...Got it. Had to use quotation marks instead of <>. didn't know I could do that. thanks, basic c++ programming class from college. thanks, stack overflow for teaching me stuff.

End result is #include "pdc34dllw/curses.h" which compiles and gets no errors.

EDIT: Nope, don't got it. Attempting to use the code specified in the tutorial that's juuust after including curses, the part that should work if I included it correctly, results in errors. Errors are all "undefined reference to x" where "x" is whatever is in each line of code below.

Spoiler: this copypasta gives errors (click to show/hide)

Code: [Select]

	initscr();			/* Start curses mode 		  */
	printw("Hello World !!!");	/* Print Hello World		  */
	refresh();			/* Print it on to the real screen */
	getch();			/* Wait for user input */
	endwin();			/* End curses mode		  */

Did you configure your IDE's linker for the library?

Considering I have no idea what that means, probably not.

Googling has taught me how to do that. I have now done that. Hurray, getting somewhere.

If anybody out there wants to learn how to do the internet stuff in Unity, I recorded a couple videos on it. I can promise that I'm almost certainly not the worst teacher on YouTube, but no guarantees.

I'm having a big problem with my code for my final project for Javascript. Its supposed to be a card counter that is supposed to count how many cards there are and spit out a total, if you're over or under a deck limit, and then spits out all the cards you have, the amount you have and it will tell you and prompt you again if you entered a card amount over the limit (in this case, its 3, though can be changed).

So far, if you enter a double, it enters a loop of "can't do that, enter another amount" even if its a valid amonut. Also, it seems to lose its shit if I enter 0...

On another note, if you somehow bypass the doubles, it seems to take the list and bash the numbers together for the total amonut instead of adding it together
(EX: "You have 03123131213232 cards" instead of "You have 27 cards")

Code: [Select]

I know its hard to look at, but please bear with me on this. I'll also take any recommendations to make it look... Cleaner? (is that how I would describe it?). I also would like it if someone can explain to me whats going on...

Kinda got left in the dust, so bumping my post because I'm still bashing my head off the keyboard trying to figure out whats making my program flip tables when I enter 0...

Considering I have no idea what that means, probably not.

Googling has taught me how to do that. I have now done that. Hurray, getting somewhere.

an include file gives the definitions of the functions and stuff so that your program passes the compile stage. But most libraries don't include the entire functions inside the .h file. The .h file just specifies function names and what data types they take as parameters. In the first compilation pass, the compiler puts in "dummy" calls to all functions that are in another module (i.e which have their body in a different .cpp file). The final "linker" stage works out the actual memory address for each function, and replaces the dummy function calls in each module with a real memory address.

Since there are different stages which are checking for different things, you need to keep and eye on what stage you get error messages. If it's during the stage when .cpp files are being processed, then it's an error in your code somewhere. If it gets to the linker stage, then it's often not a syntax error, but there was a function call where the body of the function wasn't defined in any module which has been included in the project.

Modules usually have a separate .cpp file, which also needs to be part of your project, or they have a pre-compiled .cpp file distributed as "thingname.lib" that has all the actual function bodies in it. You need to tell your IDE's linker that the lib file is part of the project otherwise you get "undefined" errors when the compiler does the final pass to stitch all the code together. In Visual C++ you can open your Properties for the project, and add your new lib to the list of libs. I think it's under a "Linker" section.

For PDcurses, I *think* you also have to compile with a special option, -pdcurses or something like that. I don't remember exactly.
It's ass to get working, but that seems to be the case for everything related to using external libs.

Reelya · « **Reply #7236 on:** April 21, 2015, 01:13:51 pm »

@miauw62 - I didn't have any trouble getting it working at all, just link the .h file where it's need and put the .lib with the existing list of lib files to include in the linker. It took me a couple of minutes getting it set up. Note, this is from the pre-compiled one I linked. It is hard to work out how to compile it yourself, so I just use the compiled DLL version.

@highmax, you're not actually changing the value of "cardDouble" back to false in the inner loop of the "cardRepeat" function, hence it never breaks out of the loop. This also causes issues when the next card is picked, since cardDouble is left as TRUE all the time. One good rule of thumb is to always set cardDouble to false at the start of each cardRepeat call. This will prevent previous values of cardDouble from wrongly affecting the result. I didn't get the incorrect addition problem though and couldn't replicate the problem with entering 0. When does that happen? I think it's probably related to not reseting cardDouble when needed.

miauw62 · « **Reply #7237 on:** April 21, 2015, 01:31:56 pm »

It's really confusing for a beginner though, since you have no fucking clue where you have to add references to the library.

Reelya · « **Reply #7238 on:** April 21, 2015, 01:33:32 pm »

It's pretty much the same for every library though, so it's just something you have to learn once, and no harder than any other language feature.

Anyone familiar with javascripts node.js and Browserify functionality? I'm trying to access node.js's buffer class, and in order to do that I'm trying to bundle it with my code with browserify. Of course, now I'm getting "ReferenceError: JSAgoraLib is not defined" when it slearly is defined in this file: http://angle.webfactional.com/JAgoraHTTPServer/js/libs/bundle.js. Anyone have any idea what my problem is?

Want to make sure I'm understanding this right. Say I have an array full of '#' chars.

Spoiler: array 1 (click to show/hide)

Code: [Select]

char arrayOne[10];

//this could be imagined as this: 
//1  2  3  4  5  6  7  8  9  10
//#  #  #  #  #  #  #  #  #  #

Spoiler: array 2 (click to show/hide)

Code: [Select]

char arrayTwo[10][2];

//this could be imagined as this:
//  1  2  3  4  5  6  7  8  9  10
//1 #  #  #  #  #  #  #  #  #  #
//2 #  #  #  #  #  #  #  #  #  #

So that to access contents, arrayOne would be arrayOne[X] which would be slot X, or coordinate (X,0) on the graph, where arrayTwo would be arrayTwo[X][Y] which would be the slot at coordinate (X,Y) on the graph.

miauw62 · « **Reply #7241 on:** April 23, 2015, 01:40:05 pm »

In C++, your array would be numbered from 0 to 9, not from 1 to 10. This is true for most programming languages.

Right. Forgot about that. This was just hypothetical.

So other than that, I'm understanding this right?

miauw62 · « **Reply #7243 on:** April 23, 2015, 01:48:20 pm »

Think so, yeah. I wouldn't recommend actually using arrays in C++, though, and especially 2D arrays. imo vectors are much easier to use.
