[Gdal-dev] MrSID ESDK problems

[Sheykhet, Rostic]

Dion,

I think that depending on the LizardTech license, you need to set 
LT_UMDB_PATH variable to point to the directory like
/usr/local/LizardTech/ECM/db in order to write MrSID files.

Hello Frank,

As I'm working with Bart on the same project, let me provide the
information
you asked for.

ESDK-5.0.6.955

Yes. In fact, here's the complete output:

Format Details:
  Short Name: MrSID
  Long Name: Multi-resolution Seamless Image Database (MrSID)
  Extension: sid
  Help Topic: frmt_mrsid.html
  Supports: CreateCopy() - Create dataset by copying another.
  Creation Datatypes: Byte Int16 UInt16 Int32 UInt32 Float32 Float64

<CreationOptionList>
  <Option name="COMPRESSION" type="double" description="Set compression
ratio (0.0 default is meant to be less)"/>
  <Option name="TWOPASS" type="int" description="Use twopass optimizer
algorithm"/>
  <Option name="FILESIZE" type="int" description="Set target file size
(0
implies lossless compression)"/
  <Option name="WORLDFILE" type="boolean" description="Write out world
file"/>
  <Option name="VERSION" type="int" description="Valid versions are 2
and
3, default = 3"/>
</CreationOptionList>

We are building on Linux (Redhat ES 3.0). I think the -DMRSID_ESDK
is used when building. 'config.log' contains the following:

....
configure:25219: checking for lt_base.h in
/opt/Geo_ESDK-5.0.6.955/include/support
configure:25222: result: found MrSID DSDK version 4.x or newer.
configure:25229: checking for MG3ImageWriter.h in
/opt/Geo_ESDK-5.0.6.955/include/mrsid_writers
configure:25232: result: found MrSID ESDK version 4.x or newer.
configure:25239: checking for MrSID JPEG2000 support

-I/opt/Geo_ESDK-5.0.6.955/include/support'

Also, a 'make' in frmts/mrsid shows the following:

/bin/sh ../../libtool --mode=compile g++ -Wall  -O2 -march=i386
-mcpu=i686
  -I../../port -I../../gcore -I..  /../alg -I../../ogr

-D_REENTRANT  -I../../port -I/us  r/local/include  -c -o mrsiddataset.o
mrsiddataset.cpp

A problem that is probably related is that mapserver 4.8.0-rc2 also
fails to write MrSID output when doing a WCS GetCoverage request. It
throws an ServiceException:
msSaveImageGDAL(): General error message. Failed to create output MrSID
file.
`/data/OGC_UMN_services/tmp/ms_tmp/1136930007234670.sid&#39; not
recognised as a supported file format.

Dion
