problems building it with 7zip in windows 11

[BadulakheMagiko]

when I use make or nmake it shows this:

        cd YACReader\ && ( if not exist Makefile C:\Qt\6.10.2\mingw_64\bin\qmake.exe -o Makefile ...\Downloads\yacreader-develop\YACReader\YACReader.pro "CONFIG+=7zip" ) && nmake -f Makefile
Project MESSAGE: Using pdfium.
Project ERROR: Could not find libpdfium.
NMAKE : fatal error U1077: 'cd' : return code '0x3'
Stop.

I have the needed files of 7zip as the guide indicates, including the dll in the dependencies folder, any guess?

On Windows I use QtCreator + Qt 6 for msvc2022 (I have Visual Studio 2022 Community installed with the c++ toolkit).

The problem is that in the mingw configuration path libpdifum can't be found.

CONFIG(pdfium) {
  message(Using pdfium.)
  DEFINES += "USE_PDFIUM"
  SOURCES += ../common/pdf_comic.cpp
  msvc {
      INCLUDEPATH += $$PWD/pdfium/win/public
      contains(QMAKE_TARGET.arch, x86_64): {
          LIBS += -L$$PWD/pdfium/win/x64 -lpdfium
      } else:contains(QMAKE_TARGET.arch, arm64): {
          LIBS += -L$$PWD/pdfium/win/arm64 -lpdfium
      } else {
          LIBS += -L$$PWD/pdfium/win/x86 -lpdfium
      }
  }
  unix|mingw {
    macx {
      LIBS += -L$$PWD/pdfium/macx/bin -lpdfium
      INCLUDEPATH += $$PWD/pdfium/macx/include
    }
    else:!contains(QT_CONFIG, no-pkg-config):packagesExist(libpdfium) {
      message(Using system provided installation of libpdfium found by pkg-config.)
      CONFIG += link_pkgconfig
      PKGCONFIG += libpdfium
    } else:exists(/usr/include/pdfium) {
      message(Using libpdfium found at /usr/lib/pdfium)
      INCLUDEPATH += /usr/include/pdfium
      LIBS += -lpdfium
    } else {
      error(Could not find libpdfium.)
    }
  }
}

The easiest fix would be to use the no_pdf flag to CONFIG in the qmake call "CONFIG+=no_pdf".

Thanks for the advice! But now it shows me this message when I do make:

compiling main.cpp
g++: fatal error: cannot specify '-o' with '-c', '-S' or '-E' with multiple files
compilation terminated.
make[2]: *** [Makefile.Release:11637: release/main.o] Error 1

Do you think this could be to because mingw?

[luisangelsm]

I don't use mingw myself, compatibility was added back in 2021 by a contributor: #279

But since then I haven't heard of anyone using it so it could be completely broken, specially for Qt6 development.

You can try figuring out what's going on or you can try using the environment I told you about before.
