gdb 无法打开共享对象文件 [英] gdb can not open shared object file

问题描述

我正在尝试从控制台开始调试我的应用程序.

I am trying to debug my application starting from console.

> gdb ./Geod

然后在 gdb 中

(gdb) run

我得到了输出:

error while loading shared libraries: libGeo.Cored.so.1: 
cannot open shared object file: No such file or directory

系统配置如下:

> echo $LD_LIBRARY_PATH
    /home/paceholder/projects/geo/lib/debug

> ls $LD_LIBRARY_PATH
    libGeo.Cored.so.1.0.0
    libGeo.Cored.so 
    libGeo.Cored.so.1
    libGeo.Cored.so.1.0


(gdb) show solib-search-path
    The search path for loading non-absolute shared library symbol files is
    /home/paceholder/projects/geo/lib/debug.

推荐答案

您可以在 gdb 中使用 set environment 命令来更改 gdb 用于启动您要调试的程序的环境.摘自 gdb 帮助:

You can use the set environment command in gdb to change the environment gdb uses to launch the program you want to debug. Extract from the gdb help:

(gdb) help set environment 
Set environment variable value to give the program.
Arguments are VAR VALUE where VAR is variable name and VALUE is value.
VALUES of environment variables are uninterpreted strings.
This does not affect the program until the next "run" command.

LD_LIBRARY_PATH 示例:

(gdb) set environment LD_LIBRARY_PATH /home/paceholder/projects/geo/lib/debug
