Linux C ++链接器/usr/bin/ld [英] Linux C++ linker /usr/bin/ld

问题描述

我使用g ++ 4.4.6在Redhat Linux 6上编写了一个小应用程序.编译后，我收到一个错误

I wrote a small application on Redhat Linux 6 using g++ 4.4.6. After compilation, I received an error

/usr/bin/ld: cannot find -lcrypto

我搜索了加密货币库，然后在这里找到了

I did a search for the crypto library and find them here,

[root@STL-DUNKEL01 bin]# find / -name libcrypto*
/usr/lib64/libcrypto.so.0.9.8e
/usr/lib64/libcrypto.so.10
/usr/lib64/libcrypto.so.6
/usr/lib64/libcrypto.so.1.0.0

我的问题是，编译错误是否由/usr/bin/ld 引起，而不是在搜索路径中没有/usr/lib64/?如果是，该如何添加?

My question is whether the compilation error is caused by /usr/bin/ld not having /usr/lib64/ in the search path? If yes, how can I add it?

谢谢.

推荐答案

像-L<directory_to_search_in>一样，您可以提供目录以作为gcc的参数来搜索库.请注意，-L可以有多个参数.另外，您是要构建32位应用程序还是构建64位应用程序?

You can provide the directories to search for the libraries in as a parameter to gcc like so -L<directory_to_search_in>. And note that there can be multiple parameters to -L. Also, are you trying to build a 32-bit application or a 64-bit one?
