Version Confusion

[frankiefrank]

I've recently accidentally installed the wrong version of Qt: Got 5.1.0 64bit for VS2012, when I needed 32bit for VS2010 with OpenGL. I've uninstalled and installed the right version.

I've updated my path variables:
QTDIR is C:\Qt\Qt5.1.0\5.1.0\msvc2010_opengl
QMAKESPEC is win32-msvc2010

However now when I'm trying to build something (QWT), I get this error:

    cd src\ && ( if not exist Makefile C:\Qt\Qt5.1.0\5.1.0\msvc2010_opengl\b

in\qmake.exe E:\Software\qwt-6.1.0\src\src.pro -o Makefile ) && E:\Software\qwt-
6.1.0\jom.exe -f Makefile
E:\Software\qwt-6.1.0\jom.exe -f Makefile.Release all
Error: dependent 'C:\Qt\Qt5.1.0\5.1.0\msvc2012_64_opengl\include\QtCore\qglobal.
h' does not exist.

I don't understand why it searches for the older Qt version (2012 / 64bit) but of course it's not there, and I can't build my project.

Is there anywhere I should look to make sure I'm switched to the right version?

Probably some stale Makefile or configuration. Try a clean rebuild.
