[Boost-users] How do I build x64 binaries with Boost source?

Hi, How do I specify that I want to build 64-bit binaries when I run bootstrap and then invoke b2? I had a linker error saying, “1>libboost_thread-vc141-mt-gd-1_64.lib(thread.obj) : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'” when I tried to build an ISAPI extension DLL with Wt (just a simple app using the same code as in the “Hello world” example). [Note: I’m just trying out the wtispai.lib/wisapid.lib connector libraries to see how to use them.] Any help would be appreciated. Thanks in advance.
