Hi all,I'm having issues trying to compile GDAL with MrSID support.

A preliminary question I have is: is MrSID write support available in GDAL, 
provided one has LizardTech's encoding SDK (ESDK)?
The documentation is a bit confusing on this point, e.g. on this page 
http://www.gdal.org/formats_list.html MrSID creation support is denied, whereas 
on this page https://trac.osgeo.org/gdal/wiki/MrSID it is stated that it 
requires an ESDK.


I have two versions of the MrSID SDK from LizardTech, Geo_ESDK-7.0.0.2167 (both 
encoding and decoding) and MrSID_DSDK-9.1.0.4045 (decoding only).
The platform I'm building on is:
CentOS 5.11 64-bit
gcc 4.1.2 20080704 (Red Hat 4.1.2-55)


I tried several versions of GDAL, 1.7.1, 1.7.3, 1.9.2, 2.0.0 but I keep getting 
the same error, when linking to Geo_ESDK-7.0.0.2167:

I tried both --with-libtool and --without-libtool options and I get the same 
error. Looks like libltidsdk.so contains undefined references to functions... 
which should be defined in the library itself?


If I try to link to MrSID_DSDK-9.1.0.4045 (gcc41 version), I get a different 
error on GDAL 1.7.1 through 1.9.2:
/bin/sh /root/gdal/gdal-1.9.2/libtool --mode=link       g++  gdalinfo.lo  
/root/gdal/gdal-1.9.2/libgdal.la -o gdalinfo
libtool: link: g++ .libs/gdalinfo.o -o .libs/gdalinfo

/root/gdal/gdal-1.9.2/.libs/libgdal.so: undefined reference to 
`LizardTech::LTISceneBuffer::LTISceneBuffer(LizardTech::LTIPixel const&,

/root/gdal/gdal-1.9.2/.libs/libgdal.so: undefined reference to 
`LizardTech::J2KImageReader::initialize(LizardTech::LTIOStreamInf&, bool, 
float, bool, int)'


The only successful combination I found so far has been GDAL 2.0.0 and 
MrSID_DSDK-9.1.0.4045: it's something, but I'd very much prefer to link with 
Geo_ESDK-7.0.0.2167 to have read / write support.




Has anybody experienced the same issues?
