Hello
I'm using MinGW installed on Windows 10 Pro via MSYS2.
g++ --version returns: 'g++.exe (Rev5, Built by MSYS2 project) 15.1.0'
gdb --version returns: 'GNU gdb (GDB) 16.3'
I'm learning C++23, and when I write:
#include <iostream>
#include <print>
int main() {
std::print("Hello, World!\n");
return 0;
}
In Code::Blocks 25.3, when I start the compilation I obtain:
Using experimental features requires linking with `-lstdc++exp`:https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dynamic_or_shared.html#manual.intro.using.linkage.experimental
It is possible to find the library which contains the function in question with grep: $ grep -Flr __write_to_terminal /ucrt64/lib/ /ucrt64/lib/libstdc++exp.a -- Best regards, LIU Hao
