C++ Question Weird errors at compile time, no obvious solution.

[Zatnikitelman]

Ok, so I've decided to branch into the wonderful world of C++ Orbiter Programming. I got ShuttlePB to compile OK thanks to some guys on the IRC, but now that I've decided to create my own vessel from scratch, I've run into a few hiccups. I've been able to solve most of the initial errors, but these last few continue to elude me.
First is the .cpp file, second is a readout of all the errors.
Thanks for any help,
Zat

BTW-I'll be hangin' around the IRC till who knows when so if it's easier for you or whatever, just speak up there.

[ex-orbinaut]

I am reasonably new to this myself, but there is one thing that seems plainly obvious with a glance at your code.

You have #included a specific h file for your vessel, yet you still define the vessel class in the cpp. Had a similar experience; never got it to work. If you have the h file, define the vessel class and declare your functions there. That works. Otherwise, don't have the h file at all (that's applicable for the way you seem to be doing it). The vessel does not look complicated enough to merit one.

I wouldn't /* comment out * / arguments that are required in a callback function. Use them or ignore them, as you need (I am referring to void _SSM::clbkLoadStateEx (FILEHANDLE scn/*, void *status*/). Look at the API reference for info on what arguments are required for each API function.

Not too sure that setting your general vessel constants in a callback is exactly right. Not tried it. However, do that in the h file aswell, if you have one, or outside of functions in the cpp, if you dont. That also works.

Hope it helps point you in the right direction. Look at the ShuttleA sample in the orbitersdk\samples as an intermediate example to base your vessel on (with h file), or ShuttlePB without h file.

Somebody better than I could help you with the finer points.

First is the .cpp file, second is a readout of all the errors.

...
#include "SSM.h"

Check that ssm.h file. Could be you simply have unbalanced '{}' or forgot a ';' after some class definition or a function prototype.

 

[Zatnikitelman]

Ok, I cleaned up a little, commented out the preprocessor include "SSM.h" so now all I'm getting is the syntax, unexpected token, and unexpected end of file errors. The only reason I'm commenting out the arguments is because I think those arguments are only used during an overload which would only be when I'm declaring my own stuff instead of just going with Orbiter default. Nothing's changed in my code except commenting out the include "ssm.h"

I'm also curious about something else because I had to rename my class as _SSM because it kept tossing an error along the lines of: "SSM already defined as namespace" and going with _SSM as my class did the trick.
Again, thanks for any and all help,
Zat

Are you actually using anything in stdafx.h? If not get rid of it. Either way, check you have precompiled headers turned off - I have had trouble with them in the past and the compile time for Orbiter modules is not really all that long.

 

[MeDiCS]

I'm pretty sure you have to declare ORBITER_MODULE before including orbitersdk.h, since the preprocessor directives are processed in only one pass.
Remove stdafx.h and turn this feature off (project properties).
You don't need to implement the destructor if you're not using it.
Commenting out code is asking for trouble. It gets too cluttered and hard to read.
It seems you're prototyping the methods and implementing them inside the class. I don't know if this is a problem, but try to implement them outside the class if you have them prototyped. Also, prototyping in C++ is not a requirement like is in C, so no need for header files.

 

[Zatnikitelman]

I've killed off stdafx.h, defined ORBITER_MODULE before including orbitersdk.h, but I'm still getting weird errors:

[MeDiCS]

Seems you have a missing ';' or '}'. Also, #include <string>.

 

[tblaxland]

The class definition is not closed out after _SSM::clbkSaveState. Add an extra '}' after that function.

 

[SiameseCat]

It looks to me like you're declaring member functions within the constructor.

 

[Zatnikitelman]

Yep, that's what was happening, I moved the declarations outside of the constructor and into the class and those errors went away.
But now I have 79 others all related to linking. I hate to post my entire code again and errors again, but I'm not finding any easy solution.

It looks like orbiter.lib and/or Orbitersdk.lib are not being linked in. Check your "Additional Library Directories" and "Additional Dependencies".

 

[Zatnikitelman]

Ok, that sort of worked, got rid of those 79 errors, but now it appears that something is being defined twice and the compiler doesn't like it.
Same code, but new [shorter] error log.
I tried ignoring the MSVCRT.lib, but that gave me more errors.

YAY! It compiled! Sort of. It compiles successfully when I have it set to debug, but when I set it to release mode, it fails and says:

Is there something I missed setting up the project?

BTW-the error from above was evidently caused by defining ORBITER_MODULE before including orbitersdk.h.

You need to change the same settings in release that you had to change in debug. The settings are not automatically copied.

YES! THANK YOU HIELOR!! I now got my first self-coded .dll vessel into the game! It's not much (as you can see from the code above) but that's what's great about saving code
THANKS EVERYONE!

:speakcool:

Just remember to only publish the "Release" version to other people, since the "Debug" version won't work on their computer unless they have VS installed.

 

[Zatnikitelman]

Ok, got another question, not as major and I can work around it but still...
Where can I define my variables? Right now I have the fuel, ISP, and thrust numbers defined and initialized under the setclasscaps method. I've tried moving them into my class, but I keep getting errors. I know in C++ there's only certain places where you can define variables particularly constants. I want the data to eb accessible by other methods possibly, but right now the data is limited by scope from what I understand.

 

[computerex]

In order to make the variables visible to other methods, you can declare them in global scope. However the issue with this is that Orbiter loads only one instance of your dll module through a simulation session, which means that global data is shared through all the instances of your vessel. Define the global constants inside the header of your vessel class, before the class declaration. Define variables specific to your vessel inside the class itself.

public data is visible to the entire external environment as long as an object of your class is instantiated. static data can be used even without instantiation, and private data is only visible to methods of your class.

 

[tblaxland]

I think Zat wants variables to be visible to other member functions in his class (but not outside the class nor to other instances of the class). In that case, declare them in the private member section of your class declaration. Because you are not declaring the class in a header file, you will need to make sure the private section is above your public section and the variable declarations are above any private member functions.

 

[computerex]

Because you are not declaring the class in a header file, you will need to make sure the private section is above your public section and the variable declarations are above any private member functions.

Can you elaborate on that? I wasn't aware that there were restrictions as to where methods/fields are declared inside the class.
