程序编译精细与boost libs，但运行时错误 [英] Program compiles fine with boost libs, but error when running it

问题描述

简而言之...

C ++程序（使用boost库）在Eclipse中编译良好，但随后加载共享库时出错：libboost_thread.so。

详细信息

/ h1>

我正在C ++上运行一个基本程序，以检查是否可以正确使用boost线程库。

  #include< boost / thread / thread.hpp> 
 #include< iostream> 
 
 void hello（）
 {
 Std :: cout<<Hello，I am a thread<< std :: endl; 
} 
 
 int main（）
 {
 boost :: thread th1（& hello）; 
 th1.join（）; 
} 
  

代码编译正常，所以我相信我已经安装并设置了但是当我尝试运行程序时，我在控制台中得到以下错误消息

 错误加载共享库时：libboost_thread.so.1.46.1：无法打开共享对象文件：无此类文件或目录
  
 
 
解决方案
我有一个非常类似的问题FreeFileSYnc，编译良好，但不会启动由于libboost线程错误：
  FreeFileSync：加载共享库时出错：libboost_thread.so.1.51.0：无法打开共享对象文件：否这样的文件或目录
  
为了修复它，我做了：
  sudo ldconfig / usr / local / lib 
  
它可能会帮助其他人。
 
In a nutshell...

C++ program (using the boost libraries) compiles fine in Eclipse, but then "error while loading shared libraries: libboost_thread.so.1.46.1: cannot open shared object file: No such file or directory" it shown when running it.



Details

I am running a basic program on C++ to check that I can use the boost threading libraries correctly.
#include <boost/thread/thread.hpp>
#include <iostream>

void hello ()
{
    Std::cout<<"Hello, I am a thread"<<std::endl;
}

int main ()
{
    boost::thread th1(&hello);
    th1.join();
}
The code compiles fine, so I believed that I had installed and set up the boost libraries correctly (added directories to include etc)

However when I try to run the program I get the following error message in the consol
error while loading shared libraries: libboost_thread.so.1.46.1: cannot open shared object file: No such file or directory

解决方案
I had a very similar issue with FreeFileSYnc, compiles fine but won't launch due to a libboost thread error :
FreeFileSync: error while loading shared libraries: libboost_thread.so.1.51.0: cannot open shared object file: No such file or directory
To fix it I did :
sudo ldconfig /usr/local/lib
It may help other people.
