Problem with opencv library (fatal error : No such file or directory)

[Zekk]

Hello everyone,

I want to use opencv library (v.2.4.5) with C::B (v.12.11) I have followed the instruction bellow (http://opencv.willowgarage.com/wiki/CodeBlocks), and I also set the PATH variable environnement on this adress : C:\opencv\bluid\x86\mingw\bin (my opencv library was extract in C:\).

But when I try to test a sample program like  "demhist" in the folder "C:\OpenCV\samples\cpp\demhist.cpp", I have the following message : fatal error : imgproc.hpp : No such file or directory

I'm looking for a solution since yesterday but I can't find anything.

Do you have any suggestions ?

[BlueHazzard]

have you done step 3 to 6?

[Zekk]

yes, I even try to uninstall/reinstall Code Blocks and restart the steps

[BlueHazzard]

search for the  improc.hpp  and add the the path to the search directories....

[Zekk]

They are two files  imgproc.hpp.

The first is in C:\opencv\build\include (I already add this one)
The second is in C:\opencv\module

Even if I add the  adress in Search directories (Compiler), it's still not work

[scarphin]

How do you include 'improc.hpp'?

Code Select Expand

<improc.hpp>

or

Code Select Expand

<opencv2/improc/improc.hpp>

[Zekk]

I include 'imgproc.hpp' with :

<imgproc.hpp>

I already try with

<opencv2/imgproc/imgproc.hpp>

but it doesn't work.

[BlueHazzard]

Did you made a project, or did you loaded only the source file?

try to: Project->Build options->Other Options, add there a -v and rebuild. Then post the FULL BUILD LOG, from the "Build Log" tab here.

greetings

C:\Users\Clems\Documents\Programmation\test_opencv\main.cpp:9:23: fatal error: imgproc.hpp: No such file or directory

so, is this header called "imgproc.hpp" or "improc.hpp"

check your typo....

[Zekk]

Ho ok, I'm sorry ... wrong writing. I corrected my previous topics : the right name is "imgproc.hpp"  as you said (but problem remain the same).

Sorry for that.

[scarphin]

What directories do you have in your 'project->build options-> search directories->compiler' for top level?

[Zekk]

I have nothing.

When I read your anwser, I try to add in  'project->build options-> search directories'  the same things than in 'settings ->compiler ->search directories', but I still have the same error.

[scarphin]

Did you actually performed the steps in http://opencv.willowgarage.com/wiki/CodeBlocks? Because if you did you would have your search dirs in 'project->build options-> search directories->compiler'!

And again, what directories do you have in 'settings ->compiler ->search directories' or wherever you have them?

[stahta01]

Please decide what MinGW GCC you are trying to use!
Then, tell us which one you are trying to use?

You appear to be trying to use two different MinGW GCC in a single project this will NOT work!!!

One of them.
