gdb说“无法打开共享对象文件”-gdbsays“cannotopensharedobjectfile”

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

在调用gdb之前,Emacs可能不会读取.bashrc。尝试将'set solib-search-path'和'set solib-absolute-path设置为.gdbinit文件

Emacs doesn't invoke gdb via bash, but rather invokes it directly, and so .bashrc changes do not take effect and LD_LIBRARY_PATH is not set.

Emacs不会通过bash调用gdb,而是直接调用它,因此.bashrc更改不会生效,并且未设置LD_LIBRARY_PATH。

If you quit emacs, open a new shell (so LD_LIBRARY_PATH is set), start emacs in it, and then do M-X gdb, then it would work.

如果你退出emacs,打开一个新的shell(所以设置了LD_LIBRARY_PATH),在其中启动emacs,然后执行M-X gdb,那么它就可以了。

Setting solib-search-path in GDB is a hack.

在GDB中设置solib-search-path是一种破解。

A much better fix is to build the executable in such a way that it doesn't need LD_LIBRARY_PATH to begin with:

更好的解决方法是以不需要LD_LIBRARY_PATH开头的方式构建可执行文件:

LDFLAGS=-lmisc -Wl,-rpath=/mnt/sda5/Programming/misc/src

Another way is to create a .gdbinit file in your $HOME and set the LD_LIBRARY_PATH there:

另一种方法是在$ HOME中创建一个.gdbinit文件,并在那里设置LD_LIBRARY_PATH:

# file .gdbinit
set env LD_LIBRARY_PATH=/mnt/sda5/Programming/misc/src/

This is convenient if you need to debug with that LD_LIBRARY_PATH frequently (and don't want to remember running emacs from your shell every time).

如果您需要经常使用LD_LIBRARY_PATH进行调试(并且不想记住每次都从shell运行emacs),这很方便。
