Eclipse中的Boost链接错误 [英] Boost linkage error in Eclipse

问题描述

到目前为止的步骤：

我已经在我的Eclipse C ++项目中包含boost的线程功能。 >

从boost.org下载boost。

  ./ configure --with-libraries = system，thread 
 make 
 sudo make install 
 
 sudo ldconfig -v 
  

在eclipse项目中，将include目录设置为：

  / usr / local / include / boost -1_38 / 
  

在链接器中将库（-l）设置为boost_thread

将搜索路径（-L）设置为

  / usr / local / lib 
 

链接器运行，返回ld错误

  / usr / bin / ld：找不到-lboost_thread 
  

如下：

 调用：GCC C ++链接器
 g ++ -L / usr / local / lib -oboostHello3 ./src/boostHello3.o -lboost_thread 
 / usr / bin / ld：找不到-lboost_thread 
 collect2：ld返回1退出状态
  

以下是/ usr / local / lib中的相关条目：

  libboost_system-gcc43-mt-1_38.a 
 libboost_system-gcc43-mt-1_38.so 
 libboost_system-gcc43-mt-1_38.so.1.38.0 
 libboost_system-gcc43-mt.a 
 libboost_system-gcc43-mt.so 
 
 libboost_thread-gcc43-mt-1_38.a 
 libboost_thread-gcc43-mt-1_38.so 
 libboost_thread-gcc43-mt -1_38.so.1.38.0 
 libboost_thread-gcc43-mt.a 
 libboost_thread-gcc43-mt.so 
  

这里是/etc/ld.so.conf的内容

  include / etc / ld.so.conf.d / *。conf 
 / usr / local / lib 
  

链接器如何丢失这个？

解决方案

链接器行应该是 -lboost_thread-gcc43-mt-1_38 。

I've been banging my head fruitlessly against the wall attempting to include boost's thread functionality in my Eclipse C++ project on Ubuntu.

Steps so far:

Download boost from boost.org

./configure --with-libraries=system,thread
make
sudo make install

sudo ldconfig -v

In the eclipse project, set the include directory to:

/usr/local/include/boost-1_38/

In the linker set the library(-l) to "boost_thread"

Set the search path (-L) to

/usr/local/lib

Linker runs, returns with ld error

/usr/bin/ld: cannot find -lboost_thread

as follows:

Invoking: GCC C++ Linker
g++ -L/usr/local/lib -o"boostHello3"  ./src/boostHello3.o   -lboost_thread
/usr/bin/ld: cannot find -lboost_thread
collect2: ld returned 1 exit status

Here are relevant entries from /usr/local/lib:

libboost_system-gcc43-mt-1_38.a
libboost_system-gcc43-mt-1_38.so
libboost_system-gcc43-mt-1_38.so.1.38.0
libboost_system-gcc43-mt.a
libboost_system-gcc43-mt.so

libboost_thread-gcc43-mt-1_38.a
libboost_thread-gcc43-mt-1_38.so
libboost_thread-gcc43-mt-1_38.so.1.38.0
libboost_thread-gcc43-mt.a
libboost_thread-gcc43-mt.so

Here are the contents of /etc/ld.so.conf

include /etc/ld.so.conf.d/*.conf
/usr/local/lib

How is the linker missing this?

解决方案

Your linker line should be saying -lboost_thread-gcc43-mt-1_38.
