Compiling errors, help for a beginner

Hey everyone, I’m new here, nice to meet this beautiful community!

I am writing my first IF, but I’m having issues with the compiler, so if anyone is willing to help I’d be grateful!!
I followed this guide PunyInform: Installing the tools and compiling a game – Vintage is The New Old to compile an .inf file exported from Trizbort, where I built the game world. But I get errors from the compiler, see attached picture.

the .inf content are as follows:

!% -~S

! The very first lines of the main source code file for a game can
! contain compiler options, like the lines above. -~S disables
! strict error checking. This is otherwise used in z5 and z8 games by
! default. While useful for debugging, it adds ~10 KB to the story file
! size and it makes the game slower.
! $OMIT_UNUSED_ROUTINES=1 makes the compiler remove all routines which
! aren't used. This can save some space.
! $ZCODE_LESS_DICT_DATA=1 removes an empty data byte for every dictionary word.

Constant Story "Lucid Dreams 1 - v0.2.0";
Constant Headline "^By A Trizbort User^^^";

! Uncomment ONE of the two following lines, to show either time or score/turns
! Leaving both commented out makes the library bigger.
!Constant STATUSLINE_TIME; Statusline time;
Constant STATUSLINE_SCORE; Statusline score;

! Comment out to keep track of score
! The value is what will be shown as the score on statusline in z3
Constant NO_SCORE = 0;

! Customize the statusline in z5+ (will have no effect in z3)

! Uncomment to add optional features to PunyInform
!Constant DEBUG;
!Constant CUSTOM_PLAYER_OBJECT = myPlayerObj;
!Constant OPTIONAL_FULL_SCORE; ! Comment out NO_SCORE when uncommenting this
!Constant RUNTIME_ERRORS = 0; ! 0, 1 or 2. 0 = smallest file, 2 = most info

! Define any library constants you need here, like MAX_SCORE, AMUSING_PROVIDED,

Constant INITIAL_LOCATION_VALUE = Ingressodellaproprieta;

Include "globals.h";

! Define your attributes, common properties and global variables here, if any

! Define the entry point routines you need here, like Amusing, DarkToDark etc.

! Uncomment to add PunyLib extensions
!Include "ext_menu.h";
!Include "ext_flags.h";
!Include "ext_talk_menu.h"; ! Note: Also include ext_flags.h to allow use of flags
!Include "ext_quote_box.h";
!Include "ext_cheap_scenery.h";

Include "puny.h";

! Uncomment to add PunyLib extensions
!Include "ext_waittime.h";

PunyInform doesn’t include darkness by default, so you’ll need to comment out this line from your code:

EDIT: To be clearer, the tutorial you link to was written a couple of years ago when PunyInform still defaulted to including the light attribute (used by the room in the example code). That has since changed, and recent versions of the library start with the OPTIONAL_NO_DARKNESS constant defined. If you remove or comment out that line, PunyInform will include the light attribute and so the old example code will compile successfully.


It worked! Thank you so much. But the line Constant OPTIONAL_NO_DARKNESS; actually comes from the sample file minimal.inf that comes with PunyInform, shouldn’t that be addressed?


The issue is really with the tutorial you’re following rather than the current version of PunyInform; all that’s happened is that the library has changed the way it deals with the concept of light and dark since that tutorial was written.

If the tutorial was written today, the code in Step 4 would be the same as the current minimal.inf, i.e. including the OPTIONAL_NO_DARKNESS constant, but omitting the light attribute when defining the Library object. By default, PunyInform will treat every room as lit and therefore the light attribute is unnecessary (and undefined).

Alternatively, you can choose to comment out OPTIONAL_NO_DARKNESS and PunyInform will set up the light attribute. You will now need to assign the light attribute appropriately in your game, otherwise rooms will be dark by default. However, this means you can now have puzzles in your game that depend on the player having a light source, etc.


Glad you got good help!

Just to add an idea of what you can do when you get compiler errors:

The compiler complained about the light attribute. If you look up the light attribute in the quickref document that’s included with the PunyInform distribution, you see this:


Or you could look at the appendix for attributes in the manual, and you get the same information. If you just search for “light” you find it soon enough as well.

Benvenuto su Intfiction, Davide !

I confirm what “r_f” has explained, and add that the documentation has a sizeable section, with a well-written table, about the optionals, (pp. 26-29) whose can be easily used as a convenient quick reference.

Thanks for explaining that! I am slowly becoming familiar with all the available material

Ciao Piergiorgio, grazie!

yes, in fact I still have to study the full documentation, I needed to have a development system in place as soon as possible so I can have something to play with and keep the creativity and interest alive. Time is scarce these days…
