Re: UINT32_C' & 'UINT64_C': identifier not found error in Qt6.3.0 MSVC2019 64-bit

I managed to fix the problem using the advice of @c-toyama. But after that I got a build error.
LNK1181: the input file cannot be opened "release\Camera Image Wrapper.obj"

What could be the matter? Thank u

The file does not exist.
The file does exist but the spaces in the file name are a problem.

@ChrisW67 There are no spaces in the console, I do not know why it was copied like that. In the folder with the build, only ".i" files are generated, there is no .obj, apparently the error occurs before they are created. But if I disable QZXing.pri, everything builds well.

ChrisW67

@xlartas So you have not removed the temporary QMAKE_CXXFLAGS += -P made to debug the problem in the post you linked. The /P option suppresses compilation. It does not produce an .obj file....

@ChrisW67 What should I do then? I'm a python backend developer and I don't know much about C++. If I delete QMAKE_CXXFLAGS += -P, then I will start having errors like in that topic.

@ChrisW67 Its's my .pro

QT += core gui widgets concurrent network
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
CONFIG += c++17

include(QZXing/QZXing.pri)
QMAKE_CXXFLAGS += -P

SOURCES += \
    main.cpp \
    scanner.cpp

HEADERS += \
    scanner.h

FORMS += \
    scanner.ui

qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

@xlartas I have solved the problem. Just don't use QZXing with 6.3.2MSVC Static build qmake. Use a regular zxing-cpp built using the visual studio dev console.

cmake -S zxing-cpp -B zxing-cpp.release -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DCMAKE_MSVC_RUNTIME_LIBRARY=MultiThreaded -DCMAKE_CXX_STANDARD=17 -A x64

zxing-cpp.release -> rename -> zxing | and move to project folder

Connect the library to the .pro file

win32: LIBS += -L$$PWD/zxing/core/Release/ -lZXing
INCLUDEPATH += G:/zxing-cpp/core/src
DEPENDPATH += G:/zxing-cpp/core/src
win32:!win32-g++: PRE_TARGETDEPS += $$PWD/zxing/core/Release/ZXing.lib
else:win32-g++: PRE_TARGETDEPS += $$PWD/zxing/core/Release/libZXing.a

Make an include. Please note that the order of imports is sometimes important.

#include "ReadBarcode.h"
#include <ImageView.h>
#include <BarcodeFormat.h>
... and others if you need
