The Powder Toy

GAPDaTsar

So I go to compile The Powder Toy source code and for some reason I always get an error saying "PT_NUM" was not declared in this scope. What does this mean and how do I fix it?

Which guide are you following, the scons one or the visual studio one? Or are you just trying to compile on your own? I recommend using one of the guides.

If PT_NUM isn't defined ... you have a lot of problems. Maybe it can't find the include files.

The include files? As in the folder that contians the graphics.h, interface.h, defines.h and all those other files? Which one of these header files is PT_NUM defined in?

It looks like it's in src/simulation/Elements.h

I'm using the old C, not C++, TPT code. So I can't find an Elements.h. So where can I find the PT_NUM definition in the old TPT?

Oh, you should probably just use the makefile then. "make powder-sse3.exe" on windows or "make powder-sse3" on linux. my mod's Makefile might have some unknown fixes too.

Or if you are using visual studio there's this old guide: https://powdertoy.co.uk/Wiki/W/Compiling_tpt_with_Visual_Studio_%28old%29.html (the only one for the old c source).

Also PT_NUM is in includes/powder.h in your case

I found it. On line 532, it says #define ST PT_NUM. Yet the program says that PT_NUM was still not declared in this scope.

It should be here: https://github.com/simtr/The-Powder-Toy/blob/legacy/includes/powder.h#L240

I know where the file is and where PT_NUM is defined. It just does not want to work however. It still says PT_NUM was not declared in this scope.

PT_NUM?
