中止陷阱6:在Mac OS上运行gdb时

Question

我已经通过自制软件在我的Mac(使用Mac OS 10.9/Mavericks)上安装了gdb并成功对其进行了编码.

在使用gdb启动调试会话之前,我编译了我的C文件,如下例所示:

gcc -g test.c -o test

之后我打电话给gdb:

Users-MacBook-Pro:Test User$ gdb ./test

done.

调用像r或sta这样的gdb命令总会导致以下错误:

(gdb) r 
Abort trap: 6

问题是什么？任何想法如何解决它？

我建议gdb从头开始重建。您始终可以尝试自己安装，而不是使用一些预构建的安装：

mkdir src
cd src
curl "http://ftp.gnu.org/gnu/gdb/gdb-8.0.tar.gz" -o gdb-8.0.tar.gz
tar zxf gdb-8.0.tar.gz
cd gdb-8.0
./configure --prefix=$HOME/opt/usr/local
make
make install

请记住在使用之前对其进行签名：https://gcc.gnu.org/onlinedocs/gcc-4.8.1/gnat_ugn_unw/Codesigning-the-Debugger.html

这样，您就可以轻松调试代码。有关安装的详细信息，请查看此处：在 macOS sierra 中运行 GDB
