doesn't compile if included boost/thread in linux Ubuntu:)10.10
提问by andrissh
I work in eclipse under linux UBUNTU:) 10.10, installed the boost-dev packages 1.40 using the Synaptic pkg manager. I am new to linux and this boost pkg. I try to create a new project, and write:
我在 linux UBUNTU 下的 eclipse 中工作 :) 10.10，使用 Synaptic pkg 管理器安装了 boost-dev 包 1.40。我是 linux 的新手，这个 boost pkg。我尝试创建一个新项目，然后写：
#include <boost/thread.hpp>
int main(int argc, char* argv[]){
}
I did not include anything or write anything like pthread anywhere. when trying to build, it says:
我没有在任何地方包含任何东西或写任何类似 pthread 的东西。尝试构建时，它说：
/usr/include/boost/config/requires_threads.hpp:47: error: #error "Compiler threading support is not turned on. Please set the correct command line options for threading: -pthread (Linux), -pthreads (Solaris) or -mthreads (Mingw32)"
In file included from /usr/include/boost/thread/thread.hpp:12,
from /usr/include/boost/thread.hpp:13,
from ../main.cpp:8:
/usr/include/boost/thread/detail/platform.hpp:67: error: #error "Sorry, no boost threads are available for this platform."
In file included from /usr/include/boost/thread.hpp:13,
from ../main.cpp:8:
/usr/include/boost/thread/thread.hpp:19: error: #error "Boost threads unavailable on this platform"
and so on, a lot of more errors related to boost.
I tried to add -pthread, -pthreads, -lpthreadto where I thought I could, but did not solve the problem.
I forgot to mention, that I try to build the project in eclipse, I don't work in the command line, but I also tried g++ -pthread main.cpp and it gives the exact same error.
Please give detailed or stepbystep solution, because some things you answer here are simply chinese to me. I just want to get a simple thing running and don't even understand the problem. Don't even understand that error message, what does it want me to do.
basically what I did: install eclipse, write the above things in a new project, install libboost 1.4 using sinaptic pkg manager, and restarted everything and tried to compile. I got the error. Don't see what's happening, or what am I missing. (I have libc-dev)
Stack is really flowing over now. need some sleep to cool down. thank you guys for help!
等等，还有很多与 boost 相关的错误。我试图添加-pthread, -pthreads,-lpthread到我认为可以的地方，但没有解决问题。我忘了提及，我尝试在 eclipse 中构建项目，我不在命令行中工作，但我也尝试了 g++ -pthread main.cpp，它给出了完全相同的错误。请给出详细的或逐步的解决方案，因为您在这里回答的某些内容对我来说只是中文。我只是想让一个简单的东西运行起来，甚至不明白这个问题。甚至不明白那个错误信息，它要我做什么。基本上我做了什么：安装eclipse，在一个新项目中编写上述内容，使用sinaptic pkg manager安装libboost 1.4，然后重新启动一切并尝试编译。我得到了错误。不要看到发生了什么，或者我错过了什么。（我有 libc-dev）堆栈现在真的流过了。需要睡一会冷静下来。

As the error message say: pass -pthreadto the compiler:
正如错误消息所说：传递-pthread给编译器：
g++ -pthread yourfile.cpp
Also, for debian, make sure you have libc-devinstalled.
另外，对于 debian，请确保您已libc-dev安装。

#include <boost/thread.hpp>
int main(int argc, char *argv[]) {
return 0;
}
Compile with g++ test.cpp -pthread -lboost_thread.
用g++ test.cpp -pthread -lboost_thread.

The issue is a well known one from such an old version of boost. You are compiling with gcc/g++ 4.7, where the reference to pthreads have changed to GLIBCXX_HAS_GTHREADS, so boost is unable to find pthreads and disable it.
这个问题是来自如此旧版本的 boost 的一个众所周知的问题。您正在使用 gcc/g++ 4.7 进行编译，其中对 pthreads 的引用已更改为 GLIBCXX_HAS_GTHREADS，因此 boost 无法找到 pthreads 并禁用它。
So you have two options:
所以你有两个选择：
1) Upgrade boost_dev to last release (I think it's fixed in 1.50+).
1) 将 boost_dev 升级到最新版本（我认为它在 1.50+ 中已修复）。
2) Patch your boost include files (I've done this); just edit
2）修补你的boost包含文件（我已经完成了）；只是编辑
"your boost folder"/include/config/stdlib/libstdcpp3.hpp
“你的 boost 文件夹”/include/config/stdlib/libstdcpp3.hpp
and change:
并改变：
#ifdef __GLIBCXX__ // gcc 3.4 and greater:
# if defined(_GLIBCXX_HAVE_GTHR_DEFAULT) \
|| defined(_GLIBCXX__PTHREADS)
//
// If the std lib has thread support turned on, then turn it on in Boost
// as well. We do this because some gcc-3.4 std lib headers define _REENTANT
// while others do not...
//
# define BOOST_HAS_THREADS
# else
# define BOOST_DISABLE_THREADS
# endif
to add the new directive in the condition:
在条件中添加新指令：
#ifdef __GLIBCXX__ // gcc 3.4 and greater:
# if defined(_GLIBCXX_HAVE_GTHR_DEFAULT) \
|| defined(_GLIBCXX__PTHREADS) \
|| defined(_GLIBCXX_HAS_GTHREADS) // gcc 4.7
//
// If the std lib has thread support turned on, then turn it on in Boost
// as well. We do this because some gcc-3.4 std lib headers define _REENTANT
// while others do not...
//
# define BOOST_HAS_THREADS
# else
# define BOOST_DISABLE_THREADS
# endif

You need to install the boost thread libraries:
您需要安装 boost 线程库：
sudo apt-get install libboost-thread-dev
