ld找不到-l< library> [英] ld cannot find -l<library>

问题描述

我在安装Ubuntu 12.04上的pyipopt时遇到了问题。在链接期间，我收到错误：

 
 / usr / bin / ld：找不到-lcoinhsl 
 

尽管我知道这个库已经安装，并且.so和.la文件在 / home / mostafa / MyBuilds / CoinIpopt / build / lib /

没有人有解决方案吗？

解决方案

- Ldir

将目录dir添加到要搜索的目录列表中-l。

I am having trouble installing pyipopt on ubuntu 12.04. During linking, I receive the error:

/usr/bin/ld: cannot find -lcoinhsl

Even though I know that this library is installed and the .so and .la files are available in /home/mostafa/MyBuilds/CoinIpopt/build/lib/

does anyone have a solution for this?

below is the complete return of running setup.py build:

解决方案

-Ldir
Add directory dir to the list of directories to be searched for -l.
