使用CAST AST解析器忽略丢失的标头 [英] Ignore missing headers with clang AST parser
问题描述
我在Windows上，使用MSVC编译我的项目，但我需要使用clang进行整洁的AST解析器，这使我可以编写一些代码生成器。
问题是，clang无法解析MSVC标头（一个众所周知的和可以理解的问题）。
I'm on Windows, using MSVC to compile my project, but I need clang for its neat AST parser, which allow me to write a little code generator.
Problem is, clang cannot parse MSVC headers (a very-well known and understandable problem).
我尝试了两种选择：
- 我包括MSVC标头文件夹，解析代码中包含的内置标头将最终导致致命错误，从而使我无法正确解析我想要的部分。
- 我之前所做的只是不提供任何内置标头，而是向前声明我需要的类型。它运行良好，并且以某种方式在最新的Clang中不再可用。我真的不知道丢失标头的解析器策略是否已更改，但是每次包含
< string>之类的东西而导致解析失败时，它都会导致完全失败。
- I include MSVC header folder, parsing the built-in headers included in my code will end-up leading to a fatal error at some point, preventing me from parsing the parts I want correctly.
- What I did before is simply not provide any built-in headers and forward declare the types I needed. It worked fine and somehow it doesn't anymore with latest Clang. I don't really know if the parser policy on missing header changed, but it is causing complete failure every time something like
<string>is included and not much get parsed.
我正在使用python绑定（libclang），但如果有解决方案，我会考虑切换到C / C ++ API
I am using the python bindings (libclang), but I would consider switching to C/C++ API if there would be a solution there.
无论如何，我是否可以更改此行为，并使clang继续解析，即使未找到某些标头？
Is there anyway I can alter this behavior and make clang continue parsing even when some headers are not found ?
推荐答案
使用SetSuppressIncludeNotFoundError。花了我一个小时才找到！您可以想象我能多么高兴找到它！
Use SetSuppressIncludeNotFoundError. Took me an hour to find! You can imagine how glad I was to find it!
