Eclipse CDT Auto Include Shared Libraries
提问by James
I am working in Eclipse: Helios Service Release 1 using Eclipse CDT compiling using g++
我在 Eclipse 中工作：Helios Service Release 1 using Eclipse CDT compile using g++
I have just started to have a go at using Shared Libraries in my projects but have run into a little problem. I have three projects A, B and C. A and B are both Shared Libraries and C is an executable.
我刚刚开始尝试在我的项目中使用共享库，但遇到了一个小问题。我有三个项目 A、B 和 C。A 和 B 都是共享库，C 是可执行文件。
Under eclipse I have managed to reference A and B from C and C compiles and runs correctly but when I try and run the generated C program manually outside of Eclipse I get the following error:
在 Eclipse 下，我设法从 C 和 C 中引用 A 和 B 编译并正确运行，但是当我尝试在 Eclipse 之外手动运行生成的 C 程序时，出现以下错误：
"error while loading shared libraries: libA.so: cannot open shared object file: No such file or directory"
“加载共享库时出错：libA.so：无法打开共享对象文件：没有这样的文件或目录”
I have tried moving A.so B.so and C into the same folder and run C but I get the same error.
我曾尝试将 A.so B.so 和 C 移动到同一个文件夹中并运行 C，但我遇到了同样的错误。
Can I get Eclipse to build my project with all the files in the same place and them still run when I move them to a new location?
我是否可以让 Eclipse 使用同一位置的所有文件构建我的项目，并且当我将它们移动到新位置时它们仍然运行？

Run ldconfigas root to update the cache - if that still doesn't help, you need to add the path to the file ld.so.conf(just type it in on its own line) or better yet, add the entry to a new file (easier to delete) in directory ld.so.conf.d.
ldconfig以 root 身份运行以更新缓存 - 如果这仍然没有帮助，您需要添加文件路径ld.so.conf（只需在其自己的行中输入）或者更好的是，将条目添加到新文件（更容易删除） ) 在目录中ld.so.conf.d。

You just need to set LD_LIBRARY_PATHto include the folder in which the shared libraries are.
Something like this: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/user/lib/
您只需要设置LD_LIBRARY_PATH为包含共享库所在的文件夹。像这样的东西：export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/user/lib/
