交叉编译无法找到crt1.o

Question

嗨我正在从Scratch(www.linuxfromscratch.org)编译Linux,我正在迈出一步,需要我编译一个测试c程序,看看编译是否正常工作并且失败了.
我使用的命令是:

echo "main(){}" > dummy.c
$LFS_TGT-gcc -B/tools/lib dummy.c
readelf -l a.out | grep ': /tools'

运行第二行时,编译器返回以下内容

..path../bin/ld: cannot find crt1.o: No such file or directory
..path../bin/ld: cannot find crti.o: No such file or directory
..path../bin/ld: cannot find -lc
..path../bin/ld: cannot find crtn.o: No such file or directory
collect2: ld returned 1 exit status

不知道这里有什么问题以及如何解决它,
到目前为止我已经重新安装了gcc软件包以及specs文件.

输出$LFS_TGT-gcc -v -B/tools/lib dummy.c是:

我意识到这是超长的,但如果有人告诉我相关的是什么,我会修剪它.因为老实说,我不知道什么是有用的.

Answer 1

crt1.o,crti.o和crtn.o以及libc.a都伴随着你的glibc.

您需要为目标系统编译glibc,并从/ tools/lib中查看它.

编辑:不一定是glibc,但无论你使用什么libc.
