如何在Linux中正确链接Boost库 [英] How to link boost libraries properly in Linux

问题描述

我一直在尝试Boost教程，但是我陷于链接文件系统库的问题.

I've been trying to go through Boost tutorials but I got stuck at linking the filesystem library.

我有Ubuntu 12.10.安装并不难

I have Ubuntu 12.10. Installation wasn't that hard

sudo apt-get install libboost-all-dev

这会将所有标头放在/usr/local/include中，并将已编译的源代码放在/usr/lib/中
[--headers]
[--binaries]

This put all headers in /usr/local/include and compiled sources in /usr/lib/
[--headers]
[--binaries]

我写了这个程序[--program].当我尝试编译它时

I wrote this program [--program]. When I tried to compiled it

 g++ -g tut1.cpp -o tut1 -lboost_system -lboost_filesystem

忘记了以下错误:[--errors].
在 http://上稍作搜索后www.boost.org/doc/libs/1_53_0/more/getting_started/unix-variants.html
我试过了:

got this errors: [--errors].
After a little search on http://www.boost.org/doc/libs/1_53_0/more/getting_started/unix-variants.html
I tried this:

g++ -g -I /usr/local/include/boost/ tut1.cpp -o tut1 -L /usr/lib/libboost_filesystem.a -lboost_system -lboost_filesystem 

但是没有运气.我有同样的错误.

but didn't have luck. I had the same errors.

推荐答案

我在这里找到了答案:

看起来二进制文件不在/usr/lib中，而在/usr/local/lib中.
因此，正确的编译命令将是:

I found the answer myself here:
http://www.richelbilderbeek.nl/CppLinkErrorUndefinedReferenceToBoostFilesystemDetailGet_current_path_api.htm
Looks like binaries weren't in /usr/lib but in /usr/local/lib.
So the correct command for compilation would be:

g++ -g tut1.cpp -o tut1 -L/usr/local/lib/ -lboost_filesystem

@Yuushi，那是1个问题.

@Yuus that was 1 problem.
