Problem - Kernel32.lib

[Guilherme Dantas]

Hello all,

I am new to QT, and I tried to reinstall the QT-SDK 5 times, but the following problem persists: when I try to compile the program, the message

:-1: error: LNK1104: cannot open file 'kernel32.lib'

. (It happens with all programs that I try to compile)

More details of the output:

14:55:25: Running build steps for project teste...
14:55:25: Configuration unchanged, skipping qmake step.

Error while building project teste (target: Desktop)
When executing build step 'Make'

My operating system: Windows 7 - 64 bits
Version of QT Creator: 2.4.1

More informations: I also use microsoft visual studio 2010. I tried to install mingw in my QT Creator and the error is still present. I also found the kernel32.lib in my computer, it's in the following directory:

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib

I would like to know how I can make my QTCreator work. I don't care if I will use mingw or the visual studio compilator, I just would like to have a fast solution

I fould in the internet other ppl asking the same thing but the answers are not precise for a beginner or are not clear.

Thanks in advance,

How did you inform the compiler where to find that library?

[Guilherme Dantas]

Good question wysota: Actually I did not do anything: the configurations of the compiler, of the linker, etc. were all automatically determined after I install the program (and I do not know how to configure the kernel32.lib path - that would be interesting, and would maybe solve my problem). I tried to install Mingw, I tried to change some building configurations, but I still cannot find the root of my problem.

So it's not surprising it can't find it

How did you tell your compiler to actually try to link with kernel32?

[Guilherme Dantas]

I did not tell anything to my compiler, I just installed the program and the configurations were automatically set.

I do not know how to choice the path of my kernel32.lib and every configuration that I use was auto-detected. How could I actually inform my compiler to not use kernel32.lib or to use a correct path for it? I am a complete beginner with QT

Do you need kernel32.lib for anything then? What are you trying to build?

I don't think Qt has anything to do with this. The problem seems to be with your MSVC installation.

I really don't need kernel32.lib, It's just for a simple project of a discipline of my university...and my visual studio works perfectly. So, how could I solve the problem?

Thanks for all the help

If you are familiar with MS VS-2010. It will probably be easier for you to work from there.
You've already installed QT SDK so all you need to do is install the QT MS Visual Studio 2010 add-in. Just Google "qt-vs-addin-1.1.11-opensource.exe" to find where to download from.
Make sure you set the environment variable QTDIR to point to QT install directory (c:\Qt\4.4.8 or something like that).

The VS add-in should take care of setting up everything else. It adds templates for Qt projects to your New Project dialog.

So what does your project file look like?

From that link command it looks like the Qt binaries installed are MSVC 2008.
Guilherme is using MSVC 2010 in Visual Studio 2010 which is a binary mismatch.
In the Qt SDK updater download and use the MSVC 2010 Qt libraries rather than the 2008 ones.
