wasn't that fixed already by your patch AF? or is this the other VS version?

That was fixed in the final release mode of the VS7 project.

the other 2 modes, and the 3 modes in the VS8 build still have the issue.

Opening the VSProjects in a texteditor and searching for SDL-1.2.8 and replacing the 8 with a 9 should fix it.

Perhaps the fact you have to extract vclibs to a "vclibs" folder just like I forgot to?


Nah, got that..

I opened it in a text editor but did not find the refference.. are you talking about the .vcproj or another file?

*edit* I did not find it because the file already has .9 in it.

So, um what else could I have fucked up?

there should be 6 references not 1, 2 for each mode, debug, release, and final releae.

Check them in VS too in project settings, additional include directories and additional library directories.

No need to worry I think, MinGW spews out those errors too on linking here and everything seemed to work fine...

As of revision 1544 I get 6 compile errors in VC03, plus 6 of new warnings complaining about inconsistent dll linkage in the AI interface class destructors.

Code:

Add BUILDING_SPRING to preprocessor #defines in build options. It's needed to fix up vtables and AIs and stuff.

That took care of the warnings, but not the errors.

I seriously think this whole vtable issue needs to be solved on GCC/scons only. There are no problems on VStudio with vtables anyway.
(Why should vs need extra defines when gcc messes it up?)

Hi, I've tried compling the source under VS2005 and i get an error about resources.h being missing

It's not there :p

heres the error:

Code:
Compiling resources...
.\rts.rc(3) : fatal error RC1015: cannot open include file 'resource.h'.
Build log was saved at "file://c:\taspring_0.72b1\rts\build\vstudio7\Release\BuildLog.htm"
rts - 1 error(s), 17 warning(s)


if i do a search for "resources" in the source folder, i only get...
\game\gamedata\resources.tdf
\AI\Global\NTAI\resources\
\AI\Global\JCAI\profiles\xta_core_resources.cfg

You should be looking for resource.h not resources.h
I would try replacing the path with ../vstudio8/resource.h

I won't have access to internet until Monday. Good luck.

I get linker errors with current SVN code, with IAICallback, IAICheats, IGroupAICallback, and IGlobalAICallback seeming to have missing virtual destructors - whatever the "DECLARE_PURE_VIRTUAL" is supposed to be, it doesn't work.

Just updated, and tried to compile. Should be the latest. Does number 1558 mean anything? :?:

yes, thats latest.

Guess MSVC doesn't support (pure) virtual destructors across DLL boundaries at all...

I'll just disable them and reintroduce all potential bugs related to them on MSVC (and MinGW as I couldn't get it to link destructors...). Disabling it is easy now I got it all macrofied anyway.

So try again and it should work.

It might be just VC 2003 that doesn't support them, maybe 2005 does.

In any case, it compiled now, thanks.

I thought interface classes shouldnt have destructors, only the classes based on them

No.

If you don't give a class with any virtual methods no destructor, the compiler will generate a non-virtual empty default one.

This means that if you have an interface class 'Interface' and a pointer to an object which derives from Interface, deleting the pointer will NOT call the destructor of your derived class (possible memory leaks), ie.
Code:
class Interface {
  virtual void foo();
}
class Object:public Interface {
  ~Object() { delete[] data; }
  unsigned char* data;
}
// in a function:
Interface* p = new Object;
delete p; // <-- memory leak ~Object is not called, so data is not deleted


I now (or since a while actually) realise spring was working around this by C style casting the pointer p back to Object*, and then deleting it (in AIs).

This happened to work, but it would silently break and crash hard in case you'd ever use multiple or virtual inheritance.

It'd also leak memory/crash in case you'd set up your AI in certain ways, like having a common CMyAI class (implementing the core of your AI) deriving from IGlobalAI and separate derivatives of CMyAI that specialize it for e.g. metal maps, water maps and normal maps, or different mods.
