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

问题描述

我有一个二进制和一个共享库。
共享库编译时使用：

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

二进制文件编译时使用：

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

LDFLAGS = -lmisc

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

我设置在〜/ .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：

gdb mainx

但是从Emacs22启动gdb失败，并显示以下消息：

启动程序：/ mnt / sda5 /编译/ 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：没有这样的文件或目录

这看起来很棘手，我不能解决它。我不知道这是一个emacs的问题，或者我应该在gdb的命令行中传递一个参数。请与我分享您的想法。

解决方案

Emacs在它调用gdb之前不读取.bashrc。尝试在您的.gdbinit文件中设置set solib-search-path和set solib-absolute-path

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

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

the binary is compiled with:

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

LDFLAGS=-lmisc

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

I set in ~/.bashrc export LD_LIBRARY_PATH=/mnt/sda5/Programming/misc/src/ to the libmisc.so output path.

Debugging from console works fine:

gdb mainx

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

"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"

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. Please share your ideas with me.

解决方案

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
