我在 ubuntu 12.04 上安装 pyipopt 时遇到问题。在链接期间，我收到错误:
/usr/bin/ld: cannot find -lcoinhsl
即使我知道这个库已经安装并且 .so 和 .la 文件在 /home/mostafa/MyBuilds/CoinIpopt/build/lib/
有人对此有解决方案吗？
下面是运行 setup.py build 的完整返回:

最佳答案
-Ldir
Add directory dir to the list of directories to be searched for -l.
关于gcc - ld 找不到 -l<库>，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12107422/
