我目前正在尝试创建Java Freeling API，以便在Stanbol上使用它。
这样，我没有遵循Freeling文档（此处为https://github.com/insideout10/stanbol-freeling）给出的所有说明。我的JDK似乎有问题，但我真的不知道如何解决。
这就是我所做的：
步骤A，用C ++编译Freeling（这里没有问题）：
A.1）安装以下软件包（使用“ sudo apt-get install”）：
-必要的
-zlib1g-dev
-libboost1.48-all-dev
-自动制作
-自动配置
-libtool
-libboost-regex-dev
-libicu-dev
-libboost-filesystem-dev
-libboost-program-options-dev
-痛饮
A.2）下载最新版本的冻结：
svn checkout http://devel.cpl.upc.edu/freeling/svn/trunk冻结
A.3）准备我的Freeling存储库：
本地libtoolize; autoconf;自动制作-a
4）构建并安装Freeling：
。/配置
使
须藤使安装
步骤B，编译Java API（我的问题是在此步骤中）：
1）将freeling.i替换为freeling.i，位于以下位置：[url] https://raw.github.com/ziodave/freeling-brew-formula/master/APIs /common/freeling.i[/url]
2）将Makefile的参数设置为freeling / APIs / java / MakeFile
我的Makefile如下：
# 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）运行make
我得到以下结果：
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

make: *** [libfreeling_javaAPI.so] Error 1
据我了解，Makefile只是调用JDK并遇到错误。
我尝试将JDK更改为旧版本（尝试使用JDK7，JDK6和SDK6），但结果是相同的。
有关信息，我在使用Ubuntu12.04 x64的虚拟机中工作，我还尝试使用Ubuntu12.04 x32编译Freeling，但结果是相同的。
我在.bashrc上添加了以下几行：
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
我认为我做错了事，但我真的不知道该怎么办，我花了3天的时间才找到解决方案，但没有成功。有人可以帮我吗？
先感谢您 ！
最佳答案
因此，看来您比我优越得多，但是我注意到您设置了环境变量的路径，您是否还检查以确保系统将哪个版本的Java用作默认总体？
尝试使用
sudo update-alternatives --config java
并确保使用正确的JDK。
如果您已经解决了此问题，则很想听听您的解决方案（因为您之前发布了此信息）。
