Hello gcc community!
I'm trying to compile gcc 7.1.0 from source. I used gcc 5.1.0 and gcc
6.1.0 and got the same error. these are the steps I'm doing:
tar -zxvf gcc-7.1.0.tar.gz
mkdir gcc_obj
cd gcc_obj/
CC=gcc6 CXX=g++6 ../gcc-7.1.0/configure
--prefix=$HOME/installed/gcc-7.1/ --enable-languages=c,c++,fortran
--program-suffix=7 --with-gmp=$HOME/installed/
--with-mpc=$HOME/installed/ --with-mpfr=$HOME/installed/
however, I got an illegal instruction error. Here is the output:
/bin/sh ./libtool --tag=CC --mode=compile
