Working on FreeBSD8.1, in a jailed environment. I have an ancient (gcc3.4.6) version of gcc that works as my C compiler. gmake version 3.8.1 I do the following, as root: > tar zxf gcc-4.7.1.tar.gz > cd gcc-4.7.1 > ls -atlG contrib/downl* > ./contrib/download_prerequisites <-- seems to work > ./contrib/download_ecj <-- seems to work > cd .. > mkdir obj_gcc471 > cd obj_gcc471 > ../gcc-4.7.1/configure <-- runs successfully. > gmake During the make process, I get the following error: checking for math/rint... yes checking for long double... yes checking format of `long double' floating point... IEEE extended, little endian checking for gmp.h... no configure: error: gmp.h can't be found, or is unusable. gmake[2]: *** [configure-stage1-mpfr] Error 1 gmake[2]: Leaving directory `/usr/src/local/obj_gcc471' gmake[1]: *** [stage1-bubble] Error 2 gmake[1]: Leaving directory `/usr/src/local/obj_gcc471' N.B., gmp.h is *not* present anywhere in gcc-4.7.1 after the download_prerequisites. Should it be? Any help is appreciated, Thanks. PB
