G ++找不到Boost库。我说，他们在众目睽睽 [英] G++ can't find boost libraries. I say they're in plain sight

问题描述

我试图建立一些code。下面是我得到的错误：

I'm trying to build some code. Here is the error I'm getting:

main.o: In function `__static_initialization_and_destruction_0':
/home/jmbeck/Downloads/boost_1_48_0/boost/system/error_code.hpp:214: undefined reference to `boost::system::generic_category()'

还有更多，但我不认为这是相关的。

There is more, but I don't think it's relevant.

下面是构建命令：

g++ -I/home/jmbeck/Downloads/boost_1_48_0 
    -L/home/jmbeck/Downloads/boost_1_48_0/stage/lib 
    -lm 
    -lboost_system 
    -lboost_thread
    -lboost_regex 
    main.cpp

到/ home / jmbeck /下载/ boost_1_48_0 /舞台/ lib目录中包含预期的文件：

The /home/jmbeck/Downloads/boost_1_48_0/stage/lib directory contains the expected files:

libboost_system.a
libboost_system.so@
libboost_system.so.1.48.0*
libboost_thread.a
libboost_thread.so@
libboost_thread.so.1.48.0* 
libboost_regex.a
libboost_regex.so@
libboost_regex.so.1.48.0*
... etc...

我试图建立一个快速的程序，没有使用pre-编译库，它编译就好了。它找到合适的标题，而不是库。

I've tried building a quick program that didn't use the pre-compiled libraries, and it compiled just fine. It finds the appropriate headers, but not the libraries.

我在做什么错了？

推荐答案

尝试把库中的之后的的main.cpp 。

我已经经历了过去的一些怪事，当GCC忽略库，因为它不认为他们已经习惯，达到我的源文件了。

I've experienced some weirdness in the past when GCC ignores libraries because it doesn't think they're used, before reaching my source files.
