tring to rebuild the gdal-grass plugin on my linux (debian sid)
but i'm having this error

epifanio@epybox:/etc/ld.so.conf.d$ cat grass.conf
#/usr/local/grass-7.0.svn/lib
/usr/local/grass-6.5.svn/lib

include /usr/local/grass-6.5.svn/lib?

have you any clue ? the error happens if i try to build the gdal-grass
plugin using grass 6.5 ... instead using the 7.0 it build fine.

the config.log file contents : http://paste.debian.net/112667/
it can't find lib .. but they exists

thanks for any hints!

Massimo.

The 6.x build system no longer generates the unversioned symlinks,
which the configure script requires.

This has long been the case for the 7.0 build system, but the
gdal-grass configure script explicitly checks for the versioned names
for 7.0.

You could just generate the symlinks yourself, e.g.:

  cd /usr/local/grass-6.5.svn/lib
  for file in libgrass_*.so ; do ln -s $file ${file%.6.5.svn.so}.so ; done
