g.gisenv: symbol lookup error: g.gisenv: undefined symbol: G__no_gisinit
The GRASS libraries are out of date with respect to the modules. The
libraries pre-date the version check, while the modules are more
recent.
I note that $LD_LIBRARY_PATH is rather long, and
/usr/local/grass-6.4.0svn/lib is right at the end of it:
If GRASS libraries exist in any other directory in $LD_LIBRARY_PATH
(or in /etc/ld.so.conf), they will be used in preference.
Also, it's possible that a different version of libgis is being pulled
in via e.g. GDAL.
I mentioned in my initial post to r-sig-geo, that I do have a grass63
installation on the same computer and that installation is from a Fedora
repository and comes as an rpm. I may have neglected to include that
information when I moved this thread to grass-stats. I likewise have two
installations of gdal (because the Fedora repository one is so old).
I had put /user/local/bin early in my PATH to try to avoid using the
older rpm versions, but I see now that, of course, the libraries from
the grass63 installation are probably being called first in this
instance. My user LD_LIBRARY_PATH env variable is empty and the library
path comes from ld.so.conf.
When initGRASS() gets the library path with Sys.getenv(), I'm not sure
how it comes up with the list of libraries that it does, but the
grass64svn library is not among them. initGRASS() appends the grass64svn
library to the end of the existing library path and sets it using
Sys.setenv().
I can try changing initGRASS to prepend the grass54svn library and see
if that works. But I am also wondering how I could change the order of
libraries in my library path from ld.so.conf.
I will try changing initGRASS() and report the results here.
Thanks for your help,
Bill
Ok, I have modified initGRASS() and named it myinitGRASS(). I have just
changed a couple of lines to prepend the grass64svn directories, rather
than append them, to PATH and LD_LIBRARY_PATH. These appears to work
fine, but I don't know what other ramifications it might have:
