Qt5 "Clang Code Model" 一些设置

来源 https://www.cnblogs.com/cppskill/p/11745893.html

1、有些设置可能这里在设置了，到别的地方(例如换了一个机子) 又要设置，这样的话在不熟练的时候手动敲进去会比较慢，这里先记录下来以后要用直接复制就行了

2、Qt5.9.8 vs2017 ：Tools > Options > C++ > Code Model > Clang Code Model > Manage

　"Diagnostic Configuration" 默认选中的是 "Clang-only checks for almost everything [built-in]"，然后我将它 "Copy..."一下，名字命名为"Clang-only checks for almost everything (CopyByZC)"

　　于是它现在的内容为：

-Weverything -Wno-c++98-compat -Wno-c++98-compat-pedantic -Wno-unused-macros -Wno-newline-eof -Wno-exit-time-destructors -Wno-global-constructors -Wno-gnu-zero-variadic-macro-arguments -Wno-documentation -Wno-shadow -Wno-switch-enum -Wno-missing-prototypes -Wno-used-but-marked-unused

　然后再在 "Diagnostic Configuration"中选择 "Clang-only checks for almost everything (CopyByZC)"

3、后加的内容也记录下来，方便以后直接复制（而不用一直重复的手动一一敲入）

　3.1、20191120 里面的内容为：

-Weverything -Wno-c++98-compat -Wno-c++98-compat-pedantic -Wno-unused-macros -Wno-newline-eof -Wno-exit-time-destructors -Wno-global-constructors -Wno-gnu-zero-variadic-macro-arguments -Wno-documentation -Wno-shadow -Wno-switch-enum -Wno-missing-prototypes -Wno-used-but-marked-unused -Wno-old-style-cast -Wno-sign-conversion -Wno-deprecated-declarations -Wno-reserved-id-macro -Wno-undef -Wno-reorder -Wno-cast-qual -Wno-nonportable-system-include-path -Wno-cast-align -Wno-zero-as-null-pointer-constant -Wno-microsoft-goto

　3.2、20191127：

-Weverything -Wno-c++98-compat -Wno-c++98-compat-pedantic -Wno-unused-macros -Wno-newline-eof -Wno-exit-time-destructors -Wno-global-constructors -Wno-gnu-zero-variadic-macro-arguments -Wno-documentation -Wno-shadow -Wno-switch-enum -Wno-missing-prototypes -Wno-used-but-marked-unused -Wno-old-style-cast -Wno-sign-conversion -Wno-deprecated-declarations -Wno-reserved-id-macro -Wno-undef -Wno-reorder -Wno-cast-qual -Wno-nonportable-system-include-path -Wno-cast-align -Wno-zero-as-null-pointer-constant -Wno-microsoft-goto -Wno-format-nonliteral
