Thanks Jonathan for your help!
It now compiles without problems.
However, when I run make -k check it get stuck for several hours at:
Running
/home/hector/dwnld_prog/gcc-7.1.0/gcc/testsuite/gcc.dg/tree-ssa/tree-ssa.exp
...
Running
/home/hector/dwnld_prog/gcc-7.1.0/gcc/testsuite/gcc.dg/tsan/tsan.exp ...
WARNING: program timed out.
When I manually stop the program I get this summary:
got a INT signal, interrupted by user
=== gcc Summary ===
# of expected passes 105253
# of unexpected failures 311
# of unexpected successes 22
# of expected failures 199
# of unresolved testcases 2
# of unsupported tests 1611
What could be causing this problem?
Thanks for your help,
Hector

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/
Where GMP, MPC and MPFR compiled for the same hardware as you are
building on? One possibility is that they were compiled for a newer
x86 processor, and so use instructions that are not supported by the
machine you're building on.
You would avoid that kind of problem by not installing those libs
separately. See https://gcc.gnu.org/wikiInstallingGCC for how to make
it much easier.
