Hallo!

I build an application with the Mapserver 3.6. When I wanted to
try out raster reprojection I got the following error message:
"Raster reprojection supported only with the GDAL library.".

I build the binary with gdal, ogr and proj-support.
	./configure --with-proj --with-gdal --with-ogr 
Since I didn't find out any explanation I looked into the source 
code and found out, that raster reprojection is only possible when 
tiff-support is disabled, 
	./configure --with-proj --with-gdal --with-ogr --without-tiff	
since before the reprojection the mapserver checks
first, if gdal-support is enabled but also if tiff-support is
disabled:

---- in mapraster.c -------

#if !defined(USE_GDAL) || defined(USE_TIFF)
     if (memcmp(dd,"II*\0",4)==0 || memcmp(dd,"MM\0*",4)==0) {
       if(layer->transform &&
msProjectionsDiffer(&(map->projection), &(layer->projection))) {
         msSetError(MS_MISCERR, "Raster reprojection supported
only with the GDAL library.", "msDrawRasterLayer( TIFF )");

-----------------------------

So I suggest to change the first line to
#if !defined(USE_GDAL) 

I tried it out and it seems to work fine but perhaps I have
foreseen something (?).

Best regards

Silke
