提问by lolibility
I'm trying to install armadillo library onto my linux system(ubuntu 12.04). The BOOST BLAS ATLAS and LAPACK is required first for the installation. Is there a way to check if those libraries are already installed or not?

All these libraries are in the default repository, so you can easily get them by
所有这些库都在默认存储库中，因此您可以通过以下方式轻松获取它们
sudo apt-get install liblapack3
etc. I understand that this is not quite an answer to your question, but this is what you will probably have to do anyway. In case you still want to check if a package (any, not just libraries listed above) is installed, just run
等等。我知道这不是您问题的完整答案，但无论如何您都可能必须这样做。如果您仍然想检查是否安装了包（任何，而不仅仅是上面列出的库），只需运行
apt-cache policy liblapack3
