Hi,

I've just recently decided to delve into the world of C++ plugin development. I've already made a COFFEE plugin, but C++ seems to be more powerful, so I'm trying to switch over.

Anyway, I'm using Visual C++ 2005 Express Edition, and when I try to 'build' a solution, or compile the whole thing, I get a fatal error:

LINK : fatal error LNK1104: cannot open file 'odbc32.lib'

Now, could this be because I'm using the Express Edition or is it perhaps a common mistake I've made?

Hope you can help me

Hi,

I just got the same problem with 9.521. Hope that someone can solve the problem. I fear, it's an "express" limitation. Since you can download this package for free, it would be toooo easy :-).

You guys probably forgot to download the Platform SDK.

Yep, you're right, I forgot to download the platform sdk, but now that I've done that, I'm getting even more errors. More than 1500 of them.

Any idea what causes this?

The new errors look like this:

Main.obj : error LNK2019: unresolved external symbol "public: int __thiscall GeResource::Init(void)" ([email protected]@@QAEHXZ) referenced in function "int __cdecl PluginMessage(long,void * )" ([email protected]@[email protected])

They're all about 'unresolved external symbol'.

Any help?

It sounds like you're not linking with the SDK project lib files... within your workspace, do you have a project named "_api_v8" ?  if so, set your project's 'Dependencies' to depend on that project.  Otherwise, you'll need to add a lib to your link line (like "_api_v8_deb.lib"... look in the \MAXON\CINEMA 4D R9\resource\_api_lib folder for the appropriate libs).

Well, that might be the problem, but I'm having trouble building the api. Here's what I get when trying to build the cinema4dsdk with the api as dependency:

Now, the errors seem to be about Ngons. Is there any way to fix this?

Yes, default arguments are 'banned' from newer VS C++ behavior. That is, things like this:

void MyMethod(INT value = 0);

where '= 0' is a default-argument value on 'INT value'. You will need to do two things to fix this:

1. In any calls to an SDK method where you have omitted arguments in order to accept the 'default-argument', you will need to put the default value in its place explicitly. i.e.: MyMethod(0).

2. In the definitions of any SDK methods using default-arguments, you will need to remove the '= X'. i.e.: void MyMethod(INT value);

You will probably encounter more of these as you fix others.
