I am using LFS 7.3. following the instructions given on pages 37-8 for first time GCC compilation. I get the following error:
checking for objdir... .libs checking for the correct version of gmp.h... no configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+. Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify their locations. Source code for these libraries can be found at their respective hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/. See also http://gcc.gnu.org/install/prerequisites.html for additional info. If you obtained GMP, MPFR and/or MPC from a vendor distribution package, make sure that you have installed both the libraries and the header files. They may be located in separate packages. The error message isn't a huge surprise because I don't see GMP mentioned in the instructions. That is, I have unpacked GMP, MPFR, and MPC but the command line given on page 38 of the book is this: ../gcc-4.7.2/configure\ --target=$LFS_TGT\ --prefix=/tools\ --with-sysroot=$LFS \--with-newlib \--without-headers \--with-local-prefix=/tools \ --with-native-system-header-dir=/tools/include \ --disable-nls \--disable-shared \--disable-multilib \--disable-decimal-float \--disable-threads \--disable-libmudflap \--disable-libssp \--disable-libgomp \--disable-libquadmath \--enable-languages=c \--with-mpfr-include=$(pwd)/../gcc-4.7.2/mpfr/src \ --with-mpfr-lib=$(pwd)/mpfr/src/.libs THere is no mention of GMP or MPC on the command line. Is this a mistake in the text? What am I doing wrong?
