Freeling : Unable to compile the Java API on Ubuntu

Question

I'm currently trying to create the Java API for Freeling in order to use it on Stanbol. In this way, I followed all the instructions given by the Freeling documentation (here :https://github.com/insideout10/stanbol-freeling) without success. It seems to be a problem with my JDK but I really don't know how to fix it. This is what I've done :

Step A, compile Freeling in C++ (no problem here):

A.1) Install the following packages (with "sudo apt-get install") : - build-essential - zlib1g-dev - libboost1.48-all-dev - automake - autoconf - libtool - libboost-regex-dev - libicu-dev - libboost-filesystem-dev - libboost-program-options-dev - swig

A.2) Download the latest version of Freeling: svn checkout http://devel.cpl.upc.edu/freeling/svn/trunk Freeling

A.3) Prepare my Freeling repository: aclocal; libtoolize; autoconf; automake -a

4) Build and install Freeling: ./configure make sudo make install

Step B, compile the Java API (my problem is in this step):

1) Replace the freeling.i located to freeling/APIs/common/freeling.i by the freeling.i given at : [url]https://raw.github.com/ziodave/freeling-brew-formula/master/APIs/common/freeling.i[/url]

2) Set the parameters for the Makefile located to freeling/APIs/java/MakeFile

My Makefile is the following :

# Change these paths to match your installation
# Alternatively, you can call 'make' overriding variable values, E.g.:
#     make FREELINGDIR=/my/freeling/dir SWIGDIR=/my/swig/dir JAVADIR=/my/java/dir

FREELINGDIR = /home/saturn/freeling
SWIGDIR = /usr/share/swig2.0
JAVADIR = /usr/lib/jvm/jdk1.7.0_25

# you may change the package name if you want
PACKAGE = edu/upc/freeling
JPACKAGE = edu.upc.freeling

# Change your compiler, if necessary.
GCC=g++

all: freeling_javaAPI.cxx libfreeling_javaAPI.so

.PHONY: all

# Compile the C++ API
libfreeling_javaAPI.so: freeling_javaAPI.cxx
    $(GCC) -shared -o libfreeling_javaAPI.so freeling_javaAPI.cxx -lfreeling -L$(FREELINGDIR)/lib -I$(FREELINGDIR)/include -I$(JAVADIR)/include -I$(JAVADIR)/include/linux -fPIC
    $(JAVADIR)/bin/javac $(PACKAGE)/*.java
    $(JAVADIR)/bin/jar -cf freeling.jar $(PACKAGE)

# Build the Java JNI wrapper classes.
freeling_javaAPI.cxx: freeling_javaAPI.i ../common/freeling.i
    rm -rf $(PACKAGE)
    mkdir -p $(PACKAGE)
    swig -java -c++ -package $(JPACKAGE) -outdir $(PACKAGE) -o freeling_javaAPI.cxx -I$(SWIGDIR)/java -I$(SWIGDIR)/std -I$(SWIGDIR) freeling_javaAPI.i

clean:
    rm -rf *.jar *.so *.cxx *.class edu
    java -> $(JAVADIR)/bin/java
    jar -> $(JAVADIR)/bin/jar

3) Run make

And I get the following result :

g++ -shared -o libfreeling_javaAPI.so freeling_javaAPI.cxx -lfreeling -L/usr/local/share/freeling/lib -I/usr/local/share/freeling/include -I/usr/lib/jvm/jdk1.7.0_25/include -I/usr/lib/jvm/jdk1.7.0_25/include/linux -fPIC

If I understand, the Makefile just call the JDK and encounter error.

I tried to change my JDK with older versions (I tried with JDK7, JDK6 and SDK6) but the result is the same.

For information I'm working in a virtual machine with Ubuntu12.04 x64, I also tried to compile Freeling with Ubuntu12.04 x32 but the result is the same.

I added the following lines on my .bashrc :

JAVA_HOME=/usr/lib/jvm/jdk1.7.0_25
MAVEN_OPTS="-Xmx2048m -XX:MaxPermSize=2048m"
JAVA_OPTS="-Xmx2048m -XX:MaxPermSize=2048m"
ANT_OPTS="-Xmx2048m -XX:MaxPermSize=2048m"
JVM_ARGS="-Xmx2048m -XX:MaxPermSize=2048m"
export MAVEN_OPTS
export JAVA_OPTS
export ANT_OPTS
export JVM_ARGS
export JAVA_HOME

I think I'm doing something wrong but I really don't know what, I spent 3 days to find a solution without success. Could someone help me ?

Thank you in advance !

So it appears that you are far superior than me, but I noticed that you set-up your environmental variable's path, did you also check to make sure which version of java your system is using as the default overall?

Try using

sudo update-alternatives --config java

and making sure the right JDK is being used.

If you already solved this issue, I'd love to hear your solution (since you posted this awhile ago).
