JPype编译问题 [英] JPype compile problems

问题描述

我和JPype有一个正确的老噩梦。我在Windows上有我的开发环境，因此尝试在那里安装它没有运气。然后我尝试了Ubunto也没有运气。我现在有点绝望了。我使用Mingw32，因为我尝试安装VS2008，但它告诉我我必须安装XP SP2，但我在Vista上。我试过VS2010，但没有运气，我得到'错误：无法找到vcvarsall.bat'错误。无论如何，我现在在Mingw32

I'm having a right old nightmare with JPype. I have got my dev env on Windows and so tried installing it there with no luck. I then tried on Ubunto also with no luck. I'm getting a bit desperate now. I am using Mingw32 since I tried installing VS2008 but it told me I had to install XP SP2 but I am on Vista. I tried VS2010 but no luck, I got the 'error: Unable to find vcvarsall.bat' error. Anyway, I am now on Mingw32

最终我试图使用Neo4j和Python因此我需要使用JPype。我在网上找到了很多关于MySQL等问题的引用，但它们对我没有帮助。

Ultimately I am trying to use Neo4j and Python hence my need to use JPype. I have found so many references to the problem on the net for MySQL etc but they don't help me with JPype.

如果我可以修复unix或windows，我可以开始这样的帮助，将非常感谢。

If I could fix unix or windows I could get going so help on either will be really appreciated.

这是版本..

Windows：Vista 64
Python：2.6
编译器Mingw32：最新版本
Jpype：0.5.4.1
Java信息：
java版本1.6.0_13
Java（TM）SE运行时环境（版本1.6.0_13-b03 ）
Java HotSpot（TM）64位服务器VM（版本11.3-b02，混合模式）

Windows: Vista 64 Python: 2.6 Compiler Mingw32: latest version Jpype: 0.5.4.1 Java info: java version "1.6.0_13" Java(TM) SE Runtime Environment (build 1.6.0_13-b03) Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02, mixed mode)

我运行：

python setup.py install --compiler = wingw32

python setup.py install --compiler=wingw32

并获得以下输出。

选择Windows配置文件
运行安装
运行build
运行build_py
运行build_ext
构建'_jpype'扩展名

所以在unix Ubunto上问题如下：

So on unix Ubunto the problem is as follows:

Java版本：1.6.0_18
JPype：0.5.4.1
Python：2.6

Java version: 1.6.0_18 JPype: 0.5.4.1 Python: 2.6

Java在路径中，我做了apt-get install build - 刚才有最新的GCC等。

Java is in the path and I did apt-get install build-essentials just now so have latest GCC etc.

我不会粘贴所有输出，因为它很大。这么多的错误就像我错过了Java或类似的安装，但我没有。输入java将我带入上面的版本。这是开始：

I won't paste all the output as it's massive. So many errors it's like I have missed the install of Java or similar but I haven't. typing java takes me into version above. This is the beginning:

推荐答案

我在Linux上遇到了同样的错误。它对我来说只是执行

I had the same error on Linux. It worked for me just executing

export JAVA_HOME=/usr/lib/[*your_java_folder*]

查看setup.py第45行：

Look at setup.py line 45:

def setupLinux(self):        
self.javaHome = os.getenv("JAVA_HOME")
if self.javaHome is None :
    self.javaHome = '/usr/lib/jvm/java-1.5.0-sun-1.5.0.08' # Ubuntu linux
