Cross Compile Cannot Find crt1.o

Question

Hi I am compiling Linux from Scratch (www.linuxfromscratch.org) and I am on a step that requires my to compile a test c program to see if the compilation is working and it is failing.
The commands I am using are:

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

When running the second line, the compiler returns the following

..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

Not sure what the problem is here and how to fix it,
So far I have reinstalled the gcc package as well as the specs file.

The output of $LFS_TGT-gcc -v -B/tools/lib dummy.c is:

I realize that it is super long but if someone would tell what is relevant I will trim it. Because quite honestly I don't know whats useful.

Answer 1

crt1.o, crti.o and crtn.o and libc.a all come with your glibc.

You need to have glibc compiled for your target system and installed, from the looks of it, in /tools/lib.

EDIT: Not necessarily glibc, but whatever libc you're using.
