emscripten.h: No such file or directory

[8Observer8]

Hello,

I have Qt WebAssembly and emsdk installed. How to solve it?

I added INCLUDEPATH:

QT  += core gui widgets

INCLUDEPATH += "C:\emsdk\upstream\emscripten\system\include"

CONFIG += c++17

SOURCES += \
    main.cpp

This directory has two emscripten.h. Here:

And here:

But it doesn't work too: "Including files directly from the emscripten source tree is not supported. Please use the cache/sysroot/include directory"

C:\emsdk\upstream\emscripten\system\include\emscripten\version.h:8: error: #error "Including files directly from the emscripten source tree is not supported.  Please use the cache/sysroot/include directory".
In file included from C:/emsdk/upstream/emscripten/system/include/emscripten/emscripten.h:29,
                 from ..\..\main.cpp:5:
C:/emsdk/upstream/emscripten/system/include/emscripten/version.h:8:2: error: #error "Including files directly from the emscripten source tree is not supported.  Please use the cache/sysroot/include directory".
    8 | #error "Including files directly from the emscripten source tree is not supported.  Please use the cache/sysroot/include directory".
      |  ^~~~~

Solution is to add the following INCLUDEPATH:

QT  += core gui widgets

INCLUDEPATH += "C:\emsdk\upstream\emscripten\cache\sysroot\include"

CONFIG += c++17

SOURCES += \
    main.cpp

To avoid conflicting declaration do not compile for Desktop. Compile for WebAssembly.

I have tried to include cache/sysroot/include directory as in the message above:

QT  += core gui widgets

INCLUDEPATH += "C:\emsdk\upstream\emscripten\cache\sysroot\include"

CONFIG += c++17

SOURCES += \
    main.cpp

But I have this error: conflicting declaration 'typedef struct div_t div_t' 64 | typedef struct { int quot, rem; } div_t;
