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.

This can also happen if `--with-lib-path=/tools/lib` is missing because ld won't know to add `-L/tools/lib` — , Jan 27 '14 at 18:47

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.

I already compiled glibc... but ill redo it to see if it helps. – Drew Galbraith Nov 01 '11 at 03:31
thanks for the help... turns out my problem was calling `make install` without sudo. A fresh install cleaned everything up. Thanks! 50 rep coming your way. – Drew Galbraith Nov 01 '11 at 03:58

If recompiling gcc is not an option because it is already installed with sysroot, then try this:

`export CFLAGS="--sysroot=<your-gcc-sysroot>"`

(hint: libc.so.x is in <your-gcc-sysroot>/lib)

Then edit your makefile and replace any

`CFLAGS=BLA-BLA`
`CPPFLAGS=BLA-BLA`

with

CFLAGS+=BLA-BLA CPPFLAGS+=BLA-BLA

Pass -v to your $LFS_TGT-gcc to understand what is happening.

The -v flag will show you want programs gcc is running, in particular it will show how ld is invoked, so you'll understand what is wrong. – Basile Starynkevitch Oct 28 '11 at 21:19
I posted the verbose output of the command, I'm not sure what part is relevant so I posted it all. – Drew Galbraith Oct 30 '11 at 04:40

I was facing the following problem:

root@gccc# arm-wrs-linux-gnueabi-gcc x.c
/opt/tools/wrl3.GA/wrlinux-3.0/layers/wrll-toolchain-4.3-85/arm/toolchain/x86-linux2/bin/../lib/gcc/arm-wrs-linux-gnueabi/4.3.2/../../../../arm-wrs-linux-gnueabi/bin/ld: crt1.o: No such file: No such file or directory
collect2: ld returned 1 exit status
root@gccc#

So when I researched it I found out that I was not able to find out the sysroot in the correct path. So I specified the sysroot on the command line and my problem was solved:

root@gccc# arm-wrs-linux-gnueabi-gcc x.c --sysroot=/opt/tools/wrl3.GA/sysroot.2011_05_31.18_29_24/arm11_le-glibc_small/sysroot/ -o exe
