Re-Compile an old project from 2007

Hi Guys,

I have an old project that need to be recompiled again and I would like to know, if I could use the latest qt version.

I used in 2007 the following tools:

OS: Win XP
Compiler: MinGW 4.1
QT: 4.1.1

Can somebody help me to be able to recompile the project again? The reason I have to recompile is because I need to change some code.

Best Regards

Raphael

You could try with the lastet Qt4 version, there shouldn't be that much change there.

Cheers,

Re: Re-Compile an old project from 2007

Hi!

Thank you for your answer. I have installed the 4.1.1 Version and I have some errors. Is there maybe missing a path or a project file entry?

Hi amleto,

sorry for that my error has 29'635 characters and its only 1'000 allowed. I have attached the complete error code. Have you or somebody an idea?

Re: Re-Compile an old project from 2007

You indicated earlier that you had used Qt4 before, but that looks a lot like Qt3 code.

For example addMultiCellWidget in QGridLayout got replaced by addWidget having additional row-span and column-span arguments.

QListView got replaced with QListWidget, thus it is now QListWidgetItem instead of QListViewItem.

Cheers,

It might be using Qt3 compatibility layer.

Re: Re-Compile an old project from 2007

Hi Guys,

Yes I used qt3 compatibility later.

I have installed QT 4.8.4 now and minGW 4.4 on a XP Machine. Now I have compiled again and have "only" these errors:

Is there a magic line to add on my project file to compile this old project again? Any chance?? :confused:

Re: Re-Compile an old project from 2007

It's not a matter of the project file. The source code is incorrect, e.g. it is missing some include statements.

Re: Re-Compile an old project from 2007

Hi Wysota,

the code should be fine because I was able to generate the exe file in the year 2007. Is maybe because I am not using the same mingw version and qt version? I think that I used qt 4.1.1 and mingw 4.1 in 2007. Now I am using qt 4.8.4 and mingw 4.4.

It would be nice to be able to compile the project again without to change the code.

What would you suggest?

You really think nothing has changed in Qt during the past 6 years?

Quote:

Some of your source code files are missing includes. There is no way to magically change this without modifying the source.

abfrage.cpp needs:
Code:

#include <QListViewItem>
to get rid of most errors.

abfrage.h needs to include something that pulls in the Qt namespace before it tries to use the WFlags typedef. Almost any widget related include will do it, so you might just be able to reorder existing includes to achieve this.

If the ambiguous conversion error persists after fixing those then you'll need to work out how to address that.

Re: Re-Compile an old project from 2007

Hi Guys,

I found out that I used qt 3.3.4. I have installed qt 3.3.4 and was able to compile again. Thank you again!
