我已经通过 Homebrew 软件在我的 Mac(使用 Mac OS 10.9/Mavericks)上安装了 gdb 并成功地对其进行了代码签名。
在使用 gdb 开始调试 session 之前，我像这个例子一样编译了我的 C 文件:
gcc -g test.c -o test
之后我调用了 gdb:
Users-MacBook-Pro:Test User$ gdb ./test

done.
调用 gdb 命令如 r 或 sta 总是导致以下错误:
(gdb) r
Abort trap: 6
问题是什么？有什么解决办法吗？
最佳答案
我建议从头开始重建 gdb。您可以随时尝试自己安装，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
使用前记得先签名:https://gcc.gnu.org/onlinedocs/gcc-4.8.1/gnat_ugn_unw/Codesigning-the-Debugger.html
这样，您就可以轻松地调试代码。安装详情请看这里:Running GDB in macOS sierra
