[Libevent-users] libevent 1.4.x compile error on windows 7/8

Hi there,

I'm trying to build libevent 1.4.x stable release on windows, using these steps:

  • From there, extract the libevent source to the location of your choice. Make note of this location, as you will need it later.
  • Open the Visual Studio Command Prompt (or execute the appropriate VCVARSALL.bat for your required environment in a terminal).
  • Navigate to the location where you extracted the libevent source, then execute the following commands: nmake /F Makefile.nmake
But I'm running on this error:
Note: I'm using MS Visual Studio 10 on Windows 7x64

Right now I'm stucked since I need to build the libevent to be used in other project build. I will really appreciate any help you could give me.

Thanks in advance,
