配置错误“需要支持C++11语言功能的编译器。”

Question

我试图基于https://chromium.googlesource.com/breakpad/breakpad/的文档构建breakpad库，但当我执行./configure && make时，检查c++11时出现错误，尽管我目前可以使用c++11进行编译。

以下是./configure的输出

以下是g++ --version的输出

下面是一个使用c++11编译的示例应用程序：

g++ -std=c++11 -g -c -pedantic -Wall -Wextra -I../boost_1_57_0 -L../boost_1_57_0/stage/lib UtilsText.cpp -o UtilsText.o
g++ -std=c++11 -g -c -pedantic -Wall -Wextra -I../boost_1_57_0 -L../boost_1_57_0/stage/lib UtilsWeb.cpp -o UtilsWeb.o
g++ -std=c++11 -g -c -pedantic -Wall -Wextra -I../boost_1_57_0 -L../boost_1_57_0/stage/lib WorkElement.cpp -o WorkElement.o

我不知道为什么breakpad抱怨我的g++不支持c++11，或者是否有一种方法可以覆盖或添加额外的参数，以便它正确地检测我的编译器。

有没有提示我可能遗漏了什么或做错了什么？breakpad使用的是另一个可能安装在我的系统中的gcc吗？

Answer 1

虽然GCC 4.7确实有一些C++11功能，但它严重缺乏所需的大多数功能。因此，尽管配置脚本使用了正确的选项来启用C++11，但编译器实际上不能处理测试程序，因为它使用了旧的GCC 4.7版本中没有的功能。

如果要使用Breakpad，则需要支持旧编译器的较旧版本的Breakpad，或者需要将编译器更新到较新版本。5系列应该完全支持C++11。

Answer 2

也许你需要这个，为我工作

yum install gcc-c++

Answer 3

对于Fedora使用：

sudo dnf install gcc-c++
