[mapserver-users] 24bit tiff and gdal

[Pushkar Pradhan]

Frank,
Thanks for confirming my doubt about disabling TIFF support:
so now my MS config. says:
Banshee[51] pushkar$ mapserv -v
MapServer version 3.5 OUTPUT=PNG OUTPUT=WBMP SUPPORTS=TTF INPUT=EPPL7
INPUT=JPEG INPUT=GDAL INPUT=SHAPEFILE
But to my horror now I am unable to read either 8 or 24 bit TIFFs, I get
the foll. error:
msDrawRaster(): Image handling error. Unrecognized or unsupported image
format
and when I try to display colored jpegs also it doesn't work:
drawJPEG(): Unable to access file. Only grayscale JPEG images are
supported.
This is my path:
Banshee[91] pushkar$  echo $LD_LIBRARY_PATH
/usr/lib:/usr/local/lib:/usr/dt/lib:/usr/openwin/lib:/usr/local/gnu/lib:/opt/SUNWspro/lib:/usr/ccs/lib:/usr/ucblib:/usr/local/netpbm/lib:/rstc/user1/erc/pushkar/gdal-1.1.5
i.e. I have given the path to the gdal dir.
Apache's error log says:
[Fri Feb  8 15:01:51 2002] [notice] SIGUSR1 received.  Doing graceful
restart
[Fri Feb  8 15:01:51 2002] [notice] Apache/1.3.22 (Unix) configured --

Am I not linking properly or something?
