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 pathI 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
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.
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).
