[mapserver-dev] Revisit installing multiple mapserver versions

[Stephen Woodbridge]

Thomas,

I am have a problem with multiple mapserver versions installed. This is 
a common scenario in many environments. Looking at my system, I have:

> woodbri at mappy:$ ls /usr/local/lib/libmaps* -l
> -rwxr-xr-x 1 root root 5942968 2012-07-02 09:36 /usr/local/lib/libmapserver-6.1-dev.so
> -rwxr-xr-x 1 root root 5934502 2012-07-14 17:10 /usr/local/lib/libmapserver-6.2.0-beta1.so
> -rwxr-xr-x 1 root root 5935167 2012-07-14 23:24 /usr/local/lib/libmapserver-6.3-dev.so
> -rwxr-xr-x 1 root root    2066 2012-07-14 23:24 /usr/local/lib/libmapserver.la
> lrwxrwxrwx 1 root root      23 2012-07-14 23:24 /usr/local/lib/libmapserver.so -> libmapserver-6.3-dev.so
> woodbri at mappy:$ ls /usr/local/lib/libmapserver.so -l
> lrwxrwxrwx 1 root root 23 2012-07-14 23:24 /usr/local/lib/libmapserver.so -> libmapserver-6.3-dev.so

> woodbri at mappy:$ ls /usr/local/bin/mapserv
> /usr/local/bin/mapserv

> woodbri at mappy:$ mapserv -v
> MapServer version 6.3-dev OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ SUPPORTS=GD SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

This one works fine since it was last installed. But my typical pattern 
is to install mapserver then:

   cp /usr/local/bin/mapserv /path/to/cgi-bin/mapserv-<version>

So I have these on my system:

/usr/lib/cgi-bin/mapserv
/usr/lib/cgi-bin/mapserv-6.1-dev
/usr/lib/cgi-bin/mapserv-6.2-beta1
/usr/lib/cgi-bin/mapserv-60
/usr/lib/cgi-bin/mapserv-tc

I think the problem is the symlink:

/usr/local/lib/libmapserver.so -> libmapserver-6.3-dev.so

Ideally the executable should try to load the explicit library that it 
was built against and not some generic libmapserver.so that is a symlink 
and then I think everything would work just fine.

Is this something that can be done?

Thanks,
