Hi, Daniel: I just installed version 1.40 under Windows, using the MSVC setup.
When I use the consult/1 predicate (or use File -> Consult from the menu), I get this error: GNU Prolog 1.4.0 By Daniel Diaz Copyright (C) 1999-2011 Daniel Diaz | ?- consult('C:/GNU-Prolog/bin/myClauses.pl'). compiling C:/GNU-Prolog/bin/myClauses.pl for byte code... C:/GNU-Prolog/bin/myClauses.pl compiled, 4 lines read - 354 bytes written, 410 ms uncaught exception: error(system_error('error trying to execute pl2wam (maybe not found)'),consult/1) | ?- Mine is a Windows XP Pro SP2 system. The current directory is C:\GNU-Prolog\bin, and for the sake of definiteness I've added that directory to the Path system environment variable. When I run pl2wam.exe from the command line in that directory, the file myClauses.wam is created without apparent error: pl2wam myClauses.pl and if the -w flag is added, then the myClauses.wbc file is created. Furthermore it can be loaded from the console without error, and my three clauses then correctly display: GNU Prolog 1.4.0 By Daniel Diaz Copyright (C) 1999-2011 Daniel Diaz | ?- load('myClauses'). (10 ms) yes | ?- listing. whoami(i). whoami(me). whoami(myself). yes | ?- Also out of an abundance of caution, I've tried running vcvars.bat before running gprolog.exe to ensure any other necessary environment variables are set. The same error appears when I consult/1 the Prolog source. A similar error occurs if I try consulting one of the examples directory source files. Rather than attaching my source file, let me just note that it consists of the three lines that appear above (preceded by a blank line, although omitting that blank line has no effect on the error). Running gprolog.exe from a command line produces a little additional output, namely USED DIRE: C:\GNU-Prolog\bin when the console is launched, and thereafter USED DIRE: . each time the File -> Consult... menu item is used. I looked at the directory for unstable versions, but there don't appear to be any yet (1.40 being such a recent stable version).
