我目前正在尝试为 Freeling 创建 Java API，以便在 Stanbol 上使用它。这样，我遵循了 Freeling 文档（此处：https ://github.com/insideout10/stanbol-freeling ）给出的所有说明，但没有成功。这似乎是我的 JDK 的问题，但我真的不知道如何解决它。这就是我所做的：

步骤A，用C++编译Freeling（这里没问题）：

A.1 ) 安装以下软件包（使用“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 ) 下载最新版本的Freeling：svn checkout http://devel.cpl.upc.edu/freeling/svn/trunk Freeling

A.3 ) 准备我的 Freeling 存储库：aclocal；库工具化；自动配置；自动制作 -a

4 ) 构建和安装 Freeling: ./configure make sudo make install

步骤B，编译Java API（我的问题在这一步）：

1 ) 用 freeling.i 替换位于 freeling/APIs/common/freeling.i 的 freeling.i：[url]https://raw.github.com/ziodave/freeling-brew-formula/master/APIs /common/freeling.i[/url]

2 ) 设置位于 freeling/APIs/java/MakeFile 的 Makefile 的参数

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）运行制作

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

如果我理解，Makefile 只是调用 JDK 并遇到错误。

我尝试使用旧版本更改我的 JDK（我尝试使用 JDK7、JDK6 和 SDK6），但结果是一样的。

有关我正在使用 Ubuntu12.04 x64 的虚拟机中工作的信息，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

我认为我做错了什么，但我真的不知道是什么，我花了 3 天时间才找到解决方案，但没有成功。有人可以帮助我吗？

先感谢您 ！

所以看起来你比我优越得多，但我注意到你设置了环境变量的路径，你是否也检查过你的系统使用哪个版本的 java 作为默认的整体？

尝试使用

sudo update-alternatives --config java

并确保使用了正确的 JDK。

如果您已经解决了这个问题，我很想听听您的解决方案（因为您刚刚发布了此问题）。
