fail to install - cannot find 'cv.h' file #58

Open astelixoose opened 11 years ago

astelixoose commented 11 years ago

Hi,

When trying to install opencv, getting an error :

screenshot_1

This is problem with include path, but i have no idea how fix it. Please help.

penguin359 commented 11 years ago

This is just a front-end to the actually OpenCV library, have you built and installed that yet?

astelixoose commented 11 years ago

I have installed OpenCV library, but i dont know if it's correctly. How can i check it ?

Installed:

Can you post the output of pkg-config --libs opencv and pkg-config --cflags opencv? For --cflags, you should see something like -I...\include\opencv and if you look inside that folder, you should find cv.h.

Seems like pkg-config is looking into C:/opt/gtk instead of the prefix that you have defined in "opencv.pc". Maybe he isn't reading the right file. Did you set an environment variable PKG_CONFIG_PATH to the location of "opencv.pc" file and add it to the systems path ?

astelixoose commented 11 years ago

He is reading the file. These are results "pkg-config --debug opencv"

Path position of 'OpenCV' is 1
Adding 'opencv' to list of known packages, returning as package 'opencv'

I have set the environment variable: 

PKG_CONFIG_PATH - C:\opt\gtk\lib\pkgconfig

This is the problem:

Variable declaration, 'prefix' overridden with 'C:/opt/gtk'

but i dont know why

System path is:

path - (...);C:\opt\gtk\bin\;%OPENCV_DIR%\bin;C:\Python27;(...)

In the location "C:\opt\gtk\bin\" i have pkg-config.exe

penguin359 commented 11 years ago

Don't know why, but it seems to be grabbing the prefix from the lib/pkgconfig folder location. Is there a lib/pkgconfig under the OpenCV folder? If there is, can you point PKG_CONFIG_PATH there? If there isn't, can you move /lib/pkgconfig there and update PKG_CONFIG_PATH?

penguin359 commented 11 years ago

Sounds like this is standard behavior according to http://mingw-users.1079350.n2.nabble.com/pkg-config-overrides-prefix-td7578195.html. Two possible solutions, add --dont-define-prefix to binding.gyp as an argument to pkg-config or move the contents of C:\OpenCV to C:\opt\gtk. It sounds like you have installed OpenCV and pkg-config to two different prefixes, but, since Windows doesn't have a standard prefix for FLOSS, pkg-config tries to help the developer by overriding the prefix found in the pkgconfig files since they are usually wrong on Windows.

astelixoose commented 11 years ago

I moved the contents of C:\OpenCV to C:\opt\gtk.

pkg-config --cflags opencv

All these paths are correct.

Find "cv.h" results:

C:\opt\gtk\build\include\opencv
C:\opt\gtk\include\opencv

Environment variables:

But it still does not work ;(

carthagan commented 11 years ago

It seems that MSBuild doesn't "look" into the includes of opencv. Download the new binding.gyp file, I have fixed it for this case (https://github.com/peterbraden/node-opencv/commit/7ea1435491a754df9e1b4b2ea1b89036bf90983f), or simply add the following lines : ,'include_dirs': [ '<!@(pkg-config --cflags opencv)' ]

carthagan commented 11 years ago

The problem is that there isn't a function called round in the math.h library, so you have to add it :

static inline double round(double value) { return floor(value + 0.5); }

peterbraden commented 11 years ago

Is this a bug in my code? Should I add round? Guessing this is a windows only thing?

carthagan commented 11 years ago

Yeah this is a windows bug. You have to add the round function in Matrix.h !

astelixoose commented 11 years ago

So, i added round function to my math.h:

E:\Program Files\Microsoft Visual Studio 10.0\VC\include\math.h

inline double round(double value)
{
    return floor(value + 0.5);
}

I getting an error from first image when i trying to install opencv. So i installed it from the repo.

git pull
node-gyp rebuild
npm install

I getting warnings only from node-gyp rebuild e.g:

Machiel-B commented 10 years ago

I'm having the same issue. Did you ever find a solution?

tiny-tinker commented 10 years ago

Same here! I've been banging my head on this for a few days now. Anyone have any other suggestions?

Machiel-B commented 10 years ago

I gave up on this. I'm running an opencv python script through a node child process now.

fabiorogeriosj commented 10 years ago

Hi guys, I was facing the same problem last week.

I solved the problem by installing a virtual machine with Ubuntu and installing OpenCV + Node.js it! It worked perfectly!

darioodiaz commented 9 years ago

I have been searching this error and that's because the node version of the compiling fies is different from the node version that "decompile" the .node project

Here the explanation:

https://github.com/sass/node-sass/issues/76

darioodiaz commented 9 years ago

Something weird is I use opencv 2.4.10, VS 10 and node 0.10 and when I try to use detectObject function when the source image isnt have a face the save function works, but when the image has face the save function doesnt work, any idea? I'll compile the node-gyp with VS 12

darioodiaz commented 9 years ago

I do an npm update and when I recompiled the lib I have this issue u.u, why its so complicated? hahaha, trying to find the solution... I think that the node-gyp compile process doenst match with the nodejs import project
