###  ###

### 问题1：出现 Could not determine GDB version using command: gdb --version ###

##### 原因： #####

mac上没有安装gdb或者gdb位置配置有问题

##### 解决方法： #####

1 安装gdb，

2 如果确定已经安装了gdb，需要配置Eclipse中Debuger的路径：项目右键-》Debug As-》Debug Configurations-》左侧C++ Application找到当前项目-》右侧标签页选择Debuger-》修改gdb的路径和.gdbinit文件路径

### 问题2：出现 Could not determine GDB version using command: gdb --version ###

Error in final launch sequence  
    Failed to execute MI command:  
    -exec-run  
    Error message from debugger back end:  
    Unable to find Mach task port for process-id 99177: (os/kern) failure (0x5).  
     (please check gdb is codesigned - see taskgated(8))

1 具体步骤参考：[https://segmentfault.com/q/1010000004136334][https_segmentfault.com_q_1010000004136334]

2 如果出现系统证书创建失败的问题参照：[http://blog.csdn.net/lllkey/article/details/79423596][http_blog.csdn.net_lllkey_article_details_79423596]

###    问题3：出现 Could not determine GDB version using command: gdb --version ###

Error in final launch sequence
    Failed to execute MI command:
    -exec-run
    Error message from debugger back end:
    During startup program terminated with signal ?, Unknown signal.
    During startup program terminated with signal ?, Unknown signal.

##### 原因： #####

mac osx某个版本之后会出现的问题，修改.gdbinit文件的配置可以解决

##### 解决方法： #####

1 参考：[https://stackoverflow.com/questions/40052171/gdb-terminated-with-signal-unknown-signal][https_stackoverflow.com_questions_40052171_gdb-terminated-with-signal-unknown-signal]

在home目录或者gdb的目录下创建文件：.gdbinit (我的gdb的路径为：/usr/local/Cellar/gdb/8.1/bin)，只要之后再Eclipse中配置相应路径即可

echo "set startup-with-shell off" >> ~/.gdbinit

重新开一个terminal 或者 在Eclipse下再debug即可

###    问题4：出现 Could not determine GDB version using command: gdb --version ###

Error in final launch sequence
    Failed to execute MI command:
    -exec-run
    Error message from debugger back end:
    During startup program terminated with signal SIGTRAP, Trace/breakpoint trap.
    During startup program terminated with signal SIGTRAP, Trace/breakpoint trap.

##### 原因： #####

gdb8.1版本的某些问题，需要降到某版本，我现在尝试gdb8.0.1是可以调试的

##### 解决方法： #####

1 参考：[https://www.jianshu.com/p/b546a47b6b75 ][https_www.jianshu.com_p_b546a47b6b75]

从这个文章来看gdb8.1并不适配现在的os，所以需要回退到gdb8.0.1  
使用brew更换版本失败，由于其中需要用到  
brew versions gdb  
但是返回：  
Error: Unknown command: versions  
2 8.0.1下载地址： [https://ftp.gnu.org/gnu/gdb/gdb-8.0.1.tar.xz][https_ftp.gnu.org_gnu_gdb_gdb-8.0.1.tar.xz]  
开始编译安装gdb:  
解压：

tar -Jxvf /Users/lsq/Movies/thunder/gdb-8.0.1.tar.xz

编译安装：

./configure --prefix=/usr/local
    make
    make -C gdb install

签名gdb：

codesign -fs gdb_codesign $(which gdb)

配置：

echo "set startup-with-shell off" >> ~/.gdbinit

如果使用Eclipse调试：修改Debuger中gdb和.gdbinit的位置（参考问题1）
