问题
I have had problems with my IDE since an update to GCC 10.1 a few days ago. I use CLion, which uses clang-tidy as linter. I also use the newly introduced command target_precompiled_headers from CMake to use PCH for my project. Unfortunately I get weird linter warning and error messages:
That's how I include the header file for my pch in my CMakeLists.txt:
target_precompile_headers(Peach PRIVATE ${PROJECT_SOURCE_DIR}/Src/peach_pch.h)
Strangely enough, my program compiles perfectly. So the error messages must (obviously) be wrong. This is very irritating for me and my development process. With GCC 9 I did not have these problems. Unfortunately I have no possibility to downgrade at the moment. Also with Clang 10 the same problem occurs. Without PCH the error messages do not appear. But I do not want to work without it.
I've already done a lot of research. There is an open bug for clang: bugs.llvm.org. But I really don't know whether this is the problem or something else. It is hard to find out if the error is in CLion, GCC, Clang or something else. I only observed that with GCC 10.1 the error occurred for the first time.
Maybe someone has an idea or at least the same issue.
EDIT:
I kinda solved the issue by myself. I used the C++20 standard within my CMakeLists.txt:
set(CMAKE_CXX_STANDARD 20)
When I switch to C++17 the "error" messages disappeared. I had the guess, that there are some overlaps in the std lib since std::ranges (the error from the picture) exists since C++20.
So I think it could be a bug in the latest version of GCC?
