用nginx-gridfs编译nginx，在make过程中获取mongo-c-驱动程序错误。

Question

我试图在Ubuntu 11.10 (gcc版本4.6)上使用nginx模块编译具有gridfs支持的nginx (版本1.0.11) (nginx版本0.8)：

https://github.com/mdirolf/nginx-gridfs

这里描述的安装说明很简单：

* Clone the nginx-gridfs repository (`git clone https://github.com/mdirolf/nginx-gridfs`)
* Check out the mongo-c-driver submodule (`git submodule init` then `git submodule update`)
* Download and unpack the nginx source (from `http://nginx.org/download/nginx-1.0.11.tar.gz`)
* Run `./configure` with `--add-module=/path/to/nginx-gridfs/repository`
* `make` and `sudo make install`

上一次我在一台机器上安装nginx-gridfs (大约四个月前在Ubuntu10.04上，gcc 4.5和nginx版本1.0.5)，这些步骤对我来说很好，但是现在(在一个新的Ubuntu安装上)我得到了一个错误。./configure运行良好，但make在以下方面失败：

cc1: all warnings being treated as errors
make[1]: *** [objs/addon/src/mongo.o] Error 1

知道为什么会失败吗？

cc1: all warnings being treated as errors使我相信，我可以将-Wno-error添加到CFLAGS中，告诉它不要将警告视为错误，以避免此问题。但我担心，在这里启用警告作为错误是有原因的，关闭它只会使编译在表面上成功，但实际上行不通。

有人知道这是怎么回事吗？

Answer 1

使用忽略警告方法可以完成编译工作，但实际上，如果使用用户/密码错误，则无法连接到数据库。对我起作用的是从零开始构建mongo到用更新的lib提供nginx构建的组合：http://pastebin.com/tMsL2eC9。

但这还不够。我还必须特别检查nginx子模块中的mongo驱动程序v0.3.1。也就是说，nginx网格资源的v0.8。V0.3.1 mongo c驱动程序，而新的mongo构建是来自该链接中指定的env的引用。然后，我构建了nginx1.0.11，没有任何错误，而且成功了。
