Question

I need to build a Qt5 64 bit program which links to static .lib libraries (compiled with /MT). I tried changing the lines below from MD to MT:

QMAKE_CFLAGS_RELEASE    = -O2 -MT
QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MT -Zi
QMAKE_CFLAGS_DEBUG      = -Zi –MTd

in the file D:\Qt\Qt5.0.0src\qtbase\mkspecs\win32-msvc2010\qmake.conf

and recompiling it with

configure -prefix %CD%\qtbase -debug-and-release -opensource -platform win32-msvc2010 -opengl desktop

and then nmaking it, but it failed with:

XPathGrammar.cpp
Generating Code...
        lib /NOLOGO  /OUT:release\WebCore.lib @C:\Users\Paul\AppData\Local\Temp\WebCore.lib.4480.3319717.jom

It seems that the “SettingsMacros.obj” file doesn’t get generated. Why is that?

Do I need to include “-static” in the configure string? I know that Qt doesn’t get along with /MT but my project needs it otherwise I would not be able to link those .lib files

Answer 1

yes, you do need to add -static. Worked for me.
