/usr/bin/ld: cannot find -lcurl
提问by Michiel de Mare
I'm trying to install the ruby gem for curl (curb) on Ubuntu 10.10, but during the installation, I get the error:
我正在尝试在 Ubuntu 10.10 上为 curl (curb) 安装 ruby gem，但是在安装过程中，出现错误：
/usr/bin/ld: cannot find -lcurl
But curl is installed! apt-get install curl says I've got the newest version. There is no curl-dev either.
但是curl安装了！apt-get install curl 说我有最新版本。也没有 curl-dev。
I'm getting these kinds of errors all the time, with curl, with libxml, with readline, and I have no idea what's going on. Something is wrong with my installation of Ubuntu, but I don't know what, I don't know where to look, I don't know what to google for, and I don't know how to fix it.
我一直在收到这些类型的错误，使用 curl、使用 libxml、使用 readline，我不知道发生了什么。我安装的 Ubuntu 出了点问题，但我不知道是什么，我不知道去哪里找，我不知道要谷歌搜索什么，我不知道如何修复它。
Help would be deeply appreciated.
帮助将不胜感激。
EDIT: this is in my /usr/lib dir for libcurl:

You need the libcurl3-dev package. Curl is just the command line utility. The library is libcurl3, and it has a -dev package. (It seems to be a virtual package in Maverick, redirecting to libcurl4-openssl-dev, but that should still work or the virtual package would not have been provided.) Indeed from your lib directory I can see that libcurl3 is merely a symbolic link to libcurl4. (libcurl3-dev may not be available in the future, so use libcurl4-openssl-dev directly).
您需要 libcurl3-dev 包。Curl 只是命令行实用程序。库是 libcurl3，它有一个 -dev 包。（它似乎是 Maverick 中的一个虚拟包，重定向到 libcurl4-openssl-dev，但这应该仍然有效，否则不会提供虚拟包。）确实从你的 lib 目录中我可以看到 libcurl3 只是一个符号链接到 libcurl4。（libcurl3-dev 以后可能不可用，所以直接使用 libcurl4-openssl-dev）。
