how to install the QWT library for Qt creator on windows server 12 (development server)

[thippu]

@jsulm Yeah, I did click on the qmake.exe, It executed some auto cmds and the mingw32-make.exe did flash and auto closed, I don't know what to do.

[thippu]

@thippu Buddy, could you see this link and tell me where I have to correct myself?

[jsulm]

@thippu Please don't click anything! You need to use the command line, not the mouse. So, download and extract the QWT source code (or check it out from Git). Create a directory (lets say build_dir) and go there:

cd c:\build_dir
c:\Qt\5.11.1\mingw53_32\bin\qmake.exe c:\qwt_src\qwt.pro
c:\Qt\Tools\mingw530_32\bin\mingw32-make.exe
c:\Qt\Tools\mingw530_32\bin\mingw32-make.exe install

[thippu]

@jsulm I could not get what I have to do after the cd cmd from your comment.

[SGaist]

Hi,

Write the commands one line after the other as @jsulm shows in his post.

[thippu]

@SGaist , @jsulm could you clarify "c:\Qt\5.11.1\mingw53_32\bin\qmake.exe" and "c:\qwt_src\qwt.pro" are to be executed on same line ?

[jsulm]

@thippu

c:\Qt\5.11.1\mingw53_32\bin\qmake.exe c:\qwt_src\qwt.pro

here you're calling qmake.exe and give it c:\qwt_src\qwt.pro as parameter...

[thippu]

@jsulm I did execute second line "c:\Qt\5.11.1\mingw53_32\bin\qmake.exe c:\qwt_src\qwt.pro" on build_dir output is project ERROR: cannot run the compiler "g++' , output : g++ not recongnized as internal or external command,

**I do I have to execute the second line in c:\Qt\5.11.1\mingw53_32\bin **

[jsulm]

@thippu Press Win key on your keyboard and enter "MinGW" you will get a short-cut to a CMD window which prepares the environment to use MinGW. Execute all the commands in this CMD.

[thippu]

@jsulm Sorry to say this, Qt environment has been installed on the D: because of disk full in the C:,
I did press the Win and typed the MinGW but It is not getting popped.
what to do?

[jsulm]

@thippu If it is on D then simply replace C with D in the path.
The CMD is located in d:\Qt\5.11.1\mingw53_32\bin\qtenv2.bat

[thippu]

@jsulm I have done it in the address.

[thippu]

@jsulm shall I execute cmd "qtenv2.bat" on "d:\Qt\5.11.1\mingw53_32\bin" ?

[jsulm]

@thippu Yes, double click it...

[thippu]

@jsulm yes, It said "Setting up the environment for Qt usage.... " thats all, next what has to be done?

[jsulm]

@thippu I already said that you need to enter all the commands I mentioned above in that CMD window...

[JKSH]

@thippu said in how to install the QWT library for Qt creator on windows server 12 (development server):

next what has to be done?

First, spend some time to learn how to use the Command Prompt. Example tutorial: https://www.youtube.com/watch?v=MBBWVgE0ewk

After you learn how to use the Command Prompt, read through @jsulm's instructions again; they should be clearer then.

[thippu]

@jsulm , QWT has been installed in C: drive and I copied qwt folder to D: drive, what I have to do next?

[jsulm]

@thippu It shouldn't be installed on C drive if your Qt is installed on D.
You executed

d:\Qt\Tools\mingw530_32\bin\mingw32-make.exe install

?
But if it is now installed then you should be able to use it in your project.

[thippu]

@jsulm , Yes buddy it got installed on c: drive.
In a project file .pro, I did add CONFIG+= qwt and execute qmake and it is successful but if do #include<qwt_plot> and build it says "qwt_plot:No such file or directory"
