Problems with shadow builds and static release linkage

[qtacc32]

Hello,

I'd like to have multiple builds of qt, configured differently.
I'm using Visual Studio 2013 for that.

My plan is:
\build_dev as debug shared
\build_app1 as release static
etc.

\build_dev\qtbase\bin is in my PATH, and \build_app1\qtbase would be added as a new Qt version to the Qt Add-in.

In \build_app1\qtbase for example, I created the symlinks bin, include and mkspecs pointing to \build_dev\... (and also symlinks for the debug import .libs). That way, applications built in debug mode should use dynamic linking and in release mode, they should use \build_app1 etc. and static linking.

Debug build works fine, but when I try to build in release, I get these linker errors:

moc_MainWindow.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: static struct QMetaObject const QMainWindow::staticMetaObject" (__imp_?staticMetaObject@QMainWindow@@2UQMetaObject@@B)
...
Main.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall QApplication::QApplication(int &,char * *,int)" (__imp_??0QApplication@@QAE@AAHPAPADH@Z)
...
MainWindow.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: static struct QMetaObject const QAbstractButton::staticMetaObject" (__imp_?staticMetaObject@QAbstractButton@@2UQMetaObject@@B)

Does the Visual Studio add-in even support creating an app with static Qt linkage?
Or is it a problem with my shadow builds and the folder structure I have?

What I found is that if I link with QtWidgetsd.lib, these errors go away! But it's a release build, how can that be?
I checked Qt5Widgets.lib from the static release build and found the symbol ?staticMetaObject@QMainWindow@@2UQMetaObject@@B (without __imp _), then I checked QtWidgetsd.lib from the dynamic debug build and found __imp_?staticMetaObject@QMainWindow@@2UQMetaObject@@B.

What is going on here?

I really hope someone can help me... I've been working the last 2 days on this with little sleep to get this working :(

Thank you!

Whew! I think I got it...

The mistake was to use the includes of shared \build_dev when building in release.
There is only one little difference which made everything work: qconfig.h!
It defines QT_STATIC in the static \build_app1 ...

The debug config of the project created by the Qt Add-in has to be adjusted a little though:
Include directory $(QTDIR$)\include =>...\build_dev\qtbase\include.
Lib directory $(QTDIR$)\lib =>...\build_dev\qtbase\lib.
The project still uses \build_app1\qtbase as Qt Version.

That way, the Debug build looks for includes and libs in \build_dev while the Release build looks in \build_app1.
And the .lib symlinks are not necessary anymore, I just kept the bin directory symlink.

Just in case someone else wants to do something like this...
