mathbrush recently made the source for Grooverland available to the public:
I tried compiling it in 6M62 and I got three of those ‘You need to increase your MAX_PROP_OBJECTS’ type messages sequentially. Once I’d dealt with each case – by doubling the default value – it compiled. But when I asked mathbrush about this, he said he made it in 6M62. And so for him, it compiled without these additional value tweaks.
So what’s going on here? He’s using a PC and I’m using a Mac, but we’re building in a virtual machine, so I didn’t think that would make any difference. It’s a glulx game, so there’s no chance of one of us having the z8 box ticked or something.
Huh, weird – I’m on a PC, and I was just able to compile in 6M62 via the IDE without running into any of those issues. The source text does have some of those statements increasing various allocations:
Use MAX_PROP_TABLE_SIZE of 500000.
Use MAX_SYMBOLS of 50000.
Use MAX_NUM_STATIC_STRINGS of 50000.
Use MAX_STATIC_DATA of 300000
So it’s weird you’d need to increase them again.
Anyway figuring this out is way above my pay grade, but figured I’d offer the data point!
One idea I just had was that maybe we (me, versus you two so far) have different versions of the three included extensions. Two of them are vanilla, but I wonder about numbered disambiguation choices. All three are worth checking.
I’m using:
Version 7/140501 of Numbered Disambiguation Choices
Version 12 of Locksmith
Version 7/140425 of Basic Screen Effects
The stats I had to increase were not previously increased in the source.
I had to add:
Use MAX_OBJ_PROP_COUNT of 128.
Use MAX_DICT_ENTRIES of 2600.
Use MAX_OBJECTS of 1024.
Finally, here’s my compilation report:

I’ve got all the same extension versions as you, and likewise don’t see any manual updates to those limits in the text. Here’s my compilation report, if it’s useful:

Comparing them, all the virtual machine amounts are the same. The big difference is in the ‘Allocated’ section. Yours allocated 18376491 bytes of memory, mine allocated 31706703 bytes of memory. I could guess that’s a PC/Mac difference, but I still don’t get why it would affect those limits that are inside the virtual machine. I hope someone who does get it will come enlighten us
Edit: My compiler is 6.34 for Mac 2016, yours is 6.33N for Win32 2015. So I don’t know what kind of parity exists in that arena.
Up through 6.35, the Inform 6 compiler could be built with different default values for MAX_PROP_TABLE_SIZE, etc. It sounds like the Mac and PC builds had different defaults. That’s all. It’s not very interesting.
This has to do with internal tables in the I6 compiler. The generated game file would be the same.
(As of 6.36, all those settings have gone away, and the internal tables expand as needed.)
