I believe these are all references to the same problem.  If you =
recompiled MapServer and got the same result, then you are still =
building with two different JPEG libraries in there somewhere.

Check your MapServer makefile for references to the jpeg-6b library, and =
check all the makefiles for supporting libraries, as well.  Be sure you =
are linking against GDAL.LIB rather than a custom JPEG library created =
in the frmts\jpeg directory.

I have attached my GD-2.0.11 Windows VC++ makefile for your reference.

No, that didn't work either. I created a library in=20
gdal-1.1.8\frmts\jpeg (lib out:libjpeg.lib *.obj) and linked GD 2.0.11=20
against this library, instead of the original libjpeg.lib. Then I=20
recompiled MapServer, and got the same result.

Norman Vine pointed me to a recent posting by Daniel Morissette on this=20
problem,

http://lists.gis.umn.edu/pipermail/mapserver-users/2003-January/000657.ht=
ml

and a bugzilla item in

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=3D203

The problem is more difficult than stated there: recompiling MapServer=20
without -DUSE_JPEG didn't help. Neither did compiling GD with the JPEG=20
routines from GDAL. Finally, it is NOT a Windows problem: Apache on=20
Linux came with the same error, although with a different size (464=20
instead of 520)

 >> JPEG parameter struct mismatch: library thinks size is 464, caller
 >> expects 464

As a last resort I completely removed GDAL from the build and tried to=20
display the jpeg image. This time I got the error message:

 >> msDrawRasterLayer(): General error message. Attempt to render raster
 >> layer to IMAGEMODE RGB or RGBA but without GDAL available. 24bit
 >> output requires GDAL

I'm out of my depth.

>>Please forgive my incomplete recollection, but I ran into this same =
problem a long time ago.  It appears that the JPEG library inside GDAL =
is built slightly differently than the default jpeg-6b library (although =
it's the same version), and the two are not compatible.  I suspected it =
was a structure packing/alignment issue (i.e. the files are the same but =
they're compiled differently).  I decided not to look into it and simply =
use the JPEG support from GDAL and remove the jpeg-6b library from my =
build.  That fixed the problem.
