在Linux上安装RQuantLib [英] Installing RQuantLib on Linux

问题描述

我们一直在尝试在Redhat Linux机器上安装RQuantLib.经过一个月(令人尴尬的长时间！)的反复试验，我们成功地编译了最新版本的boost和quantlib.我根本不是Linux专家，因此我在运行install.packages("RQuantLib")时调试编译标志时遇到了一些麻烦. Rcpp已安装并正常运行.

We have been trying to install RQuantLib on a redhat linux machine. After a month (embarassingly long time!) of trial and error, we have succesfully compiled the latest version of boost and also quantlib. I am not a linux expert at all, so I am having a little trouble debugging the compile flags when I run install.packages("RQuantLib"). Rcpp is installed and working perfectly as well.

以下错误消息详细说明了该问题.我很困惑，因为我认为它想要的文件(libQuantLib.so.0)存在于/usr/local/lib中.抱歉，这很可能是一个愚蠢的问题，但是我认为我们非常接近可以在Linux上的R中访问Quantlib.

The error message below details the issue. I am confused because the file I think it should want (libQuantLib.so.0) exists in /usr/local/lib. Sorry that this is most likely a stupid question, but I think we are very close to having access to quantlib in R on linux.

错误消息如下:

推荐答案

可能只是动态加载程序尚未意识到您已添加QuantLib. 尝试添加行

It might just be that the dynamic loader hasn't realized yet that you've added QuantLib. Try adding the line

/usr/local/lib

到/etc/ld.so.conf(如果尚未存在)，然后运行

to /etc/ld.so.conf (if it's not already there) and then run

sudo ldconfig

在系统上，如果您想了解自己在做什么，应该同时有ld.so和ldconfig的手册页，这总是一个好主意.切勿执行互联网上陌生人给出的命令，尤其是在sudo模式下:)

On your system there should be man pages for both ld.so and ldconfig if you want to understand what you're doing, which is always a good proposition. Never execute commands given by strangers on the internet, especially in sudo mode :)

完成上述操作后，您应该可以加载libQuantLib.

After you do the above, you should be able to load libQuantLib.
