前段时间我开始了“Linux from Scratch”项目。首先,我从 Ubuntu 15.10 64bit 开始,并根据 PDF 文件进行所有操作。通过第 5.7.2 段中的检查,它没有工作。之后我重新开始,使用 CentOS 7.2,但它既不工作。在这两次尝试中,我在编译和安装以前的软件包时都没有出错。
输入:
echo 'int main(){}' > dummy.c
$LFS_TGT-gcc dummy.c
输出:
/mnt/lfs/tools/bin/../lib/gcc/x86_64-lfs-linux-gnu/5.3.0/../../../../x86_64-lfs-linux-gnu/bin/ld: cannot find crt1.o: No such file or directory

collect2: error: ld returned 1 exit status
输入:
readelf -l a.out | grep ': /tools'
输出:
readelf: Error: 'a.out': No such file
我发现没有适用于 StackOverFlow 或不同平台的解决方案。
