charconv file not found

[Izza]

Hello
I am working on qt 5.12.2 for web assembly
its windows 10 bash
emcc doesnt seem to support charconv
it says file not found.

Hi,

What configure options did you found in this ?

Ok
I have a confusion regarding charconv that whether or not is being fully supported by clang,llvm + emcc
in short , in web assembly.

Secondly here are my configurations if you are talking about makefile:

CC = emcc
CXX = em++
DEFINES = -DQT_DEPRECATED_WARNINGS -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB
CFLAGS = -pipe -O3 -Wall -W $(DEFINES)
CXXFLAGS = -pipe -O3 -std=c++17

This guy also spoke about something regarding limitaions we have on clang :

Moreover , i am using emsdk 1.38.16
Note: I am sorry if i have provided les details. you can ask more.

Something is really not clear here: what exactly are you doing ?
Building an application of yours ?
Building that library standalone ?

Library for now

In that case, you should rather contact the library authors to get help building their library.
