Qtcreator+cmake compiler settings

One 、 background

Recently in contact with Qt Complete the verification of the cross platform scheme , In the use of Qt The compiler is , Discovery available CMake Carry out engineering construction , Unfortunately, it can't run anyway . Finally, through exploration , At last I found the reason , Organize them into articles , I hope it helps others .

Two 、 Wrong type

error 1

	CMake Error: Generator: execution of make failed. Make command was: jom /nologo cmTC_28787\fast 

error 2

CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM 

error 3

 The system cannot find the specified file  （ansi code ）
    perhaps 
 The system cannot find the specified file  （utf8 code ）

3、 ... and 、 Problem explanation

problem 1 : cmake In execution make Command failed ;
problem 2：cmake No build tools found Ninja The execution directory of , Need to set up CMAKE_MAKE_PROGRAM
problem 3： The system cannot find that the specified file has , Some compilers will output utf8 Coded garbled

Four 、QtCreator Next use CMake Specific configuration of

1 . establish QtWidget project ：

2. Select build system as CMake

3. Select compiler type as vs2015
   

4. After creation , The system directly reports an error

5. Problem analysis
   QtCreator Use CMake Build , The default compiler used is mingw and nmake Build system , For specific use, please refer to others blog.
   So msvc compiler ,qtCeator Our support is not good enough , But it's not useless , You need to be familiar with qtCreator, Modify the order by yourself
6. resolvent
   stay qtCreator Of manag kits Click the button in , Select... In the pop-up dialog box vs2015_x64, modify CMake Generator by visual studio 14 2015 x64
   
   compile , Still reporting a mistake , Need to continue to modify . Click item -> Build settings panel , Delete In configuration item ：

	-GNMake Makefiles JOM

Delete all the settings in the four configuration items , Remember to clean it all , And then execute it again cmake structure , You can build success , But you can't compile code , Generate executable files .
It still needs to be changed , Open the project ->buil&run , Find the configuration ：Build Steps for , take all Option to remove , Check ALL_BUILD You can compile the executable .

5、 ... and 、 Postscript

QtCreator Yes msvc The support is not complete , Many holes , Recommended or used Mingw To create cmake, No settings , It can be used directly .
