Question

我现在在Mac上安装了pljava。 pljava使用maven和maven nar插件进行构建。这个maven nar build目前正在创建一个dylib而不是.so。看起来postgres想要一个.so。这是转向postgres跟踪的输出：

所以我的问题是 - 如何让maven nar输出.so文件而不是.dylib？如果我使用“共享”类型，则会创建一个dylib，如果我使用“plugin”类型，则会创建.bundle，如果我使用“static”类型，则链接将失败。

我解决了我的问题。使用type＆＃34;插件＆＃34;创建正确类型的文件。迈尔斯对这个问题的回答帮助我弄明白了：

What are the differences between .so and .dylib on osx?

Mac OS建议.bundle扩展用于可加载模块，但移植的应用程序（如PostgreSQL）仍然希望使用.so。在我将文件名更改为pljava.so后，PostgreSQL成功加载了模块。

使用nar maven插件创建so而不是dylib
