I have finished the chapter 5 of the book.
And after I entered the chroot I realized that make is not working even though it is present.
root:/sources/linux-3.5.2# make mrproper
bash: /tools/bin/make: No such file or directory
ls -l /tools/bin/make
-rwxr-xr-x 1 root root 559139 Nov 13 11:19 /tools/bin/make
I read on LFS FAQ that is probably due to a bad interpreter (link)
so I did
readelf -l /tools/bin/make | grep interpreter
[Requesting program interpreter: /lib64/ld-linux-x86-64.so.2]
so it's wrong they said it should be /tools/lib64/ld-linux-x86-64.so.2
Is they a way to precise when building it the right interpreter ?
