我尝试用"g++ -std=c++11 -o w w.cpp“编译下面的程序,得到错误”cc1plus: error: unrecognized command line option "-std=c++11“”。已尝试使用g++ -Dstd=c++11 -o w w.cpp进行编译,并获得以下错误集:

我最近下载了链接中提到的代码。我的GCC版本是4.1.2。在console中开始出现以下错误之前,编译过程至少进行了一个小时。
LLVM支持声明我需要使用gcc44-c++,这在我们的机器中是不可用的:

# yum install gcc44-c++

我按照github中的这些说明克隆并构建了boost库。
./b2命令的末尾告诉我
Boost C++库已成功构建!
The following directory should be added to compiler include paths:
/home/user/Desktop/boost
The following directory should be added to linker library paths:
/home/user/Desktop/boost/stage/lib
我应该如何处理这些文件夹?我想把boost放在“为了让gcc看到它而应该去
我在unique_ptr中间的const_iterator上使用std::rotate时遇到了问题。
我试过了:
std::vector<std::unique_ptr<Object> >::const_iterator middle;
// middle is pointing at somewhere within vec defined elsewhere.
std::rotate(vec.begin(), middle, vec.end());
这导致没有匹配的函数调用旋转(...iterator,...const_iterator &,...itera

我有增强程序选项版本1.78安装通过vcpkg。当我使用clang++和-std=c++20编译时,我会得到以下错误。当我用g++编译时,这种情况不会发生。根据这个,std::unary_function被废弃为C++11。

我有两个系统,一个是rhel4,另一个是rhel6。在编译过程中,我想相应地区分和编译。
我的方法:
在rhel5机中
-bash-4.1$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.5
在rhel4机中
-bash-3.00$ cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4
所以我想用这样的东西-
OSVERSION = cat /etc/redhat-release | cut -d "." -f 1 |
我正在尝试从 6.5上的源代码安装CentOS R3.1.1。
