Hi Tony,
This is how I modified the .pro files of my projects:
win32 {
contains(QMAKE_HOST.arch, x86_64) {
QMAKE_LFLAGS += /MACHINE:X64
} else {
QMAKE_LFLAGS += /MACHINE:X86
}
}
IIRC this selects X64 if you run Windows 64 bit. You would have to omit the
check if you only want 32 bit builds now. I don't know how you select this
setting depending on the Qt libraries you use for a given build.
Hope it helps,
Ben
