my (seemingly successful) attempt to install Anita's MovingPandas package

My notes on how to install MovingPandas from PyPI.

• These instructions do not require admin privs
• Everything is installed to a user's home directory, i.e.: /home/myself/usr/local.
• MovingPandas requires Cartopy and Proj
  • Cartopy requires Proj 4.8 or later
  • Cartopy requires Cython
  • pyproj requires Proj-6 or Proj-7
  • Proj-7 has compile issues
  • Proj-6,7 requires SQLite * SQLite may break mobilitydb

Most builds are similar to this:

    wget <somepackage>.tgz
    tar zxvf <somepackage>.tgz
    cd <somepackage>
    ./configure --prefix=/home/myself/usr/local <other flags as needed>
    make
    make install

Something somewhere tries to write to the system /tmp file. Point to somewhere that you have write access:

    export TMPDIR=/home/myself/tmp

Python3.7

Download, build, and install Python3.7; be sure to include --enable-shared along with the other configure flags.

Consider also installng PostgreSQL V11 (not v12), PostGIS, and MobilityDB.

SQLite3

PROJ requires SQLite3, but when I installed it, it broke mobilitydb. My temporary solution was to install SQLite3 off to the side just to get PROJ to compile.

The SQLite download page listed an 'amalgamation' package, but I didn't get that to work. I just compiled directly from sources.

    wget https://sqlite.org/2020/sqlite-src-3310100.zip
    unzip sqlite-src-3310100.zip
    cd sqlite-src-3310100
    ./configure --prefix=/home/myself/usr/local_sqlite
    make
    make TCLLIBDIR=/home/myself/usr/share_sqlite/usr/share/tcl8.5/sqlite3 install

(I have no idea why the make install insisted on a hardcoded TCLLIB, but I had to override that to get the install to work.)
TODO: figure out how to get MobilityDB and SQLite to behave together.

WAIT: maybe it was Proj-6 that required 'sqlite3 >= 3.11'.

__WAIT #2:__proj-5 compiled and installed, but it was TOO OLD, MUST use later

TODO: see if these instructions work with installed (SQLite 3.7.1) version, and that no d/l or install of SQLite is needed! A: correct, I think the SQLite dependency was for the version of Proj that wasn't used.

Proj-7.0.0

Note: Cartopy needs Proj-4.9 or later
Note: projpy needs Proj-6 or Proj-7
Note: Proj-6 and Proj-7 need SQLite3
Note: SQLite3 breaks MobilityDB
Note: Proj-6 needs datumgrid, Proj-7 needs data

    export PKG_CONFIG_PATH=/home/myself/usr/local/lib/pkgconfig/

    export SQLITE3_CFLAGS=-I/home/myself/usr/local_sqlite/include
    export SQLITE3_LIBS="-L/home/myself/usr/local_sqlite/lib -lsqlite3"

    wget https://download.osgeo.org/proj/proj-6.3.1.tar.gz
    tar zxvf proj-6.3.1.tar.gz

    wget https://download.osgeo.org/proj/proj-datumgrid-1.8.zip
    unzip proj-datumgrid-1.8.zip -d proj-6.3.1/data/

    cd proj-6.3.1
    ./configure --prefix=/home/myself/usr/local
    make
    make install

Seemed to go ok.

Cython

Install directly using pip:

    ~/usr/local/bin/pip3.7 install Cython --install-option="--no-cython-compile"

Running setup.py install for Cython ... done
Successfully installed Cython-0.29.15

Seemed to install ok.

Cartopy

Finally, we can now install cartopy.

I think that this step depends on PKG_CONFIG_PATH pointing to the place where the proj.pc file is located. (As already set above.)

    wget https://files.pythonhosted.org/.../Cartopy-0.17.0.tar.gz
    tar zxvf Cartopy-0.17.0.tar.gz
    cd Cartopy-0.17.0

    ~/usr/local/bin/python3.7 setup.py  build_ext --inplace -I/home/myself/usr/local/include -L/home/myself/usr/local/lib

    ~/usr/local/bin/python3.7 setup.py  install

Using /home/myself/usr/local/lib/python3.7/site-packages
Finished processing dependencies for Cartopy==0.17.0

It looks like it installed.

Note: sometimes install of cartopy was complaining about numpy being bad, but upon further analysis it seemed that the problem was really an invalid or missing Cython, and not anything to do with numpy.

MovingPandas

Ok, here goes...

    ~/usr/local/bin/pip3.7 install movingpandas

Successfully built movingpandas bokeh PyYAML tornado
Installing collected packages: ... movingpandas

and to see if it really worked:

    ~/usr/local/bin/python3.7
