[GRASS-user] Unable to select EPSG code for location

RichTC · April 9, 2012, 8:00am

Hi,

After installing 6.4.2 from source, attempting to insert a spatial reference
system for a new location (/Select EPSG code for spatial reference system/)
was giving an error that it was unable to find EPSG codes at
/usr/local/share/proj/epsg

The configuration commands (--with-proj-share="/usr/share/proj/" ) did not
seem to make a difference?

My solution was to copy the proj directory and contents from /usr/share/proj
to to /usr/local/share
sudo cp -r /usr/share/proj /usr/local/share/

Has anyone else encountered this problem, or perhaps my configuration
options below need amending?

./configure \
--enable-debug \
--enable-largefile \
--with-libs=/usr/lib64 \
--with-geos=/usr/bin/geos-config/ \
--with-cxx \
--with-readline \
--with-freetype=yes \
--with-freetype-includes="/usr/include/freetype2/" \
--enable-largefile=yes \
--with-geos=yes \
--with-cairo \
--with-tcltk-includes="/usr/include/tcl8.5/" \
--with-wxwidgets \
--with-postgres=yes \
--with-postgres-includes="/usr/include/postgresql/" \
--with-sqlite=yes \
--with-python=yes \
--with-opengl-libs="/usr/include/GL" \
--with-ffmpeg=yes \
--with-ffmpeg-includes="/usr/include/libavcodec /usr/include/libavformat
/usr/include/libswscale" \
--with-lapack=yes \
--with-nls=yes \
--with-motif=yes \
--with-readline=yes \
--with-python=yes \
--with-proj-share="/usr/share/proj/" \

Cheers,
Richard

Please tell us on which operating system.

Please tell us how you installed PROJ4 (self compiled or package)?

It depends.

My solution was to copy the proj directory and contents from /usr/share/proj
to to /usr/local/share
sudo cp -r /usr/share/proj /usr/local/share/

That's likely no good idea and not needed.

Has anyone else encountered this problem, or perhaps my configuration
options below need amending?

./configure \

...

--with-proj-share="/usr/share/proj/" \

Tell us what exactly the problem is (copy paste of error).

Hi,

After installing 6.4.2 from source, attempting to insert a spatial reference
system for a new location (/Select EPSG code for spatial reference system/)
was giving an error that it was unable to find EPSG codes at
/usr/local/share/proj/epsg

At first I found this same problem.

I have proj and proj-devel installed by the package manager (yum on Scientific Linux 6) and GRASS 6.4.2 self compiled.
I double checked the ./configure line to make sure I had:
–with-proj-share=“/usr/share/proj”

Then I got the following output after running configure:

checking for location of External PROJ.4 includes…
checking for proj_api.h… yes
checking External PROJ.4 version… 470
checking for location of External PROJ.4 library…
checking for pj_get_def in -lproj… yes
checking for location of External PROJ.4 data files… /usr/share/proj
checking for /usr/share/proj/epsg… yes

Now, after compiling and installing, I still got the error message that Richard mentioned when I tried to create a Location with the wizard, but then, after choosing “Select EPSG code…” I had a window to choose the correct path to the epsg file. Only then it worked as expected.

Thanks,
Micha

The path is handled via GRASS_PROJSHARE:

[neteler@north wxpython]$ grep GRASS_PROJSHARE */*
./gui/wxpython/location_wizard/wizard.py: epsgdir =
utils.PathJoin(os.environ["GRASS_PROJSHARE"], 'epsg')
./gui/wxpython/core/settings.py: projFile =
PathJoin(os.environ["GRASS_PROJSHARE"], 'epsg')

which comes from

./lib/init/init.sh:if [ ! "$GRASS_PROJSHARE" ] ; then
./lib/init/init.sh: GRASS_PROJSHARE=CONFIG_PROJSHARE

which comes from

./lib/init/Makefile: -e \"s#CONFIG_PROJSHARE#$(PROJSHARE)#\" \
./lib/init/Makefile: -e \"s#CONFIG_PROJSHARE#$(PROJSHARE)#\" \

which comes from

configure:PROJSHARE=
configure: PROJSHARE="$with_proj_share"
configure:if test -z "$PROJSHARE" ; then
configure: PROJSHARE=/usr/local/share/proj

This is the --with-proj-share switch.

Hypothesis: No "make distclean" was done after PROJ4 installation?

I'm finding that the issue remains after re-installing PROJ from source and
running sudo make distclean.

Method:
Uninstalled package version of PROJ from system and installed from source as
per http://grass.osgeo.org/wiki/Compile_and_Install_Ubuntu but using latest
version of PROJ

sudo svn co http://svn.osgeo.org/metacrs/proj/branches/4.8/proj/
sudo wget -c http://download.osgeo.org/proj/proj-datumgrid-1.5.zip
sudo mv proj-datumgrid-1.5.zip /usr/local/src/proj/nad
cd /usr/local/src/proj/nad
sudo ./configure
sudo make
sudo make install
sudo make distclean

Then configure, make and make install of GRASS

./configure \
--with-tcltk-includes="/usr/include/tcl8.5/" \
--with-tcltk-libs="/usr/lib/tcl8.5" \
--enable-debug \
--enable-largefile \
--with-libs=/usr/lib64 \
--with-proj-share="/usr/share/proj/" \
--with-cxx \
--with-readline \
--with-freetype=yes \
--with-freetype-includes="/usr/include/freetype2/" \
--enable-largefile=yes \
--with-geos=yes \
--with-cairo \
--with-wxwidgets \
--with-postgres=yes \
--with-postgres-includes="/usr/include/postgresql/" \
--with-sqlite=yes \
--with-python=yes \
--with-opengl-libs=/usr/include/GL \
--with-ffmpeg=yes \
--with-ffmpeg-includes="/usr/include/libavcodec /usr/include/libavformat
/usr/include/libswscale" \
--with-lapack=yes \
--with-nls=yes \
--with-motif=yes \
--with-readline=yes \
--with-python=yes \
--with-proj=yes \
--with-blas --with-lapack --with-cxx \

Resolved.

Run the command 'make distclean' in the GRASS installation directory
(grass-6.4.2), then then ./configure, make and make install. The path to the
EPSG codes in then /usr/share/proj/epsg
