使用make命令编译c++11

Question

我试图使用MobaXterm终端在CPU上编译我的代码，我使用make命令编译我的代码。但是很多错误都是从下面这些开始的。我在网上搜索并了解到这是编译器的问题。但我用的是make，而不是g++。对于解决这些编译问题有什么建议吗?

Answer 1

经过多次尝试和建议，我终于找到了解决方案:

编辑我的Makefile如下:

# Compilation flags
ifeq ($(DEBUG),1)
CXXFLAGS += -g -std=c++11
else
CXXFLAGS += -O2 -std=c++11
endif

Answer 2

这更多是编译器的问题，而不是make的问题。

1. 检查编译器是否正确设置为您所在的系统。
此外，如果编译器设置良好，检查它是否兼容编译c++ 11标准，因为旧的编译器可能是问题。

我认为如果你:-包括你的操作系统你在用什么编译器

请告诉我这是否有用。
