I am running a project with platform WIN32 but my laptop is 64bit. So if I choose the target machine type x64 it will announce : error LNK1112: module machine type 'X86' conflicts with target machine 'x64' File opencv_ts300.lib Then when I change the target machine type X86 it will announce error LNK1112: module machine type 'x64' conflicts with target machine 'X86' File Assemblyinfo.obj. So what should I do? Please help me. Thank you
