如何忽略包含的第三方库上的“-W”消息？-解网

问：

我经常在我的 C++ 项目中包含外部/第三方库，几乎每次它们在编译代码时都包含 -W 警告消息。

它们位于文件夹上。特别是在 Makefile 上，这就是我所包含的内容：lib/*

# Add .h and .hpp to the preprocessor build
HEADERS += $(wildcard lib/*.h)
HEADERS += $(wildcard lib/*.hpp)
HEADERS += $(wildcard lib/**/*.h)
HEADERS += $(wildcard lib/**/*.hpp)
HEADERS += $(wildcard lib/**/**/*.h)
HEADERS += $(wildcard lib/**/**/*.hpp)
HEADERS += $(wildcard src/*.h)
HEADERS += $(wildcard src/*.hpp)
HEADERS += $(wildcard src/**/*.h)
HEADERS += $(wildcard src/**/*.hpp)

# Add .c and .cpp files to the build
SOURCES += $(wildcard lib/*.c)
SOURCES += $(wildcard lib/*.cpp)
SOURCES += $(wildcard lib/**/*.c)
SOURCES += $(wildcard lib/**/*.cpp)
SOURCES += $(wildcard lib/**/**/*.c)
SOURCES += $(wildcard lib/**/**/*.cpp)
SOURCES += $(wildcard src/*.c)
SOURCES += $(wildcard src/*.cpp)
SOURCES += $(wildcard src/**/*.c)
SOURCES += $(wildcard src/**/*.cpp)

# FLAGS will be passed to both the C and C++ compiler
FLAGS +=
CFLAGS +=
CXXFLAGS += $(sort $(foreach HEADERS, $(HEADERS), -I$(dir $(HEADERS))))

是否可以指定（我在 Windows 上使用 MingGW，所以“gcc”）对于该文件夹，忽略警告消息？保持我的代码/编译干净？它与其他库非常无聊的“混乱”警告为什么要编译和检查状态。lib/*

C++ GCC Makefile mingw 警告

# Your sources and headers
SRC_HEADERS := $(wildcard src/*.h) $(wildcard src/*.hpp) $(wildcard src/**/*.h) $(wildcard src/**/*.hpp)
SRC_SOURCES := $(wildcard src/*.c) $(wildcard src/*.cpp) $(wildcard src/**/*.c) $(wildcard src/**/*.cpp)

# Third-party libraries' sources and headers
LIB_HEADERS := $(wildcard lib/*.h) $(wildcard lib/*.hpp) $(wildcard lib/**/*.h) $(wildcard lib/**/*.hpp) $(wildcard lib/**/**/*.h) $(wildcard lib/**/**/*.hpp)
LIB_SOURCES := $(wildcard lib/*.c) $(wildcard lib/*.cpp) $(wildcard lib/**/*.c) $(wildcard lib/**/*.cpp) $(wildcard lib/**/**/*.c) $(wildcard lib/**/**/*.cpp)

# FLAGS for your sources
SRC_FLAGS := 
SRC_CFLAGS :=
SRC_CXXFLAGS := $(sort $(foreach HEADERS, $(SRC_HEADERS), -I$(dir $(SRC_HEADERS))))

# FLAGS for third-party libraries (suppress all warnings using -w)
LIB_FLAGS := -w
LIB_CFLAGS := -w
LIB_CXXFLAGS := $(sort $(foreach HEADERS, $(LIB_HEADERS), -I$(dir $(LIB_HEADERS))))

# Targets and rules
...

# Rule for compiling your sources
%.o: %.cpp
    $(CXX) $(SRC_FLAGS) $(SRC_CXXFLAGS) -o $@ -c $<

# Rule for compiling third-party libraries
lib/%.o: lib/%.cpp
    $(CXX) $(LIB_FLAGS) $(LIB_CXXFLAGS) -o $@ -c $<

注意将禁止显示所有警告。如果要有选择地禁用特定警告，可以使用特定标志，例如 .-w-Wno-<specific-warning>

对于源中包含的库头文件，事情有点棘手。

一种方法可能是使用 s 来禁用包含标头的警告。#pragma

例如

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wall"
#pragma GCC diagnostic ignored "-Wextra"
#include "lib/whatever.hpp"
#pragma GCC diagnostic pop

这可能有点乏味，但希望比解决包含的标题中的每个单独警告不那么乏味 =）
