I get an error during the configuration phase (./configure)
checking for sufficient C++ language/library level... no
configure: error: This libpqxx version needs at least C++17
I have installed devtoolset-9 and created some aliases
alias g++="g++ -std=c++17"
alias cpp="cpp -std=c++17" and so on.
g++ version
g++ (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
How can I solve the problem?
