| + | ====== JPL ====== | ||
| + | [[http://www.swi-prolog.org/packages/jpl/|JPL]] is a library using the SWI-Prolog foreign interface and the Java jni interface providing a bidirectional interface between Java and Prolog that can be used to embed Prolog in Java as well as for embedding Java in Prolog. In both setups it provides a reentrant bidirectional interface. | ||

| + | ===== Installing SWI-Prolog with JPL in Linux ===== | ||
| + | |||
| + | Notice: Based on first-hand experience, the use of standard ''swi-prolog'' packages in Debian-based distributions is **not** recommended, due to the following: | ||
| + | * ''swi-prolog'' is absent in Debian Etch whatsoever (packages can be found in unstable and testing branches though), | ||
| + | * JPL is not included in Debian/Ubuntu packages (probably due to licensing issues, see below), | ||
| + | * the standard package name (''pl'') has been changed to ''swi-prolog''; that is known to break some things, including XPCE. | ||
| + | |||
| + | With the above in mind, the following options are available: | ||
| + | * use the stable RPM package available at the [[http://www.swi-prolog.org/dl-stable.html|SWI-Prolog download page]] (RPM-based distros only), | ||
| + | * install from source (coming soon), FIXME | ||
| + | * [[rpm2deb|convert the RPM package to DEB]] (in this case, rather harmless) or use the converted package, | ||
| + | * use binary packages compiled from the source (coming soon). FIXME | ||
| + | |||
| + | Alternatively, you can use the repository packages and install JPL as standalone. For now, posts #6 and #7 in [[http://ubuntuforums.org/showthread.php?t=447728|this discussion]] should provide some insight. | ||
| + | |||
| + | ===== Installing SWI-Prolog with JPL in Mac OS X ===== | ||
| + | |||
| + | Installation and testing instructions for Mac OS X can be found [[macosx|here]]. | ||
| + | |||
| + | ===== Dependencies ===== | ||
| + | |||
| + | DIYers should find [[dependencies|this]] handy. | ||
| + | |||
| + | |||
| + | ===== Testing ===== | ||
| + | |||
| + | The following can be used to test whether JPL is working properly: | ||
| + | |||
| + | * go to the ''lib'' directory of your JPL-enabled SWI-Prolog installation: | ||
| + | * if you're using Linux and installed the RPM package: ''/usr/lib/pl-<version>'' | ||
| + | * if you're a Mac user: ''/opt/local/lib/swipl-<version>'' | ||
| + | * cd to ''doc/packages/examples/jpl/java/Test'' | ||
| + | * delete ''Test.class'' to force re-compilation of the test app | ||
| + | * launch ''./run.sh'' | ||
| + | * if all goes well, you should get something like this: | ||
| + | |||
| + | bash-3.2# ./run.sh | ||

| + | ===== Packages ===== | ||
| + | |||
| + | The following SWI-Prolog with JPL packages are available: | ||
| + | |||
| + | * Debian/Ubuntu, converted from original RPMs: {{:prolog:jpl:pl_5.6.54-320_i386.deb|5.6.54}} | ||
| + | * OS X 10.4 and 10.5 users can get their installers [[http://www.swi-prolog.org/dl-stable.html|here]] | ||
| + | |||
| + | For DIY: | ||
| + | * //Patches vs. original debian/ubuntu packages// FIXME | ||
| + | * [[dependencies|build dependencies]] | ||
| + | |||
| + | |||
| + | |||
| + | ====== Specs ====== | ||
| + | Some insight plus specs: | ||
| + | * jpl is supposed to work with sun jdk only! (as stated by Jan W.) | ||
| + | * the main reason [[http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=449437|why jpl is not enabled]] in standard debian/ubuntu is the fact, that sun jdk is not free | ||
| + | * so compilation of jpl is disabled in debs by a debian patch, BUT removing the patch does not result in a working packages! why? | ||
| + | * we assume, that the packages built will use the standard sun-jdk packages, as generated by the [[http://packages.debian.org/etch/java-package|java-package for etch]] (and hardy) | ||
| + | * working with jdk 1.5 is a must! | ||
| + | * working with jdk 1.6 should also be tested and reported! use [[http://packages.debian.org/lenny/java-package|java-package from lenny]] | ||
| + | * it should be tested using current swi versions from both [[http://packages.debian.org/lenny/swi-prolog|testing]] and [[http://packages.debian.org/sid/swi-prolog|sid]]! | ||
| + | * check what changed (java package and swi vers) in intrepid ibex | ||
| + | * some main problems with jpl include a proper location and config. (paths, env vars) for //jpl.so// and //jpl.jar// | ||
| + | * I assume we get OS X instructions completely free too :-) | ||
| + | * in the future we might consider testing with openjdk, icedtea, classpath,gcj, whatever... but not now. | ||
