[Mapserver-users] rojection library error. no system list, errno: 2

Thu May 8 12:33:59 EDT 2003

Hi Frank,

thanks to you. Sorry for that long mail again, I am still stuck and could
not find any more helpful information in the mailing list archives or at
MapServerWiki.

shp2img responds the same error message!!

----------------------------------------------------------------------------
--------------------
root at qwertzuiop# /usr/home/src/mapserver-3.6.5/shp2img -m
/usr/home/umn/test1.map -o /tmp/test
pj_open_lib(proj_def.dat): call fopen(/usr/local/share/proj/proj_def.dat).
pj_open_lib(EPSG): call fopen(/usr/local/share/proj/EPSG).
msProcessProjection(): Projection library error. no system list, errno: 2
----------------------------------------------------------------------------
--------------------

Is this maybe a hint? Why does proj -v find the epsg file (see below) and
shp2img not?

Why is shp2img not installed in /usr/local/bin/ like "shp2pgsql"? Is that
ok?

I then checked all permissions. Everybody has read permissions on
/usr/local/share/proj/epsg, as you can see below in the directory listing.

benjamin at qwertzuiop> cd /usr/local/share/proj/
benjamin at qwertzuiop> l epsg
-r--r--r--  1 root  wheel  196424 Mar 25 18:24 epsg

Apache runs as user www (or nobody on Linux), so I suppose cgi-processes are
run with the same user...?!

I have my umn data in /usr/home/umn:
data/test/ --> SHAPEPATH
sessions/ --> IMAGEPATH
symbols/
test1.map

I checked permissions within /usr/home/umn. At least everyone has r--. Maybe
that is not enough. But I don't think so, because, why should rwx be
neccessary.
At last I've downloaded the latest epsg-file, changed the owner from root to
an ordinary user and made chmod 777. Changing user and permissions does't
help at all.

Then I found out the following strange thing:

root at qwertzuiop# proj -v +init=epsg:31493
pj_open_lib(epsg): call fopen(/usr/local/share/proj/epsg).
Rel. 4.4.5, 9 January 2002
<proj>:
projection initialization failure
cause: no options found in 'init' file
program abnormally terminated

root at qwertzuiop# proj -v +init=epsg:4326
pj_open_lib(epsg): call fopen(/usr/local/share/proj/epsg).
Rel. 4.4.5, 9 January 2002
<proj>:
+proj=latlong unsuitable for use with proj program.
program abnormally terminated

Then I found out that there are no entries for epsg:3149X in the new
epsg-file!!?? So I took the old epsg-file. There are epsg:3149X entries in
it. proj -v +init=epsg:4326 responds the same.

Do you have an another idea what's that "no system list"-thing is?

Thanks in advance,
Benjamin

Maybe it provides some helpful information, here is my map-file:
