project with a dll and a testprog (doesn't compile)

[aMan]

So how can i get the lib file?

I've tried compiling the lib statically and a calina.lib was created, but the result of compiling the tester was static too.

I've looked into the qt/lib directory. For instance QtGui has 9 files:
QtGui4.dll
QtGui4.exp
QtGui4.lib
QtGui.prl

QtGuid4.dll
QtGuid4.exp
QtGuid4.lib
QtGuid4.pdb
QtGuid.prl

I assume the d in the second list stands for debug, because there is also a pdb file (program debug file from vs). But there are still 4 files for one lib, in my project there is only one (calina.dll) created.

[marcel]

It will be generated automatically...
It is by default placed in Debug or Release, depending on which target you compile/.

Regards

[aMan]

They aren't. In the debug/releas folders are only the moc_blabla.cpp, blabla.obj and calina.intermediate.manifest files.

[fullmetalcoder]

check out your destdir... the .lib (and maybe .exp whatsoever...) should be in the same dir as the .dll unless they fail to be created which you would see when compiling the lib.

[aMan]

I've looked into all directories, I've even tried to remove the target and destdir variables, but nmake always creates only the dll..

Maybe I could post the project as an zip file and you look into it (if that isn't too much work)?

[fullmetalcoder]

can't you send us the very last lines of compilation output? Those which would inform us of the linking process... If I remember well, under Windows, a missing symbol (e.g. a function defined but not implemented) can prevent the import library from being created...

There are some warnings because of converting double to float, but i don't think that should make any difference..

That is what you should get.

I now have nearly the same pro file (only some more headers and sources), I have even dropped the double->floats and the opengl support.

But the lib files are still not generating..


Edit: I now see, that there is a difference. I have VS 8 (2005, no sp1) and you 7 (afaik 2003). Is that importand?

[marcel]

Can you post the code for the library?

The problem must lie there.

Regards

[aMan]

here you are..
and thanks for looking into it..

[marcel]

Yes. You didn't export anything for the library so the linker didn't need to create a lib.
You have to add Q_DECL_EXPORT to every class you want to export.
Something like:
