  本文介绍ubuntu系统环境下coredump文件的分析方法。

**一个coredump示例：**

## 1.2. gdb查看堆栈信息
|

|

**Ubuntu系统需要加sudo执行程序才会生成coredump文件。**
|
||||
|
||||
### 1.2.1. 无法识别coredump文件
|
||||
|
||||
  在gdb中无法识别coredump文件，如下所示：
|
||||
|
||||
```
|
||||
$ sudo gdb ../output_files/test/bin/McuManagerTest core.smbd.3390383

||||

Sorry, try again.

```
|
||||
|
||||
由于gdb和asan同时启用会冲突，导致无法识别coredump文件。解决办法如下：
|
||||
|
||||
```
|
||||
# Gdb debug
|
||||

|
||||

|
||||
SET(CMAKE_BUILD_TYPE "Debug")
|
||||

|
||||

|
||||

|
