Changing default compiler from clang to gnu gcc in termux

I want to set default compiler from clang to gcc in termux (android application).

gcc isn't available in official repo so I used pointless community repo. But now I can't configure the termux to use gcc instead of clang.usr/bin/ contain g++, gcc, gcc-8, g++8.But gcc --version command shows default clang.gcc-8 --version shows:

"CANNOT LINK EXECUTABLE "gcc-8" : library "libc++_shared.so" not found linker: CANNOT LINK EXECUTABLE "gcc-8": library "libc++_shared.so" not found.
