Description Fedja Beader 2021-04-18 15:20:45 UTC

GNAT is required to build GNAT. sys-devel/gcc ebuild does not pull in a bootstrap and therefore it will not build.

Reproducible: Always

Steps to Reproduce:
printf -- '-ada\n' >> /etc/portage/use.mask
USE=ada emerge -a1v gcc
Actual Results:  
...
checking for objdir... .libs
checking for the correct version of gmp.h... yes
checking for the correct version of mpfr.h... yes
checking for the correct version of mpc.h... yes
checking for the correct version of the gmp/mpfr/mpc libraries... yes
configure: error: GNAT is required to build ada
 * ERROR: sys-devel/gcc-10.2.0-r5::gentoo failed (configure phase):
 *   failed to run configure
...


Expected Results:  
Working GNAT
