Error installing on MacOS 10.12.6 about opencv4nodejs

[justadudewhohacks]

@muhammadsamir11
Did you get this error from npm install? I think your error is not related to this issue, could you open a new issue and append the npm log?

[carlosen14]

Ok, i ran and all the examples worked just great!
Great job you made and thanks for your help! ..

PD: simpleTracking1.js example just didn't work, but thats another topic..

[carlosen14]

Same result with npm install --save opencv4nodejs

[justadudewhohacks]

Since it tries to compile the Tracking module, I assume you have set up the opencv-contrib module. Can you tell me which OpenCV version and which contrib version you are using. I only tested contrib3.2 so far.

[carlosen14]

How to know which version of contrib am i using?, I don't remember i have installed this extra module.

[carlosen14]

if i don't have it, i have to reinstall opencv from source, right?

[justadudewhohacks]

The contrib module is not required, the problem is probably, that you have libopencv_tracking.dylib in your lib folder which does come from a opencv-contrib version other than 3.2. The install script notices this lib and compiles the npm package with contrib. A dirty fix could be to simply rename that dylib. Optionally you can also go in to the opencv4nodejs folder in node_modules and check lib/utils.js. At the top there are arrrays defined for which modules to search for installation. You could try to simply uncomment the tracking module in xmodules. The last option would be to uninstall the contrib module altogether from you system.

[justadudewhohacks]

Just noticed it should also be possible to simply rename or remove the tracking.hpp from the opencv2 include dir.

[carlosen14]

These method of rename tracking.hpp did not work. These files, because there are two, are inside the test folder, i don't think this would work when installing with npm install.

i'll try the other method.

Did reinstall OpenCV w/ contrib from brew, and still get the same error..

brew install opencv3 --with-contrib --with-python3

brew info opencv3 shows other options.

Any other idea solution? or if you need more info..

UPDATE
Did figurated

Warning: opencv: this formula has no --with-contrib option so it will be ignored!

So i am where i did started.

Did reinstall OpenCV w/ contrib from source following this tutorial

https://docs.opencv.org/trunk/d7/d9f/tutorial_linux_install.html

got this error now..

Sorry for inconvenience, this seems not to be related to contrib directly. It seems to be an osx gcc issue. I provided an quickfix which should hopefully fix it, if you want to try it again.

Otherwise I will try to figure it out asap.

[carlosen14]

I tried to install both ways npm i on downloaded zip from git, and npm i -g opencv4nodejs and both gave the same result.

I'll insert full trace at the end but this seems the error is the cause also it appears 5 times in similar ways, did I missed a library from opencv when reinstalling?

I tried to build the package for contrib versions other than contrib3.2 now and indeed the build fails. I disabled the tracking module in the default build for now until I added support for other contrib versions. You should be able to build the package now.

Thanks for reporting this issue and for your patience.

[muhammadsamir11]

I have this error can you help me to fix it please.

clang: error: no such file or directory: 'app/node_modules/macro-inferno/src'
make: *** [Release/obj.target/opencv4nodejs/cc/opencv4nodejs.o] Error 1

[carlosen14]

Ok it looks it is installed now, i haven't tested yet, but this is the log..

First i ran npm i -g opencv4nodejs and it was weird because it throws an error Error: Cannot find module 'nan'..
Ok, installed using npm i -g nan and it was installed fast.
Then i ran again npm i -g opencv4nodejs and this time also throw a lot of warnings about comparing 'int' and 'uint32_t' also 'int' and 'size_type' but after all this it was installed without errors

SOLINK_MODULE(target) Release/opencv4nodejs.node
clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]

  added 3 packages in 108.23s

I'll test the lib and comment back

[justadudewhohacks]

Great to hear, that it works now.

[justadudewhohacks]

Thanks for reporting the bug in simpleTracking1.js, I fixed it.

[muhammadsamir11]

@justadudewhohacks
It works fine
