Solved Error: Compiling legacy Souce code
-
Hi koahnig,
Thank you for the reply.
"You gat a pretty old Qt creator version, I suggest to upgrade to version 4.5"Sorry the QtCreator version was 4.5.0 intead of 2.5.0.
When I used this version there were lot of error related to header files missing. The application used headers file that are not supported by the Creator 4.5.0. I looked at these header and they are not user header but the part the IDE package, I think. This why I am looking for Creator version that created the project back in 2011."The most important is that what the actual Qt library version was used for your application. Was it Qt 3 or Qt 4? I do not think that Qt 5 was already in place around there."
It is hard to tell which Qt version. I think it is Qt 4.7.4 and MINGW530_32. I agree, it wasn't Qt 5.
"Which is the Qt lib version you are using now?"
I am trying different QtCreator and see if the error disappreaded. This morning, I tried QtCreator 2.3.0 which its About DialogBox info show that is based on Qt 4.7.4 and it was built on 31/08/2018. So I installed Qt 4.7.4 and I compiled the project using the creator 2.5.0.
This time all the error related to missing header file disappeared.
I got only:
Warning message : Qt: Untested Windows version 6.2 detected!
and Error messages:**g++: ../Build/debug/libsa430dbg.a: No such file or directory
g++: C:/Qt/4.7.4/lib/libqwtd.a: No such file or directory**
It seems to me that this Creator version has the built in header files and this is why there is no error related to missing header or maybe I did spoke too soon.
The other two error, I haven't the slight clue.
Any idea? -
Hi @robrob,
once again: Qt Creator has nothing todo with the header files needed for building your application.
Important it the Qt version. And as @koahnig already said, you can use an older Qt version together with a newer Qt Creator. E.g. I'm using Qt Creator 4.5 together with Qt 4.8.2 and Qt 5.9.4 on Windows 7.
Which Windows version are you using?

I recommend that you are installing Qt creator with online installer from there either commercial or open source version.
The online installer forces you to use the newest version of Qt creator. With the online installer you should be able to install also older Qt lib versions with the correct compiler version. At least you will have something which should work.
AFAIK you should be able to install Qt 4.7 and recompile. Typically all is setup correctly.

Hi Koahnig,
Thank you for the reply.I am suing Window10 64-bit.

Hi,
This version of Windows wasn’t even in development when 4.7 was released.
You should consider using 4.8.7 which is the latest and last of the Qt 4 series if you can’t upgrade to Qt 5.

Hi,
You setup the Kits, then you can choose which one you want to use with your project.
-
Hi SGaist and thank you for the reply.
You setup the Kits, then you can choose which one you want to use with your project.
Is it by going to Option -->Qt4 --->Qt version tab---> add
then choose the qmake relative the wanted Qt version. -
You should consider using 4.8.7
Does this version include these header files https://doc.qt.io/archives/3.3/headers.html? -
If your Qt version is not already listed then yes, first add it and then create a Kit using it.
Take a look at the Qt Creator documentation on the subject.

@SGaist
About The Qt Creator version and the Qt version. When I pressed Help-->About Qt Creator to see which version I have the following for version 2.3.0:
"Version 2.3.0 based on Qt 4.7.4 (32bits)"
This made me believe that this version of Qt Creator work only with Qt 4.7.4. Am I got it wrong ? -
Yes you are wrong.
As already explained, Qt Creator is an IDE. What you see in the about box just tells you the version of Qt used to build Q Creator and that you would have to use if you were to build a plugin to be used by that version of Qt Creator.
It doesn’t matter for the various versions of Qt you want to use to build your applications/libraries.

@SGaist
Thank you SGaist for clearing this up of my mind , that's one confusion out of the way! -
For example if i use the following in my file
#include <QMessageBox>
#include <QColor>
#include <QColorDialog>
#include <QUrl>
#include <QDesktopServices>Does the Qt contain these header file or where they live because they are not user defined header?
-
@robrob said in Error: Compiling legacy Souce code:

Yeah, they are part of Qt, and also the corresponding shared libraries.
You can easily find them by looking into your Qt installation directory.

Thanks guys for the help.
I think now I understand the principle of Qt and Qt Creator.
So the build process doesn't generate error related to legacy include files.
However there is error which I don't have a clue what is about.
Below is the output of the compiler:Running build steps for project SA430Gui...

The two errors are highlighted in bold font
There is no much information why it failed.The config part (from the SA430GUI.pro) are below:
CONFIG(debug, debug|release){
LIBS += ../Build/debug/libsa430dbg.a
LIBS += C:/Qt/qwt-6.0.0/lib/libqwtd.a
TARGET = SA430GuiDbg
}else{
LIBS += ../Build/release/libsa430.a
LIBS += C:/Qt/qwt-6.0.0/lib/libqwt.a
TARGET = SA430Gui
}Just to remind that this an open source code that was given to me. It is a legacy code (2011).
In desperate help please!
NB: I don't mind sharing the source code with anyone who want to look at it. -

Especially LIBS += C:/Qt/qwt-6.0.0/lib/libqwt.a is really, well, bad.
Do you have these files in this directories? -

Do you have these files in this directories?I searched for them and I couldn't find any.
Also the folder C:\Qt\qwt-600 doesn't have lib subfolder.
Strange is it? -
qwt is an externally library based on Qt. You need to download and compile yourself separately.
I guess you can use a newer version, but you need to try.
