I understood the mutual relationship.
I found a way to change gmp ABI and make gcc work properly.
Steps to follow:
#1 ubuntu install
#2 apt-get gcc(gcc-9.3.0)
#3 gcc source install(for example gcc-10.1.0)
#3-1 gcc source download
#3-2 ./contrib/download_prerequisites(GMP,MPFR,MPC,.:download)
*#3-3 gmp ABI update(mpz struct change)
#3-4 configure,make,make install
#4 ABI update gmp install use new gcc
This bug was caused by incorrect use, and since the normality of normal use has
been confirmed, I will closed it.
Thanking you in advance.
