Windows Support

trec_eval can be compiled natively for Windows, using Visual Studio build tools, or using Cygwin

Compiling using Visual Studio build tools

See the Github Workflow for compilation.

A few additional includes are used:

  • mman.h - a mmap() implementation for Windows
  • unistd.h - dropin replacement for the Unix header file unistd.h
  • ya_getopt.h - BSD licensed getopt_log() implementation

The resulting .exe can be used natively on Windows without any further dependencies.

Compiling on Cygwin

Download and install the Cygwin platform. You will need make and gcc installed by Cygwin. To achieve this, on top of the default Cygwin installation, it is recommended to install automake, make, gcc, cygwin-gcc and git from the Develop category, and permitting dependencies to be installed.

Then, to compile trec_eval, open a Cygwin Terminal, navigate using cd to the directory of the trec_eval source, and type make.

Running on Cygwin

The resulting trec_eval.exe should be usable directly from the Cygwin Terminal.

The resulting trec_eval.exe should be usable on any machine without Cygwin installed, as long as the cygwin1.dll is available. For instance, place a copy the cygwin1.dll from Cygwin's /bin directory into the same directory as trec_eval.exe.
