unsure of correct path for PROJ_DIR on ubuntu about pyproj

[grant-humphries]

Looking at this project's setup.py I gathered that path that PROJ_DIR is set to needs to have subfolders called 'lib' and 'include' so given where my proj.4 is installed that makes me think /usr may be the proper path to set the variable. However I gave PROJ_DIR that value and ran pip install -vvv pyproj, but the output from pip was identical to when I had the variable set to /usr/share/proj so I'm still not clear as to whether my proj.4 installation is being used

There are two additional undocumented environment variables: PROJ_LIBDIR and PROJ_INCDIR.

PROJ_LIBDIR - this is the path PROJ_DIR + '/lib' and PROJ_DIR + '/lib64'
PROJ_INCDIR - this is the path PROJ_DIR + '/include'

If set in the environment, that setting will be used over the defaults.

If you want to see where pyproj data files are installed, print the variable: pyproj.pyproj_datadir

Thanks for getting back to me. FWIW these are install locations of my proj.4 package:

/usr
/usr/lib
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/pkgconfig
/usr/lib/x86_64-linux-gnu/pkgconfig/proj.pc
/usr/lib/x86_64-linux-gnu/libproj.la
/usr/lib/x86_64-linux-gnu/libproj.a
/usr/include
/usr/include/org_proj4_PJ_Type.h
/usr/include/projects.h
/usr/include/org_proj4_PJ.h
/usr/include/geodesic.h
/usr/include/org_proj4_Projections.h
/usr/include/proj_api.h
/usr/share
/usr/share/doc
/usr/share/doc/libproj-dev
/usr/share/doc/libproj-dev/copyright
/usr/share/man
/usr/share/man/man3
/usr/share/man/man3/pj_init.3.gz
/usr/share/man/man3/geodesic.3.gz
/usr/lib/x86_64-linux-gnu/libproj.so
/usr/share/doc/libproj-dev/changelog.Debian.gz
/usr/share/doc/libproj-dev/NEWS.Debian.gz
/usr/share/man/man3/proj.3.gz

Do you have a recommendation as to how I should set the environment variables? It looks like setting PROJ_DIR to /usr would be about right, but there is no lib64 directory on my system. Maybe set PROJ_DIR to /usr and PROJ_LIBDIR to /usr/lib/x86_64-linux-gnu?

For a previous install I had PROJ_DIR set to /usr/share/proj and pyproj.data_dir was set to /usr/share/proj/share/proj

If you set PROJ_DIR to /usr for the library portion it would default to adding the directories /usr/lib and /usr/lib64 to search for the library.

Actually for Ubuntu 16.04 if you are using a default installation of PROJ.4, I'd recommend installing the Ubuntu repository package for pyproj.
$ apt install pyproj
Probably want to install it with administrative privileges, (sudo).
The Debian GIS maintainer, Bas, keeps on top of packaging.

I don't want to install this to my system python, so that solution isn't ideal for me. Thanks for your responses though, it sounds like pointing PROJ_DIR to /usr may be the correct setting, I'm going to go ahead and close the ticket
