Hi,
I do'nt know if this is more an issue for DebianGIS, but I have the
feeling it is an upstream issue, so I'm posting it here. Please redirect
me if you think I'm wrong.
I'm trying to activate MrSID support for GDAL.
I downloaded and unpacked MrSID_DSDK-9.1.0.4045-linux.x86-64.gcc44.
Then I ran the following on a Debian testing machine:
**
apt-get source gdal
cd gdal-1.10.1+dfsg/
debian/rules gdal-mrsid (which AFAIU basically just creates
libgdal-mrsid-1.10.1.tar.gz and copies it to the directory above the
GDAL source directory)
cd ../
tar xvzf libgdal-mrsid-1.10.1.tar.gz
cd libgdal-mrsid-1.10.1/
chmod +x configure
./configure --with-gdal=/usr/bin/gdal-config
--with-mrsid=/home/mlennert/SRC/MrSID_DSDK-9.1.0.4045-linux.x86-64.gcc44/Raster_DSDK
--with-jp2mrsid=no
make
sudo make install
**
I do not get any error message, but when I run
gdalinfo --formats | grep -i sid
the MrSID format is not listed.
I ran ldd on the plugin .so installed in /usr/lib/gdalplugin
and saw that it couldn't find libltidsdk.so.
So I set
export
LD_LIBRARY_PATH=/home/mlennert/SRC/MrSID_DSDK-9.1.0.4045-linux.x86-64.gcc44/Raster_DSDK/lib/
and now ldd could find the library, but MrSID is still not listed
amongst the available formats.
I don't know if I completely misunderstand how this should be done, or
if this a bug of some sorts.
Several questions are open for me:
- Seeing that the SDK seems to have been compiled with gcc44 do I have
to use that too ? And does that mean I have to use gcc44 to compile gdal
and all its dependencies manually ?
- The SDK contains libgeos.so files but in a version that seems older
than the one in Debian Jessie. Could that be a source of conflict that
keeps GDAL from recognizing the plugin ?
Any hints and pointers would be appreciated.
Thanks !
Moritz
As I travel down the compile path, I always make sure to follow and
edit/update the BuildHints[1] wiki page for GDAL. On that page MrSID
instructions are also listed[2]. For example, for building on Windows I
always must point to both the RASTER and LIDAR sdk's for this to work
properly (the equivalent on unix would be --with-mrsid and
--with-mrsid_lidar)
It would be great if you could update this buildhints page with your own
hints/advice for others too, during your travels.
