JP2KAK is the Kakadu based GDAL Driver for JPEG2000 image data. There are several other JPEG2000 drivers as well (JPEG200 - JasPer, JP2MRSID - MrSID SDK, JP2ECW - ECW SDK). The Kakadu library is proprietary, but can be licensed under reasonable terms for various uses. Unfortunately it comes with a slightly unusual build system which makes it hard to build against.
Building Kakadu on Unix/Linux
The following guide walks through steps required to build Kakadu 6.0 and GDAL with JP2KAK driver support on 32-bit Linux machine. Instructions presented here have been tested under Ubuntu Linux.
- Prerequisites
You have obtained Kakadu source code and license in version 6.0.
- Unpack Kakadu 6.0 sources to preferred location
$ cp v6_0-00256n.zip /usr/local $ cd /usr/local $ unzip v6_0-00256n.zip $ mv v6_0-00256N kakadu-6.0
Note: I assume you have sufficient privileges to operate in /usr/local directory or you have chosen different location.
The location /usr/local/kakadu-6.0 will be used as building workspace and also as installation directory, because there is no make install step when building Kakadu.
$ cd /usr/local/kakadu-6.0
- Build subtree coresys
$ cd coresys/make $ make -f Makefile-Linux-x86-32-gcc $ cd ../..
- Build subtree apps
cd apps/make $ make -f Makefile-Linux-x86-32-gcc $ cd ../..
- Copy libraries to location where GDAL expects to find them
$ pwd /usr/local/kakadu-6.0 $ mv lib/Linux-x86-32-gcc/* lib/
After this step, Kakadu libraries can be found here:
$ cd /usr/local/kakadu-6.0/lib $ ls lib* libkdu.a libkdu_stacksafe32.a libkdu_v60R.so
Building GDAL with Kakadu support
- Configuration
$ ./configure --with-kakadu=/usr/local/kakadu-6.0
As you see, --with-kakadu option takes root (prefix) of Kakadu installation directory. As mentioned in the previous section, GDAL building scripts will look for Kakadu binaries in subdirectory /usr/local/kakadu-6.0/lib.
Verify if ./configure successfully detected Kakadu files:
... GDAL is now configured for i686-pc-linux-gnu Installation directory: /home/mloskot/usr C compiler: gcc -O2 C++ compiler: g++ -O2 LIBTOOL support: no ... KAKADU support: yes ...
- Build GDAL with JP2KAK driver
$ make
Unix/Linux Builds by Frank
This is how I setup to use Kakadu 6.0 on my 64bit linux system with GDAL 1.4.x. Other makefiles exist for 32bit linux and a few other variations. You may have to fiddle with the makefiles some if your environment is odd.
(this is in progress - my build with v6 isn't actually working yet)
unzip v6_0-00256n.zip mv v6_0-00256N kakadu-6.0 cd kakadu-6.0/coresys/make make -f Makefile-Linux-x86-64-gcc cd ../../ cp lib/Linux-x86-64-gcc/* /usr/local/lib cd apps/make
Edit to add -fPIC in compile options.
make -f Makefile-Linux-x86-64-gcc
Then I configure GDAL like this:
./configure --with-kakadu=/home/warmerda/pkg/kakadu-6.0
and build. The Kakadu libraries are used as static libraries, so there are no .so's to carry along.
