项目需要,在python中调用java方法。于是乎在mac下安装jpype,网上有win32下的安装程序(.exe),没有直接的安装程序,需要编译源码安装。我下载的时是JPype-0.5.4.2,里面有如下文件:
这里的setup.py就是要运行的安装程序。
执行安装程序:python setup.py install。
报错:

看下setup.py,其中有个设置头文件的函数 :
在mac下,jni.h头文件的路径是:
/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers/
为了让安装程序能找到jni.h头文件,需要在这里加入jni.h的路径。修改setupInclsion(self)函数:
再次执行安装命令。
还报错:
/usr/bin/lipo: can't create output file: build/temp.macosx-10.8-intel-2.7/src/native/common/jp_array.o (Permission denied) clang: error: lipo command failed with exit code 1 (use -v to see invocation) error: command 'clang' failed with exit status 1
用root权限执行安装:sudo python setup.py install。
哦了!
