Compiling Microsoft Detours for 64-bit

Question

The detours package claims to support 64-bit but I don't see a way to compile 64-bit binaries:

Detouring 32-bit and 64-bit Processes

Using nmake all compiles only 32-bit stuff:

>dir
 Volume in drive D is Volume
 Volume Serial Number is XXXX-XXXX

The nmake size64 command is invalid.

If I use the library ( lib.X86 folder) in my Visual Studio C++ project which is configured to produce a 64-bit DLL , I get the respective error and it won't build:

library machine type 'x86' conflicts with target machine type 'x64'

Renaming the folder lib.X86 to lib.X64 also does not work.

How can I get it to work in a 64-bit environment or is it not possible?

Answer 1

It seems like you have to set the target processor to 64-bit and then compile . A working batch ( .bat ) script may be something like the following (depending on your Visual Studio installation):

SET DETOURS_TARGET_PROCESSOR=X64
CALL "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build\vcvars64.bat"
NMAKE

With this, the 64-bit binaries should compile successfully.

Answer 2

On the command line, you can say

set DETOURS_TARGET_PROCESSOR=X64

and then do the nmake command.
