How can I build 64 bit app on a 32 bit system (Using VS2008 IDE)
There have two topics about cross-arch build. One is “How can I build 64 bit Qt on a 32 bit system ?”, the other is “How can I detect in the .pro file if I am compiling for a 32 bit or a 64 bit platform?”
But How can I use VS IDE to build 32bit/64bit app? Change the “Configuration Manager “ , When build 32bit app, use “Win32” tag, build 64bit app, use “x64” tag.
Currently, I build QT 64bit Lib on X64 platform, and copy these Lib on :C:/QT/Qt64bit/bin , 32bit Lib: C:/QT/QtVersion/bit
Whether I only build the app src use “Win32” and “x64”, and copy the right QT arch Lib?
