Compilation error in Qt MSVC 2019 64Bit environment

Nan Feng

Hi, dear Qt development team, I want to use the Qt static library to compile, so I downloaded the source code to compile, compiled in MSVC 2019 32 Bit, everything is normal, and got the compiled static library, but it is compiled with MSVC 2019 64 Bit I encountered some errors and warnings. May I ask what caused the problem? How should I solve it?
Please refer to the screenshot for error details. Looking forward to your reply.! alt text

@Nan-Feng Please post FIRST errors as text, not screen shot. And please translate the error messages into English.

I don't understand how you are expecting to compile/work if you are mixing 32- & 64-bit libraries? Use only one or the other.

Nan Feng

My computer is windows 64, ""I just want to compile the 64-bit Qt static library"". As for the reason for the error just now, the following is my operation. I searched on the Internet and said that I want to compile 64-bit MSVC and use x64 Native Tools Command Prompt for VS 2019 This, then switch to the source directory and enter the command in the reply to compile it. So how should I compile the 64-bit MSVC 2019 Qt static library? Please give pointers

JonB

@Nan-Feng
I'm afraid I don't know the exact answers, maybe someone else will tell you. But if you want to do 64-bit only, I assume do not do your current:

so I downloaded the source code to compile, compiled in MSVC 2019 32 Bit

-platform win32-msvc

Nan Feng

In addition, I used two different compilation commands, the difference is not very big, but the compiled things are very different, one is that the .pdb file is generated for each file while generating the .exe in the bin directory, the other There is only one .pdb file in the bin directory compiled by the command. . . . What does the .pdb file do? Will it affect me if I delete him?
The two compilation commands are as follows:
configure.bat -static -prefix "D:\Environment\QtStaticLib\MSVC-2019-32Bit" -confirm-license -opensource -debug-and-release -platform win32-msvc -nomake examples -nomake tests -plugin-sql-sqlite -plugin-sql-odbc -qt-zlib -qt-libpng -qt-libjpeg -opengl desktop -mp

The following command generates a .exe in the bin directory with a .pdb with the same name
configure -confirm-license -opensource -platform win32-msvc -debug-and-release -static -static-runtime -force-debug-info -opengl dynamic -prefix "D:\Environment\QtStaticLib\MSVC-2019-32Bit"- qt-sqlite -qt-pcre -qt-zlib -qt-libpng -qt-libjpeg -opengl desktop -qt-freetype -nomake tests -no-compile-examples -nomake examples

What does the .pdb file do?

It contains debug information and is only needed if you want to debug that stuff.
Your actual issue seems to be that you are mixing 32bit and 64bit binaries as @JonB said and this can't work.

Nan Feng

Then I just want to compile 64 Bit MSVC 2019, how should I do it?
By the way, when Qt Creator uses the compiled static library, it will prompt that qmlscene is not installed. What is the situation? So I copied the file in the dynamic library to the path of the static library, and no longer prompted. Will this have any bad effects?

Your Qt build picks up clang in D:\Environment\LLVM\lib\libclang , which is not compatible with the compiler you've choosen. So unless you need to build documentation via qdoc, just avoid this dependency. You most likely have set LLVM_INSTALL_DIR environment variable to point to the LLVM in D:\Environment\LLVM? Just unset it.

qmlscene is a small tool to preview .qml files without any C++ entry point (main.cpp). If you don't know it, you probably don't need it :)

Hello, I canceled the environment variables of LLVM, and re-extracted the source code and compiled it, but some errors occurred in the compilation.

See QTBUG-88625 for your the error and fixes in the comment.

What is the difference between the three options compilation in QtCreator? I don't quite understand.
-release means that debug mode cannot be used in QtCreator?

-release
-debug
-debug-and-release
