I'm running Debian 9 on WSL 2 and I'm trying to compile C++ code that uses the <charconv> header. I have the line set(CMAKE_CXX_STANDARD 17) in my Cmake file so it's definitely using C++ 17 but when I compile it I get this error message
In file included from /mnt/d/blang/frontend/Token.cc:5:0:/mnt/d/blang/frontend/Token.h:11:20: fatal error: charconv: No such file or directory #include <charconv>I build GCC 12 from source and installed it. When I run gcc -v I get this.
Using built-in specs.COLLECT_GCC=gccCOLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-pc-linux-gnu/12.1.0/lto-wrapperTarget: x86_64-pc-linux-gnuConfigured with: ./configure --disable-multilibThread model: posixSupported LTO compression algorithms: zlibgcc version 12.1.0 (GCC) How do I fix this?
