I have written a prolog program in GNU-Prolog and successfully compiled it , now I want to create an executable file so that the other person only need to click on that file and run the program. I want to know if there is a way to create an executable file from a GNU-Prolog program?
Under Windows, to compile to an executable you need a C compiler toolchain. Depending, on the version you installed, you need the Microsoft C++ compiler (MSVC) or with gcc (provided by MSYS2/mingw64).
For MSVC, you can install Microsoft Visual Studio 2019 Community (version 19.28.29335). Once installed, there are 2 .bat file provided with the MS compiler e.g. vcvars32.bat and vcvars64.bat. Launch the appropriate .bat to obtain a terminal with PATH sets for MSVC.
For gcc, you should install MSYS2 + the gcc toolchain. More information is available here WINDOWS information (the file details how to compile gprolog on WINDOWS using either MSYS2/gcc or MSVC).
The gprolog compiler is in the bin sub-directory of the GNU Prolog installation (by default C:\GNU-Prolog\bin). You need to add this directory to your PATH.
Go to the directory containing your Prolog file (cd path_to_your_file) and compile it with gplc your_file.pl.
As mentioned by Paulo, you'll find more information on options you can pass to gplc in the online manual.
