用gdb调试Rust [英] Debugging Rust with gdb
问题描述
我知道StackOverflow上的这个调试Rust 问题,而且我还在Go之前使用过gdb。但是,我遇到一个问题,似乎gdb无法找到调试符号。
I'm aware of the debugging Rust questions here on StackOverflow and I also used gdb before with Go. However, I'm running into a problem where it seems gdb is unable to locate the debug symbols.
在 main.rs中考虑这个复杂的程序
?
pub fn main () {
println!("run");
}
我用调试符号编译它
rustc -g main.rs
然后我运行gdb
gdb main
这给出了第一个线索,加载调试符号的东西不太正确。
This gives the first clue that something with the loading of debug symbols is not quite right.
现在,当我在gdb并键入
Now when I'm in gdb and type
list
留下一些C代码,这不是我期望的。
it leaves me with some C code which isn't what I expect.
我做错了什么?我的gdb版本是7.7,我在OS X 10.9.2(13C64)上。我的rustc版本是rustc 0.11.0-pre(3035d8dfb13077e195eb056568183911c90c1b4b 2014-07-02 21:26:40 +0000)
What am I doing wrong? My gdb version is 7.7 and I'm on OS X 10.9.2 (13C64). My rustc version is rustc 0.11.0-pre (3035d8dfb13077e195eb056568183911c90c1b4b 2014-07-02 21:26:40 +0000)
它也可能有助于看到的输出`gdb --configuration``
It may also be helpful to see the output of `gdb --configuration``
$ gdb --configuration
This GDB was configured as follows:
configure --host=x86_64-apple-darwin13.1.0 --target=x86_64-apple-darwin13.1.0
--with-auto-load-dir=:${prefix}/share/auto-load
--with-auto-load-safe-path=:${prefix}/share/auto-load
--with-expat
--with-gdb-datadir=/usr/local/share/gdb (relocatable)
--with-jit-reader-dir=/usr/local/lib/gdb (relocatable)
--without-libunwind-ia64
--without-lzma
--with-python=/System/Library/Frameworks/Python.framework/Versions/2.7
--with-separate-debug-dir=/usr/local/lib/debug (relocatable)

--without-babeltrace
推荐答案
相同的问题,以后Rust版本(1.0.0-beta),完全不同答案:
Same question, later Rust version (1.0.0-beta), totally different answer:
在GDB中调试一个Rust可执行文件时, break main
在某些设置代码中设置断点Rust标准库的一部分。这不是你想要的。
In GDB, when debugging a Rust executable, break main
sets a breakpoint in some setup code that is part of the Rust standard library. This isn't what you want.
而是键入: break $ YOUR_CRATE :: main
,用您的程序 $ YOUR_CRATE
。
Instead type: break $YOUR_CRATE::main
, substituting the name of your program for $YOUR_CRATE
.
