mac下配置gdb调试golang

"liteide里面配置gdb为新的路径即可" -- 这是神马意思？

运行不了

请问上面这个“Warning:\nCannot insert breakpoint -1.\nCannot access memory at address 0xf782\n" (gdb)“怎样解决

重新安安装gdb brew reinstall gdb

根据提示添加~/.gdbinit文件 echo "set startup-with-shell off" >> ~/.gdbinit

然后签名 codesig -s gdb-cert /usr/local/bin/gdb

再通过liteide 选择gdb调试还是会报错，信息提示如下： =thread-group-added,id="i1" ~"GNU gdb (GDB) 8.1\n" ~"Copyright (C) 2018 Free Software Foundation, Inc.\n" ~"License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>\nThis is free software: you are free to change and redistribute it.\nThere is NO WARRANTY, to the extent permitted by law.

请各位前辈大虾多多指点，先谢谢了！

测试发现macos 10.13.4下更新的gdb(8.1)调试有问题，这个坑耽误我不少时间，最后使用gdb8.0就可正常调试，希望该贴帮助到更多的人。

本人系统下有两个版本的gdb(8.1和8.0） 解决办法： 1.果断删除/usr/local/bin/gdb 这个软链接文件 (rm -f /usr/local/bin/gdb) 2.重新建立软链接文件 ln -s /usr/local/Cellar/gdb/8.0/bin/gdb /usr/local/bin/gdb 3.重新签名gdb(8.0) codesign -s gdb-cert /usr/local/bin/gdb

这样就搞定！
