Error 1 and 2 while make Process in gcc Pass 1

[BeanMe]

!!Note: I am using version 6.8 of the LFS book!! If I compile GCC (make command), the following Error occours:

(...) checking for gmp.h... no configure: error: gmp.h can't be found, or is unusable make[2]: * [configure-stage1-mpfr] Error 1 make[2]: Leaving directory `/mnt/lfs/sources/build-gcc' make[1]: * [stage1-bubble] Error 2 make[1]: Leaving directory `/mnt/lfs/sources/build-gcc' make: * [all] Error 2

I think the error is in the first line. I have done as written in the book... Can you help me?

Use the lfs-support mailing list for these types of errors.
