Plugin Question

20 posts in this topic

I am trying to work on a few AutoIt plugins. I am a bit confused with the example.c file that came with the Plugin_SDK.

BTW Thanks to everyone who had a hand in the Plugin architecture.

The problem I am not understanding is the fact that AU3_SetString(pMyResult, "Hello World"); Sets the result?

I have never created a .dll file so this is all really new to me. Not to mention my C++ skills arent the greatest. I am just trying to learn.

Anyone that can offer some assistance, it would be greatly appreciated.

Okay I think I have figured out my above question, but now when I compile I am getting the following error.

Below is the code that is having the trouble with the compilation errors. (au3plugin.c)

void AU3_FreeVar(AU3_PLUGIN_VAR *pVar)

{

if (pVar == NULL)

return;

AU3_ResetVar(pVar);

free(pVar);

}

does it matter that you have a return statement in functions that are declared as void? Edited by cameronsdad

How else would you get out of the function pre-maturely? Notice the function isn't returning a value. If it was returning a value, that would be a problem.

i'm not really up on my C or C++, i just seem to remember having issues with returns in methods declared as void in java. As far as exiting prematurely, seems like:

void AU3_FreeVar(AU3_PLUGIN_VAR *pVar)
{
if (pVar != NULL)
{
AU3_ResetVar(pVar);
free(pVar);
}
}

would achieve the same result right?

Right, it is. However, in large or nested code structures, that may not be usable. Using the return keyword with no argument is valid in a void-returning function.

cool, yeah i wasn't sure but thought it might have had something to do with the errors:

../Plugin_SDK/src/au3plugin.c:30: error: invalid conversion from `void*' to `AU3_PLUGIN_VAR*'

definitely not the first time i've been wrong, and i'd bet it won't be the last...

code compiles fine under VS. the problem must be with GCC.

Hrm... Okay. I guess I should go back and see if the Dev's C++ example compiles.

Okay... the example that came with the plugin_sdk compiles perfectly under Dev's C++. So now my issues are as follows.

I am trying to compile as C++ is that a problem? I noticed the Plugin_SDK is being compiled as C.

I did notice in the example Dev file the compiler options and such were set, so I copied and pasted those.

I am still not able to get this to work. I am having a different set of errors now.

If anyone has any suggestions comments please let me know. I need help on this.

Well I finally got it to compile. Not sure how this is going to work, because I had a bunch of linking errors. I am unsure why. It is in relation to all the AU3_* functions.

Can someone please help?

Hmm, some bugs in au3plugin.c. I'm suprised that no warnings were given when I compiled, but might be the settings I used.

The first error you posted on line 30 was in the line:

AU3_PLUGIN_VAR *pVar = malloc(sizeof(AU3_PLUGIN_VAR));

All mallocs should be casted to avoid those error. eg.

AU3_PLUGIN_VAR *pVar = (AU3_PLUGIN_VAR * )malloc(sizeof(AU3_PLUGIN_VAR));

All the other errors seem to be the same too. Make similar changes.

Excellent. I will give it a shot. Yea your version compiles fine. I am assuming that C vs C++ doesnt really matter right?

Thanks for the help I will see if that fixes it.

Hrm... here is the following errors that came up. I am sorry this is such a pain. I am including a zip file with all files attached. Jon I know you are busy, I really appreciate the time you have spent to read this topic and reply.

Here are the current errors.

Please download the following zipfile containing my entire project.

Edit: I removed everyone but the first cast, and the only problems now are linking errors.

Thanks to everyone who had read the thread.

It's a c/++ problem. They get compiled differently so that c++ functions are confused when calling c functions are vice versa. I'll work around it but the easiest solution atm is to rename au3plugin to .cpp which will force it to compile as c++.

On line 89 the cast should be (char *) btw..

I had set the file to not compile the au3plugin as C++ but as C.

I will try the line 89 deal as well as the .cpp extension.

Your example works perfectly. I just dont understand why I cant copy it.

Thanks again Jon,

JS

That's the problem, all the files need to be compiled with the same. It doesn't matter if they are all c++ or all c but the mixture causes the problem. There is a way around it to tell the compiler how it should "decorate" functions but it involves editing every single function declaration and header so it's easier for you just to make sure that all the files are compiled the same.

Excellent... after changing the file to .cpp, and (of course making sure it was compiles as C++ again), I also set 88, 104, and 132 with the (char *) casting. Thanks it seems to work. Now to test the plugin.

I think I was also having errors with GetInt32, but I just decided to use a string. I am going to put it back to an integer because my second parameter is supposed to be a number.

Thanks for everything Jon,

JS
