QT Compile problem.

[UnLuckyGuy]

First, tell me if i should add that new compiled environment, or i just add "CONFIG+= shared " ?

Hi and welcome to devnet,

The -prefix option is used when you call make install (or mingw32-make in your case). So before going further to that to have your custom version installed properly. Then with Qt Creator, add this new version, make a Kit for it and then you can use it to build your application.

If you are starting your application outside Qt Creator, you have to first follow the deployment procedure. The most simple thing to do is to use windeployqt.

@SGaist But their is no qmake.exe, so how can i add that ne version? I compiled it two times.

[jsulm]

@UnLuckyGuy If there is no qmake.exe then your build failed or you did not execute "make install"

[UnLuckyGuy]

@jsulm I installed version 5.2, but in src, there is no Makefile, configure etc, there are just folder, and if i run the command prompt, then i do cd and configure, it says "Error, unknown command" or something like that.
How to generate those files? I n version 5.3.2 it's all there, but here not. I prefer 5.2, so now i must fix this issue too.

[jsulm]

@UnLuckyGuy What exactly did you install? To build Qt you need its source code.
You don't generate configure, it is already there.

[UnLuckyGuy]

@jsulm
In version 5.3.2, there are config files, and some more, in 5.20 there are folders only :O

In 5.3.2 if i just do:

cd: path, and use this commands configure -platform win32-g++ -release -shared
It's run, in 5.20 is give's me the error "unknown commands" or incorrect.
I am downloading 5.2.1, i don't like that 5.3.2, i build my program, and my tool has bad performance (The project has been created in 5.20).

So, i should use prefix command, in mingw32-make?

For example : mingw32-make -prefix c:/softwares/qt...etc ?

[SGaist]

Where did you download the 5.2 sources from ?

Just in case, you do realise that the current supported version is 5.10 with the LTS being 5.9 ? You are trying to use outdated versions of Qt which might not be the best bet in the long run.

[UnLuckyGuy]

@SGaist Men, it was something like 3-5 years ago... I don't know, other versions don't work with OpenGL in my case, so i use that. (It's not a openGl program, but i like this version). I remember, i donwnload it from here probably.

Sources are ther,in installation i check "sources", and it install it.
I am installing 5.2.1, will see, if they are there.

[UnLuckyGuy]

Nothing is there too, in version 5.2.1, only folders are there.
I am gonna download somthing like 5.6, or better, will see what happend.

[SGaist]

You can grab the sources from here.

Why 5.6 ? Do you have a technical limitation that forbids the use of a current version ? As wrote before, if you need LTS the current is 5.9.

[UnLuckyGuy]

@SGaist This is all messed up... I download 5.7, and it's compile, but it fails too. It create the qmake, but if i trz to us is, it's impossible to run anything, error "QT5 dll is missing" and "widgets module is not declared".

I am not gonna download any rusty scrap again. I have enough.

[SGaist]

You don't give any information about what option you are using so it's close to impossible to give you some hints.

By the way, why are you building Qt ?

[UnLuckyGuy]

@SGaist Men, listen, the only thing i do, is run the command prompt, set the path to the source, add:

configure -platform win32-g++ -release -shared

Then in mingw32-make if i try to use, that rusty junk doesn't work, i mean prefix:

-prefix C:/QT_Compiled/ABC/

And that's it, i do nothing else. When it's compiling, it ask me for opengl, but i can skip it, is not an error, but something like warning i think. I dont want ther OpenGL, at least now.

"By the way, why are you building Qt ?"

I wanna compile my tool, and send to my friend, with DLL's, not the source code.

[jsulm]

@UnLuckyGuy said in QT Compile problem.:

For that you do not have to compile Qt by yourself. Simply install precompiled Qt for your compiler and use it.

@UnLuckyGuy
Not related to your problem, but this forum has the neat option where you can make a screen shot and directly paste it in your post using CTRL-V (since you are working on Windows it seems). Or drag&Drop your image file directly into your post. That saves you the trouble of having to upload your image to some external site like mediafire first.

[UnLuckyGuy]

@jsulm If you help me, where to download the right Pre-compiled version, because i rly have enough of errors.

I have now QT 5.2.1 and 5.7 with MinGW 5.3 and 4.8, what version should i donwload of that pre-compiled QT? And where?

[UnLuckyGuy]

Guys, anybody knows what to do?? I need it, and i tried everything i can.

PS.Here is the error list.

What commands shold i use on mingw32-make ?? I tried t download that pre-compiled version, but i can't find it for QT.

Hi
Here is direct link to lastest version
https://download.qt.io/official_releases/qt/5.10/5.10.1/
you can go back to get older if you really need.
Make sure to select the mingw version as you not to have VS installed.

[UnLuckyGuy]

@mrjj But it's gonna compile? I need any working version to compile, and have the access to compile my tool. Even if it's 5.9, i just need it for compilation process.
