Preface

Download... On the Internet Qt In the project, in the machine , Using one's own QtCreator We often encounter various errors
“QMAKE_CXXFLAGS+=–target=i686-w64-mingw32” “QMAKE_LFLAGS+=–target=i686-w64-mingw32”

One 、 Error reason

I have summarized the following three reasons ：
1. The original project is to use MinGW32/64 Generated by the compiler
2. The original project is to use MSVC2015~msvc2019 Generated by the compiler
3. Use of original project lang Generated by the compiler
among clang The compiler may be unfamiliar to some of its partners
Clang The compiler is composed of APPLE The company's compiler Daniel Chris Lattner Prepared under the leadership of , The goal is to replace the famous GCC compiler ; from XCODE4 Start , That is to say Mac OS X 10.6 Version on the system ,Apple Announce the end of the update GCC compiler , such GCC Stay at GCC4.2 edition , And suggest you use LLVM Compiler 2.0（LLVM-Clang）, This version fully supports C++/ Objective-C++, And provide libc++ Library to support new C++ standard（C++0x standard ）, and GCC/LLVM-GCC Support is GCC Standard library libstdc++;
in addition , because LLVM-Clang Excellent design ,Android NDK from r11 I suggest you switch to clang. And the GCC Marked as deprecated( Abandoning ), take GCC Version locked in GCC 4.9 No more updates ;Android NDK from r13 rise , By default Clang Compile . But I haven't put GCC Delete ,Google consider libc++（LLVM-Clang Of c++ Standard library ） Not stable enough ; Android NDK stay r17 They declared that they would no longer support GCC And in the following r18 Delete GCC. Now? GCC The main battlefield is only Linux Heel part Windows Application software development .

Two 、 terms of settlement

1. First, we are installing Qt When , Remember to check msvc,MinGW These compilers , Because I am in windows Lower development , All only selected msvc,MinGW compiler

2.QtCreator To configure

Configure the corresponding msvc perhaps MinGW compiler
