[gecode-users] Compilation problem with GecodeJ 1.0.0 (debian linux)

[Zampelli Stephane]

Finally I managed to compile and run an example (thanks to Gregoire's help).

I had to use the following options for configure :

./configure
Gecode_CFLAGS="-I/home/szampelli/UCL/Recherche/Code/release-1.3.0/
-I/home/szampelli/UCL/Recherche/Code/release-1.3.0/gecode/"
Gecode_LIBS="-L/home/szampelli/UCL/Recherche/Code/release-1.3.0/
-lgecodesearch -lgecodeint -lgecodeset -lgecodekernel -lgecodeminimodel"

I has also to comment this depend in build.xml in order to get ant
running :

35 <!--    <depend srcdir="."
36            destdir="build"
37            cache="depcache"
38            closure="yes"
39            />-->

I set up CLASSPATH to point to GecodeJava.jar and build/ directory.

I set up LD_LIBRARY_PATH to point to gecode libraries.

I used the following line inside release-1.0.0 directory :
'/usr/local/jdk1.5.0_09/bin/java -Djava.library.path=. examples.Queens'.

The problem was that libgecodejava library was not pointing toward
gecode libraires, because the '-l' flags during linkage were missing. I
had to add them to Gecode_LIBS.

Hope this will help someone,

Stéphane.
