出错处理

(1) 如果单步debug报类似错误：

Unable to write file ‘vscode-remote://wsl+ubuntu-18.04/build/glibc-OTsEL5/glibc-2.27/csu/libc-start.c’ (NoPermissions (FileSystemError): Error: ACCESS: permission denied, open…

$sudo mkdir -p /build/glibc-OTsEL5
$cd /build/glibc-OTsEL5
$sudo wget http://ftp.gnu.org/gnu/glibc/glibc-2.27.tar.gz
$sudo tar –zxvf glibc-2.27.tar.gz

(2) 如果报错：
#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (/build/glibc-OTsEL5/glibc-2.27/csu/libc-start.c).

解决：
新增c_cpp_properties.json文件，内容如下，其中”/usr/include”是手动添加的。
