GDB 无法加载 so 文件和错误 没有此类文件或目录 [英] GDB failed to load so files and errors No such file or directory

问题描述

我正在使用 alpine linux 将核心文件加载到 docker 容器内的 GDB 中.最初我的 gdb 抱怨找不到二进制文件，然后我跟着这个讨论 gdb 在启动程序以代码 127 退出并安装了 libc6-compat，即使我有 64 位 linux 并且我的二进制解释器是 64 位 [请求程序解释器:/lib64/ld-linux-x86-64.so.2]

I am loading a core file into GDB inside a docker container with alpine linux. Initially my gdb complained about binary not found, then i followed this discussion gdb During startup program exited with code 127 and installed libc6-compat, even though I have a 64-bit linux and my interpreter for the binary is 64-bit [Requesting program interpreter: /lib64/ld-linux-x86-64.so.2]

这确实有效，但现在我遇到了 .so 文件的相同错误.我可以看到 .so 文件在 solib-search-path 上设置的路径中，但 gdb 没有加载任何库并抱怨没有这样的文件或目录.

That actually worked but now i get the same error for the .so files. I can see that .so files are in the path set on solib-search-path but gdb did not load any of the libraries and complains No such file or directory.

二进制文件在库所在路径的生产主机上运行我通过设置 solib-search-path 在开发主机上运行二进制文件

binary runs on a production host where the libraries are in the path I am running the binary on a development host by setting the solib-search-path

ldd 二进制表示未找到库，这是预期的，因为这是一个开发主机

ldd binary says libraries not found which is expected since this is a development host

推荐答案

二进制文件在生产主机上运行，​​其中库所在的路径我通过设置 solib-search-path 在开发主机上运行二进制文件

binary runs on a production host where the libraries are in the path I am running the binary on a development host by setting the solib-search-path

你的问题就在这里.

solib-search-path 是 GDB 查找库的路径.

The solib-search-path is the path where GDB will look for libraries.

绝不会该设置会影响二进制文件本身，它使用标准系统库路径、编译入的 DT_RPATH 或 LD_LIBRARY_PATH用于搜索共享库的环境变量.

In no way does that setting affect the binary itself, which uses either standard system library path, compiled-in DT_RPATH, or LD_LIBRARY_PATH environment variable to search for shared libraries.

通常，solib-search-path 应该只在您分析来自其他主机的核心转储时设置(GDB 需要访问准确的库，生成核心转储时使用).在运行本地二进制文件时设置 solib-search-path 永远不是必需的——GDB 可以通过询问运行时加载器的位置来自动推断库的位置.

Usually, solib-search-path should only be set when you are analyzing a core dump that came from some other host (GDB needs access to the exact libraries that were used when the core dump was generated). Setting solib-search-path while running a local binary should never be ncessary -- GDB can automatically deduce where the libraries are by asking the runtime loader where they are.

ldd 二进制表示未找到库，这是预期的，因为这是一个开发主机

ldd binary says libraries not found which is expected since this is a development host

如果 ldd 这么说，那么当然你将无法运行二进制文件(在 GDB 之外).

If ldd says that, then of course you will not be able to run the binary (inside of outside GDB).
