尝试构建库时出错

Question

我试图根据https://chromium.googlesource.com/breakpad/breakpad/的文档构建breakpad库，但是当我执行./configure && make, 时检查C++ 11时出现错误，即使我目前能够编译与C++ 11。

这里是从./configure输出：

这里是从g++ --version输出：

，这里是一个示例应用程序用C++ 11编译：

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 ++没有支持对于c + + 11，或者如果有一种方法，我可以重写或添加额外的参数，以便它正确地检测我的编译器。

任何有关我可能会错过或做错的提示？ breakpad是否使用可能安装在我的系统中的另一个gcc？

Answer 1

虽然GCC 4.7确实有一些C++ 11吨的能力，这是严重缺乏的大部分所需的所有功能。因此，虽然配置脚本使用正确的选项来启用C++ 11，但编译器实际上无法处理测试程序，因为它使用的是旧版GCC 4.7版中不具备的功能。

如果您想使用Breakpad，您需要支持旧编译器的旧版Breakpad，或者您需要将编译器更新为更新的版本。 5系列应该完全支持C++ 11。
