Ubuntu 18.04 What i have to do?

Use a newer compiler, as per https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md.

I assume you're using the GCC shipped with Ubuntu Bionic, which is GCC 7. As of #23060, that is not new enough to build master, GCC 8.1+ is required. You can apt install gcc-8 and use that.

clang-10 should also work: https://packages.ubuntu.com/bionic/clang-10

Now i have installed: /usr/local/src/wallets/bitcoin# gcc

But /usr/local/src/wallets/bitcoin# gcc --version

I have installed clang 6.0, 9 and 10. What i have to do to switch compiler to 10. Which configure option i have to switch? I have been compiling bitcoind for many years with such options on Ubuntu 16.04. CFLAGS="-Ofast -march=native -mtune=native -pipe -fPIE" CXXFLAGS="-Ofast -march=native -mtune=native -pipe -fPIE" LDFLAGS="-Ofast -march=native -mtune=native -pipe -fPIE" ./configure --without-miniupnpc --with-incompatible-bdb --without-gui --disable-tests

Thank you for attention.

For example:

$ ./configure CC=gcc-9 CXX=g++-9
$ make

update-alternatives might be handy

Unfortunately CC="gcc-9" CXX="g++-9 -stdlib=libc++ -std=c++17" CFLAGS="-Ofast -march=native -mtune=native -pipe -fPIE" CXXFLAGS="-Ofast -march=native -mtune=native -pipe -fPIE" LDFLAGS="-Ofast -march=native -mtune=native -pipe -fPIE" ./configure --without-miniupnpc --with-incompatible-bdb --without-gui --disable-tests not works.

You can't set libc++ for g++.

Either:

CC="gcc-9" CXX="g++-9", or CC="clang-10" CXX="clang++-10 -stdlib=libc++"

CC="gcc-9" CXX="g++-9" It's help to continue compiling. Happy end. Thank you for attention and for help!
