在Gentoo上安装忍者有问题

Question

我正在尝试安装忍者(作为YouCompleteMe的先决条件)，我得到了错误。这是我的=dev-util/ninja-1.8.2::gentoo的总结

UPDATE 2:我的GCC：[1] x86_64-pc-linux-gnu-7.3.0 *版本

Answer 1

观测1

为什么要将迁移树存储在主目录中？？别担心，在写完观察2之后，我明白了原因。看到这让我很害怕。默认位置应该是：/usr/portage。该位置在创建本地覆盖(usr/local/portage将本地树与同步树区分开来)(即带有自定义版本号的包，或主迁移树中不存在的包)时有所帮助。人们普遍认为，Gentoo系统上的树和/或覆盖是系统组件，因此应该位于系统目录中。端口特性由驻留在/etc/portage中的文件控制。见Gentoo Por蒂奇Wiki。您的主目录应该用于您下载或创建的内容。这在系统和用户之间创建了一个边界。That边界是任何*NIX系统的基础。

观测2

虽然您的GCC编译器目前不稳定，但这并不是问题的原因。见Gentoo软件包- sys-devel/gcc。问题是/glibc的版本。波蒂奇相信你有2.25-r11版本，但是你的主机系统(因此也是观察1的原因。我相信你的安装在运行另一个linux版本或发行版的系统中)包含并链接到3.4.20版本。波蒂奇从主机收集链接信息，因为它认为您的主机系统是它自己安装的系统，作为一个正在运行的系统。请参阅意见1。

见单个主机上的多个glibc库。简而言之，你有几个选择：

1. 使用问题I链接中描述的方法1将端口指向正确的环境变量，或
2. 从您的主目录中删除您的安装，遵循手册(arch是无关的)，省略设置引导加载器一章，同时完成安装。始终使用chroot命令输入环境。在chroot中创建一个用户，并在每次输入chroot时使用su user。Tip:创建/home/username/mnt/gentoo

然后使用Gentoo手册:着色中概述的Chrooting过程，将chroot指向/home/username/mnt/gentoo。在色度之后，观测到1's边界。这将欺骗portage，使人相信它是安装在它自己的主机上的，因为它尊重chroot环境。

1. 使用这个脚本：安装与现有系统并行的GNU libc版本，可以简化选项1，但是如果您与其他用户共享主机，我会建议您不要这样做，因为如果您将--prefix选项设置为主目录中的某个位置，然后与其他用户共享程序，它将不会运行。
