我正在尝试在一台计算机上安装 Gentoo amd64惠普 DL380 G4。我已经成功到达配置Linux内核Gentoo 安装手册中的部分。使用此命令后：
emerge --ask sys-kernel/gentoo-sources
我得到以下输出：
(chroot) livecd / # emerge --ask sys-kernel/gentoo-sources
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild N ] sys-devel/bc-1.06.95-r2 USE="readline -libedit -static"
[ebuild N ] sys-kernel/gentoo-sources-4.14.65 USE="-build -experimental -symlink"
Would you like to merge these packages? [Yes/No] yes

问题可能是什么？
答案1
相关行是这样的：
checking for C compiler default output file name... configure: error: C compiler cannot create executables
这意味着当检查包configure的脚本bc（内核构建过程所需的）以确保按照指定的方式调用 C 编译器 (GCC) 时，它会失败。造成这种情况的可能原因包括但不限于：
- 无效选项（在 Gentoo 上将位于
CFLAGS中的变量中/etc/portage/make.conf）。这是最有可能的情况。示例包括将-fstack-protector选项传递给较旧的 GCC 版本、尝试在错误类型的系统上构建 32 或 64 位代码，或者在构建没有 Graphite 支持的 GCC 时尝试使用 Graphite 优化选项。 - 硬件问题（RAM 故障、PSU 故障、CPU 故障等）。
- 磁盘上的静默数据损坏。
- 内存不足（除非您已经配置了内置内容，否则不太可能）
tmpfs和你没有太多内存）。
