lib-gd strange error

[Alessandro Pasotti]

Hi,

I have a really strange error on a 64 bit linux where I have installed both 
php_mapscript and mapserv 4.10.1 plus shp2img &C..

The error from shp2img is the following:

# shp2img -l News -m /srv/www/htdocs_ssl/maps/mapfile.map -all_debug 9 
> /dev/null
gd-png:  fatal libpng error: Invalid image width
gd-png error: setjmp returns error condition
msLoadMap(): General error message. Undefined overlay 
symbol "/srv/www/htdocs/images/stories/con_info.png" in class 0, style 0 of 
layer News. <br>
msAddImageSymbol(): GD library error.  <br>

******* See:
https://85.18.34.128/cgi-bin/mapserv?map=/srv/www/htdocs_ssl/maps/mapfile.map&mode=map&layer=News

Now, if I draw this layer in the php_mapscript generated webgis (that reads 
the same mapfile), all is ok, and I can see the icon 
(/srv/www/htdocs/images/stories/con_info.png) on the map for that layer.

******* See:
http://85.18.34.128/vnlib/pmapper-dev/map.phtml?dg=News&me=1510570.0418719,5038600,1520156.9581281,5044582&language=it


I carefully checked permissions, paths etc.

"ldd" output for all the libraries and binaries involved shows that all are 
using the same library: 
# ldd mapserv|grep gd
        libgd.so.2 => /usr/lib64/libgd.so.2 (0x00002aaaaabc2000)

# ldd php_mapscript.so|grep gd
        libgd.so.2 => /usr/lib64/libgd.so.2 (0x00002aaaac29e000)


I really cannot understand what is happening here, and how to try debugging 
this.

/srv/www/cgi-bin/mapserv -v
MapServer version 4.10.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP 
OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER 
SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT INPUT=EPPL7 
INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE


Any help would be highly appreciated.

Thanks.
