Topic: To write plugin with Dev-C++ ? - Page: 1

Hello,
Can you write plugin with DEV-C++ compiler ?
The My_plugin.cpp example does not Work for me.
Here the log of compilation :

Compilateur: Default compiler

Can you help me ?
How to configure DEV-C++ ?
Thank you.

I'm looking for a solution with dev-c++

Otherwise, there is no problem with dev-c++ and video plugin (effect + transition) whereas the idea of the SDK is the "same", i mean same COM , same idea of class so it should work with normal plugin too

Maybe Dev-C++ doesn't like "enum" ...???
 
what ?
 
Yes after testing, Dev-C++ seems not to like the keyword "enum" in the SDK (vdjdsp2.h) that's why it writes these errors. The error with the function OnNotify() is due to the param "enum ENotify"
 
Did you find a solution to bypass this dev c++ behavior ?
 
Unfortunately no
The fields of each enum equals to integer so i'm going to try by changing enum to int
If you have an idea, i'm open
 
looks like it has something to do with casting. Will test...
 
If you delete the enum in the .h and replace all call by the corresponding number (the first is 0 as writed).

Shouldn't it work?
 
I tried to use the integer but without success

So to sum up: to disapear the errors of the compilator, delete in the .h:

* in the declaration of structure,class, enum:
//------------------------
enum EProcessingType;
enum EInterfaceType;
enum ENotify;
//----------------------

* in the class:
//------------------
virtual HRESULT __stdcall OnNotify(ENotify notify,int param1,int param2) {return 0;}
//--------------------

But unfortunately the plugin doesn't work in VDJ with that (VDJ writes "(empty)" )!!! I really think the main problem is in this declaration of enum as without this declaration dev-c++ recognizes the difference of data type The dll is well built as it works for video plugin
 
did you try to replace

virtual HRESULT __stdcall OnNotify(ENotify notify,int param1,int param2) {return 0;}

by

virtual HRESULT __stdcall OnNotify(int notify,int param1,int param2) {return 0;}

?
 
Only by changing what you say Kaleo (i mean i let the enum declaration), i get:

In file included from Simple_Mix.cpp:3:
vdjdsp2.h:27: error: use of enum `EProcessingType' without previous declaration
vdjdsp2.h:28: error: use of enum `EInterfaceType' without previous declaration
vdjdsp2.h:29: error: use of enum `ENotify' without previous declaration
 
I think dev-c++ doesn't like the declaration of enum without including definition at the same time that's why it writes that.
 
LOL, of course, you need to delete all ENUM declaration and try to replace enum parameters by int as I suggest previously.

But I don't know if this will work as I don't have Dev-C++
 
Even with the int everywhere (i had tried before), it doesn't work: the provided interface is not created (even the name of the plugin doesn't appear in the slot :-( as the struct doesn't work too). You should personnaly try i think

I tried too:
/////////////////////////////////
#define PROCESSING_NONE 0
#define INTERFACE_PROVIDED 0
typedef int EProcessingType;
typedef int EInterfaceType;
typedef int ENotify;
////////////////////////////////
 
HI guys, finally i worked till late night and I managed to
compile polarity with dev c++.

I tried changing enum to int, replacing many things and finally the solution was simple.

You just have to move the enums BEFORE using them in the .h file.
----------------------------------------------------------------


I uploaded the whole project to the SOURCES as a zip file.

The plugin is stripped off buttons and images, so only thing it makes is iverting the right channel's polarity/phase.

I was worried that i have to buy Microsoft's stuff when my VC 2005 beta expires :-)

I hope there will be less problems with devc++ in the future.


As there are no changes (except changing order of lines) in the .h file it could be nice if the moderators could update the .h file provided in the developer section.

(or feel free to provide there this example project directly)

or lower the minimal requested level
 
Strange behavior, the class should not by compiled so this error should not be...

Neverstheless, no problem to swap lines.

Thanks lopez453
 
So now, more people can try to create plugins.

Whooaa, looking forward for a dozen new :-).

Come on dudes, don't hesitate. Give making plugins a try....
 
Yes!! :)
 
I tried to use the SDK files to modify the existing cut transition to cut sooner than the mid point for scratching. I used the Dev-C-++ program and tried to follow the limited steps given on the forum. I go to compile and gives this error. (the name I named the project was scratch-cut)

[Build Error] No rule to make target '"my', needed by 'scratch-cut.dll' Stop

What am I doing wrong?
 
First don't write "scratch-cut.dll" but "scratch_cut.dll" then i don't have enough information to help you
