Is this a bug or UFU?

[George R Goffe]

Howdy,

I'm building gcc (and gmp/mpfr/mpc) from the repository and am having trouble. Could you take a peek and let me know what I'm doing wrong please?

Best regards and BE SAFE!

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
https://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.

Stop right there. Don't do that.

Read https://gcc.gnu.org/wiki/InstallingGCC instead, and do what it says.
