用于启用详细和详细g ++警告的标志 [英] Flags to enable thorough and verbose g++ warnings

问题描述

通常在 gcc 下的C中，我将从以下一组警告标志开始（从多个来源痛苦地汇编）：

  -Wall -Wextra -Wformat-nonliteral -Wcast-align -Wpointer-arith -Wbad-function-cast \ 
 -Wmissing-prototypes -Wstrict-prototypes -Wmissing-declarations -Winline -Wundef \ 
 -Wnested-externs -Wcast-qual -Wshadow -Wwrite-strings -Wno-unused-parameter \ 
 -Wfloat-equal -pedantic -ansi 
 

我将使用这组警告来构建（至少是我的调试版本）并修复所有可能的一切），然后只有删除标志，如果它们不相关或不可固定（几乎没有）。有时，如果我在编译时不得不离开，我还会添加 -Werror 。

挑选C ++（是的，我在时间背后15年），我想从右脚开始。

我的问题是：有人有一个预编译类似的一组完整的警告标志为C ++在 g ++ ？ （我知道很多都是一样的。）

解决方案

关于如何抑制警告（scally够）的帖子，但我只是遇到了这个评论，它有这个可爱的标志（一些不太相关）：

  -g -O -Wall -Weffc ++ -pedantic \ 
 -pedantic-errors -Wextra -Waggregate-return -Wcast-align \ 
 -Wcast-qual -Wconversion \ 
 -Wdisabled-optimization \ 
 -Werror -Wfloat-等于-Wformat = 2 \ 
 -Wformat-nonliteral -Wformat-security \ 
 -Wformat-y2k \ 
 -Wimplicit -Wimport -Winit-self -Winline \ 
 -Winvalid-pch \ 
 -Wlong-long \ 
 -Wmissing-field-initializers -Wmissing-format-attribute \ 
 -Wmissing-include-dirs -Wmissing-noreturn \\ \\ 
 -Wpacked -Wpadded -Wpointer-arith \ 
 -Wredundant-decls \ 
 -Wshadow -Wstack-protector \ 
 -Wstrict-aliasing = 2 -Wswitch-默认\ 
 -Wswitch-enum \ 
 -Wunreachable-code -Wunused \ 
 -Wunused-parameter \ 
 -Wvariadic-macros \ 
  - Wwrite-strings 
  

所以，我认为这是一个很好的起点。没有意识到这是一个欺骗，但至少它被深埋。 ： - ）

Often in C under gcc, I will start with the following set of warning flags (painfully assembled from multiple sources):

-Wall -Wextra -Wformat-nonliteral -Wcast-align -Wpointer-arith -Wbad-function-cast \
-Wmissing-prototypes -Wstrict-prototypes -Wmissing-declarations -Winline -Wundef \
-Wnested-externs -Wcast-qual -Wshadow -Wwrite-strings -Wno-unused-parameter \
-Wfloat-equal -pedantic -ansi

I will build (at least my debug versions) with this set of warnings and fix everything I possibly can (usually everything), and then only remove flags if they are either not relevant or not fixable (almost never the case). Sometimes, I'll also add -Werror if I have to step away while compiling.

I'm just picking up C++ (yes, I'm 15 years behind the times), and I'd like to start off on the right foot.

My question is: Does someone have a precompiled similar set of complete warning flags for C++ under g++? (I know many of them will be the same.)

解决方案

D'oh, all of my original searches turned up 99% of posts on how to suppress warnings (scarily enough), but I just ran across this comment, which has this lovely set of flags (some less relevant):

Cross checked with:

http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html

-g -O -Wall -Weffc++ -pedantic  \
-pedantic-errors -Wextra -Waggregate-return -Wcast-align \
-Wcast-qual -Wconversion \
-Wdisabled-optimization \
-Werror -Wfloat-equal -Wformat=2 \
-Wformat-nonliteral -Wformat-security  \
-Wformat-y2k \
-Wimplicit  -Wimport  -Winit-self  -Winline \
-Winvalid-pch   \
-Wlong-long \
-Wmissing-field-initializers -Wmissing-format-attribute   \
-Wmissing-include-dirs -Wmissing-noreturn \
-Wpacked  -Wpadded -Wpointer-arith \
-Wredundant-decls \
-Wshadow -Wstack-protector \
-Wstrict-aliasing=2 -Wswitch-default \
-Wswitch-enum \
-Wunreachable-code -Wunused \
-Wunused-parameter \
-Wvariadic-macros \
-Wwrite-strings

So, I think that's a good starting point. Didn't realize this was a dupe, but at least it was deeply buried. :-)
