your SO from HERE or you can:

Anaconda 3.5

for 64bits

wget https://repo.continuum.io/archive/Anaconda3-4.2.0-Linux-x86_64.sh
bash Anaconda3-4.2.0-Linux-x86_64.sh

for 32bits

wget https://repo.continuum.io/archive/Anaconda3-4.2.0-Linux-x86.sh
bash Anaconda3-4.2.0-Linux-x86.sh

Anaconda 2.7

Create a anaconda enviroment

It's with the propose that you have a isolated GPSTk development enviroment

conda create -n py27 python=2.7 notebook jupyter nbconvert numpy scipy matplotlib ipykernel sympy pyproj numba pandas pytables
source activate py27
pip install nvector

run compile and install script:

(on MACOS DO NOT INSTALL AS ROOT!!! install as user and it will install under $HOME/.local)

on LINUX:

bash script_gpstk.sh -bc -p -l ~/anaconda3/envs/py27/lib/python2.7/site-packages -s ~/gpstk-2.5

on MACOS:

./script_gpstk.sh -c -p -s /opt/gpstk

Add lines to bashrc (BUT NOT AT COMPILE TIME)

make sure the following variables are defined in your bashrc (BUT NOT AT COMPILE TIME), add this lines to nano ~/.bashrc

export LD_LIBRARY_PATH=/home/wallas/gpstk-2.5/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/home/wallas/anaconda3/envs/py27/lib:$LD_LIBRARY_PATH

Install python bindigns

cd ~/gpstk-2.5.src/python/bindings/swig/install_package
python setup.py install --prefix=~/anaconda3/envs/py27

Verify your installation

you can see gpstk in the list of packages

conda list

check if the file libgpstk.so library is on ${HOME}/anaconda3/envs/py27/lib

locate libgpstk.so

If file isn't in this path, copy it from ${HOME}/gpstk-2.5/lib/libgpstk.so to ${HOME}/anaconda3/envs/py27/lib

cp ${HOME}/gpstk-2.5/lib/libgpstk.so ${HOME}/anaconda3/envs/py27/lib

Run example codes

The compilation procedure creates a folder build*, in my case build-wallas-pc-

cd build-wallas-pc-/swig/install_package/examples
python example1.py

the results of code example1.py
