QSerialPort Library for Qt creator 4.8 on Debian 9

jsulm

@Digvijay Why do you build Qt by yourself?
As @SGaist pointed out Debian stable already provides Qt 5.7 (including 32bit).

Hi @Digvijay,

I guess you need to call sudo make install as last step.

But as others said, why don't you install the Qt version supplied by your distribution?

Because i do not want change my windows based GUI every time. I want directly compile project.

Sorry, I don't understand what you mean by this.

Yes i know that Qt 5.7 is available. But i do not know how to install it. Do i need to uninstall the Qt 4.8?? And how to install it on linux??
And one important thing is i have only one day of experience in linux. So i am sorry if i am asking silly questions.

Then before starting to develop you should first get to know the distribution you are using. Start by looking up the Debian package manager: apt. Depending on your desktop environment you might even have a GUI on top of it.

No you don't need to uninstall anything, Qt 4 and 5 can co-exist without any problem.

@Digvijay To add to @SGaist on Ubuntu (and most probably on Debian) there as a GUI tool to install/uninstall packages: Synaptic.
Install it using: apt install synaptic

What i mean is that, i have developed my application(UI) on windows. But for some reason i have to put the exe on linux. To do that i have to compile my application in linux or use cross compiler. Compiling application in linux is easier so i am trying to do that.

Yeah, thats what we do also. Where is your problem with that?

Regarding QtSerialPort, you have several possible solutions:

use Qt5 as provided by your Linux distribution
use the Qt5 online installer for 32 bit Linux (I think the last version is Qt 5.5.1)
compile QtSerialPort for Qt4 yourself
use a Linux distribution that has a newer Qt5
compile Qt5 yourself

If you are not limited to 32 Bit Linux, you can install the newest Qt also via the 64 bit online installer.

How did you finally install it ?

In any case, since you have it working now, please mark the thread as solved using the "Topic Tools" button so that other forum users may know a solution has been found :)

@SGaist with the library the mistake i was doing is that, i was cloning it two times. For installation of Qt 5 , i had to download right version of Qt which is compatible with my linux then installation part was easy.
