Unable to build DiffImg project

bitsystem

Well, It seems I Need to install Vs 2010 in order to build the project. Ok, I'll try to install this version and for sure I'll tell you if I'll solve the issue. Thank you very much.

@bitsystem
Well it will be easier as Qt4.8.X has a vs2010 version
so with a bit of luck. it will just work.
https://download.qt.io/official_releases/qt/4.8/4.8.7/qt-opensource-windows-x86-vs2010-4.8.7.exe

The build docs for linux mentions Qt4 so I assume its that version.

SGaist

Hi,

Qt 4 is really not that hard to compile on Windows, you should go on with VS2015 and build the whole thing.

Depending on what you need that project for, there might be more recent alternatives.

bitsystem

SGaist, what do you mean?
Simply, I need to build and run the project I've linked.
As I've already saym I've VS 2015 installed, however it seems impossible to build that project because many errors occurs (please, see all thread).

If you are right, you should be able to compile DiffImg project, if so, please, tell me how you do this :)

@bitsystem You're using Qt 4 this is not working with VS2015 as it was built with an older VS (different Microsoft compiler are not compatible with each other). @SGaist suggested you to compile Qt 4 by yourself with VS2015 if you want to use VS2015.

bitsystem

I've tried to follow the suggestion by mrjj without luck.

The type of errors changes, but there's no way to build correctly the code.

Visual Studio 2010
QT 4.8.7

Nothing to do. I'm sorry. However, thank everyone for helping me.

mrjj

@bitsystem
you tried to compile or own version of Qt ?

bitsystem

I've tried to compile the project by using VC++ 2010 compiler and QT 4.8.7 which I've downloaded yesterday..

mrjj

@bitsystem
That should work pretty ok.
You are not showing the actual errors you get so its hard to see if we are close or far,far away.

You did install the Qt 4.8 - 2010 version yes?
(qt-opensource-windows-x86-vs2010-4.8.7.exe)

bitsystem

Ok, I'll tell you every step I've done:

1 - Build on root project with error: cannot open file 'opencv_imgproc.lib'

2 - So, manually I go on 3rdparty folder and copy all *.lib files within "debug" folder I've defined, then I try to build again, but I get another error: cannot open file z.lib.

3 - I notice that doesn't exists any z.lib, instead I've a library which name is zlib.lib. So, manually, I open Makefile.apps.Debug file, and replace z.lib occurence with zlib.lib. Then, I try to build one time again and I get two errors:

tiff.lib(tif_win32.obj) : error LNK2019: unresolved external symbol __imp__MessageBoxA@16 referenced in function _Win32WarningHandler

So, at this poin I really don't know what could I try again..

mrjj

@bitsystem
Hi
Before you try the project.
Please try to make a standard GUI application to see if your new kit is working

Also, all dependencies seems to have a .pro file to build them.

About the error
unresolved external symbol __imp__MessageBoxA

try to insert
win32:LIBS += -luser32

in the. pro file.

bitsystem

Perfect!
Now it seems build correctly with win32:LIBS += -luser32 instruction.

mryy you have been precious.

Thank you very much!

mrjj

@bitsystem
Really ?
Good work!!
