[GRASS-dev] GDAL's GRASS plugin

Hi,

just compiled latest GDAL from CVS + GRASS plugin 1.3.1.2.

two issues:

1) probably just README needs updating or I need to read it better?

cd gdal/frmts/grass/pkg
./configure ...

make: *** No rule to make target `grass57dataset.o', needed by `gdal_GRASS.so'. Stop.

(I assume this needs re./configure --with-grass= after GRASS is built)

[build GRASS with new GDAL libs]

2) gdal installs a broken & unwanted symlink:

downloaded GRASS plugin 1.3.1.2,

./configure
make
[ok]

# make install

install -d /usr/local/lib/gdalplugins
install: cannot create directory `/usr/local/lib/gdalplugins': File exists
make: *** [install] Error 1

# ls /usr/local/lib/gdalplugins -l
lrwxrwxrwx 1 root staff 20 2005-10-24 16:17 /usr/local/lib/gdalplugins -> /usr/lib/gdalplugins

(/usr/lib/gdalplugins doesn't exist)

if I do:

# rm /usr/local/lib/gdalplugins
# mkdir /usr/local/lib/gdalplugins

then

# make install

it works,
$ gdalinfo --formats | grep GRASS
  GRASS (ro): GRASS Database Rasters (5.7+)
$ ogrinfo --formats | grep GRASS
  -> "GRASS" (readonly)

you have to link these files from ../ into pkg/.

See
http://mpa.itc.it/markus/useful/conf_install_gdal_ogr_grass_plugin.sh
for a convenient script to compile/install - also the OGR plugin
in the same moment.

Personally, I no longer use the plugin extra package but
compile it directly from the standard GDAL code using my
script. That makes things even easier...

cheers

What README are you reffering to?

gdal-grass 1.3.1.2 README reads:

<quote>

./configure --with-gdal=/usr/local/bin/gdal-config
--with-grass=/usr/local/grass-6.0.0
make
sudo make install

</quote>

Following this procedure all works like a charm. Even I can skip
"--with-gdal=/usr/local/bin/gdal-config" as the plugin will find the
gdal-config itself for me.

make: *** No rule to make target `grass57dataset.o', needed by `gdal_GRASS.so'. Stop.

I never had this problem on Mandriva 2006, Ubuntu Breezy and now Dapper.

# ls /usr/local/lib/gdalplugins -l
lrwxrwxrwx 1 root staff 20 2005-10-24 16:17

# mkdir /usr/local/lib/gdalplugins

This step was never required for me to be able to install gdal-grass
plugin. I don't know what could be wrong in your case.

Maybe because I'm uisng checkinstall instead of make install, which
let's me maintain my custom software as packages, so I'm sure there no
leftovers from older/corrupted instalations.

Here's the most up to date debianized source, if you'd like to try it:
http://mentors.debian.net/debian/pool/main/c/checkinstall/

you have to link these files from ../ into pkg/.

Markus,

This is no longer required if using at least gdal-grass-1.3.1.1. Plain
configure, make, make install is enough now.

Personally, I no longer use the plugin extra package but
compile it directly from the standard GDAL code using my
script. That makes things even easier...

As to me, I prefer to maintain gdal-grass plugin as a separate deb
package so I can share it/install on other machines easily.
