need help in setting Build & Run option after importing an existing project

[ravi2k18]

hi,

I am importing an existing project downloaded from github. But I could not understand how to set build and run options for that as I have installed several versions of Qt hence Qt creator shows all the available tools in "Auto-detected" but how to make a particulate compiler and qmake active?

I want to use MSVC 2017 compiler and its qmake. Please see below in snaps.

Thanks...

Hi @ravi2k18,

Creator needs to auto-detect the Visual Studio C++ compiler - you cannot set them up manually.

• Did you install Visual C++ to the default path?
• Is there a vcvars*.bat in the Visual Studio installation directory?

[ravi2k18]

if we can not install manually then what is manual section in build & run ?

I have installed VS 2017 community version

              C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools\vsdevcmd\ext

What do you mean by installing VS 2017 in default path ? what is default path in my case ?

I have qt installed in the below path

        C:\Qt\Qt5.12.0

@ravi2k18

• Did you install Visual C++ ? That has to be selected separately during the installation.
• Did you change the path during the Visual C++ installation or did you keep the defaults?

@aha_1980

Did you install Visual C++ ?

I have installed VC++ using MS Visual studio 2015 iso download from Microsoft site.

Did you change the path during the Visual C++ installation ?
Yes. While installation I just used the non default path given below

                           C:\Program Files (x86)\Microsoft Visual Studio\2015

so I have installed VS 2015 with VC++ and tried to re import the code and configure the build and run settings as shown in below snaps. However still geting some build errors as given below.

@aha_1980

below is the snap of build and run

[aha_1980]

@ravi2k18 as said, you cannot set up the compiler manually. remove that one and use the auto-detected.

I'm on the mobile now and can hardly read your screen (most of the pic is uninteresting), so I cannot tell you if there is more wrong.

@aha_1980

Now I am using automatic kit Desktop Qt 5.12.0 MSVC2017 64bit
however while building the project I am getting below err.

                   File Makefile doesn't exist.

why VC++ project will use Makefile here? when has *.pro file.
How can I fix this?

Thanks....

[aha_1980]

@ravi2k18 qmake generates a makefile, which is processed by nmake/jom.

I'd suggest you to create a simple example with the wizard first and see if that compiles.

@aha_1980

when i create new "hello world" project by using empty qmake project template, it runs successfully.
However when I try to import the same dir as existing project after deleting generated .pro.user, it gives me

                 ":-1: error: No rule to make target 'all'.  Stop." 

any idea what I am doing wrong in importing the working exciting project here.

thanks...

@ravi2k18 make sure to delete all build artifacts and Makefiles. it should work.
