Error: L6218E: Undefined symbol cvWaitKey (referred from main.o)

Cristian CLC

Hi everybody, i am trying to use the OpenCv's libraries with keil and i ve done this:
1. Added a Group called libs where i ve put al the .libs files
2. In the project configuration added all the necesary include paths ( and even more just in case ). libraries, sources, and .h paths

I have created a simple project, which compiles and works perfect without using Opencv libs

But when i try to use this libs i get this error:

Error: L6218E: Undefined symbol cvWaitKey (referred from main.o).

(CvWaitkey is defined in highgui.h which is included at the top of the main file)

It seems preety obvious that the compiler doesnt know where is defined cvWaitKey but i dont know what i am doing wrong because i ve ensured to include the highgui.h in the main file and added the include path in the project configuration.

Any idea?

Thanks!

here u have a print screen:

    I realize that this is about 6 years too late for the OP and you all sound very well-educated, so forgive me if this is too basic a suggestion. I had this error and it turned out that not only do you have to do all of the proper "include"s, as in any other C-based program, but you also have to do a Keil include.

    That is, mouse over to the "Project" window on the left-hand side, project -> target -> source group. Right click "source group" and click "add existing files." Filter by file type and add the missing .c file.

    I was chugging merrily along thinking all was well, but now that it's included, I have 30 errors to debug.
