GDB无法加载，因此文件和错误没有这样的文件或目录 [英] GDB failed to load so files and errors No such file or directory
问题描述
我正在将带有高山linux的核心文件加载到Docker容器内的GDB中。
最初，我的gdb抱怨找不到二进制文件，然后我按照此讨论 gdb在启动程序期间，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，但是现在我遇到了同样的错误。这样的文件。我可以看到.so文件位于solib-search-path上设置的路径中，但是gdb没有加载任何库，并且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.
二进制文件在生产主机上运行，库位于路径
中，我通过设置solib-search-path
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在开发主机上运行二进制文件二进制表示未找到期望的库，因为这是开发主机
ldd binary says libraries not found which is expected since this is a development host
推荐答案
binary在生产主机所在的库所在的路径上，我通过设置solib-search-path
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
在开发主机上运行二进制文件是您的问题所在。
There is your problem right here.
solib-search-path 是 GDB 会查找库。
在中不会影响二进制文件本身，二进制文件使用标准系统库路径编译，在 DT_RPATH 或 LD_LIBRARY中_PATH 环境变量来搜索共享库。
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 仅应在分析来自其他主机的核心转储时设置（GDB需要访问生成核心转储时使用的确切库）。不必在运行本地二进制文件时设置 solib-search-path － GDB可以通过询问运行时加载器的位置来自动推断出库的位置。
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二进制文件表示未找到库，因为这是开发主机，因此是预期的
ldd binary says libraries not found which is expected since this is a development host
如果 ldd 这样说，那么当然您将无法运行二进制文件（在GDB外部）
If ldd says that, then of course you will not be able to run the binary (inside of outside GDB).
