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.
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.
