c++11 - c++11 std::unique_ptr 错误 cmake 3.11.3 bootstrap
问题描述
我正在尝试在 Ubuntu 16.04.4 LTS xenial 上引导 cmake 3.11.3。
我已经升级了我的 gnu g++ 编译器,如下所示:
> $ g++ --version

并手动重新指向符号链接:
$ ll /usr/bin/*g++*

-rwxr-xr-x 1 root root 1071984 Jun 6 04:26 /usr/bin/x86_64-linux-gnu-g++-8*
但是,我在 cmake 的配置中收到以下错误:
$ sudo ./bootstrap

知道为什么我会收到std::unique_ptr
不符合 c++11 的错误吗?
解决方案
就我而言,问题是因为我拥有 CMake 源代码的文件夹位于挂载目录中(实际上我的整个 rootfs 都挂载在 NFS 上)所以,我查看了“挂载”命令输出并选择了“/run/user” /1000' 位置作为本地位置,因为它是使用 tmpfs 安装的,并将我的 CMake 源代码移动到该位置。有了这个, ./bootstrap && make && sudo make install 成功执行。
