ld 找不到 -l<library>; [英] ld cannot find -l&lt;library&gt;

问题描述

我在 ubuntu 12.04 上安装 pyipopt 时遇到问题.在链接期间，我收到错误:

<上一页>/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/中可用

有人对此有解决方案吗?

下面是运行 setup.py build 的完整返回:

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.
