LFS-7.2: mpfr-3.1.1, error: gmp.h can't be found, or is unusable.
 

I just tried to install my LFS-7.2 using scripts on my laptop. But I can't build mpfr-3.1.1 all I get is "error: gmp.h can't be found, or is unusable."

I don't understand why I get this error, I have built LFS-7.2 using the same scripts without problem in VirtualBox.

EDIT: Forgot to say that gmp.h is in /mnt/lfs/usr/include (that is /usr/include when in chroot) and a diff /usr/include/gmp.h /mnt/lfs/usr/include/gmp.h gives no difference. I'm running on my own LFS cd i built in VirtualBox using my LFS-7.2 I built in VirtualBox using the exact same scripts..

EDIT-2: I have now solved my problem, found a tiny bug in my adjusting-toolchain script so it was never adjusted.
