gdb 说“无法打开共享对象文件"； [英] gdb says "cannot open shared object file"

问题描述

我有一个二进制文件和一个共享库.共享库编译为:

I have one binary and one shared library. The shared library is compiled with:

all:
g++ -g -shared -fpic $(SOURCES) -o libmisc.so

二进制文件编译为:

LIBS=-L../../misc/src

LDFLAGS=-lmisc

all:
g++ -g -o mainx $(INCLUDE) $(SOURCE) $(LIBS) $(LDFLAGS)

我在~/.bashrc

export LD_LIBRARY_PATH=/mnt/sda5/Programming/misc/src/

到 libmisc.so 输出路径.

从控制台调试工作正常:

Debugging from console works fine:

gdb mainx

但是，从 Emacs22 启动 gdb 失败并显示以下消息:

However from Emacs22, launching gdb fails with the following message:

启动程序:/mnt/sda5/Programming/main/src/mainx/mnt/sda5/Programming/main/src/mainx:加载共享库时出错:libmisc.so:无法打开共享对象文件:没有那个文件或目录

Starting program: /mnt/sda5/Programming/main/src/mainx /mnt/sda5/Programming/main/src/mainx: error while loading shared libraries: libmisc.so: cannot open shared object file: No such file or directory

这暂时看起来很棘手，我无法解决.我不确定这是否是 emacs 的问题，或者我应该在 gdb 的命令行中传递一个参数.

This looks very tricky for the moment, and I couldn't solve it. I am not sure if this a emacs's problem, or I should pass a parameter in gdb's command line.

推荐答案

Emacs 在调用 gdb 之前可能不会读取您的 .bashrc.尝试将 'set solib-search-path' 和 'set solib-absolute-path 放在您的 .gdbinit 文件中

Emacs probably does not read your .bashrc before it invokes gdb. Try to put 'set solib-search-path' and 'set solib-absolute-path in your .gdbinit file instead
