如果我使用 g++作为我的编译器，我如何扫描 c++使用 clang 静态分析器创建文件？

我使用 g++ 编译我的 C++ 项目。当我尝试使用 clang 静态分析器 (scan-build) 检查我的代码，我收到错误：

>> scan-build g++ main.cpp
could not find clang line

How do I use the scan-build tool with g++?

看来 scan-build 无法将“g++”识别为编译器命令。它需要“clang”或“gcc”。如果将“g++”替换为“gcc -lstdc++”来构建项目，则扫描构建工具将正常工作。

>> scan-build gcc -lstdc++ main.cpp
main.cpp:7:3: warning: Assigned value is garbage or undefined
  int y = x;
  ^       ~
1 warning generated.
scan-build: 1 bugs found.
scan-build: Run 'scan-view /var/folders/2l/2l6vhCnVFNad-O8ryd5YO++++TI/-Tmp-/scan-build-2011-09-18-2' to examine bug reports.

It appears that scan-build is having trouble recognizing "g++" as the compiler command. It expects "clang" or "gcc". If you replace "g++" with "gcc -lstdc++" to build your project, the scan-build tool will work properly.

>> scan-build gcc -lstdc++ main.cpp
main.cpp:7:3: warning: Assigned value is garbage or undefined
  int y = x;
  ^       ~
1 warning generated.
scan-build: 1 bugs found.
