I have followed the following steps to install opencv on my mac. But I am getting a 'Build Failed' message.

What is the solution for this ?


Steps that I have followed:

  1. Create a New Folder OpenCV in Desktop Working Directory.
  2. In Terminal cd /Users/administrator/Desktop/OpenCV
  3. In Terminal git clone https://github.com/Itseez/opencv.git

This results in the cutting edge OpenCV from GIT repository

  1. Now install CMake software
  2. In Terminal cd /
  3. In Terminal sudo ln -s /Applications/Xcode.app/Contents/Developer Developer
  4. In Terminal cd /Users/administrator/Desktop/OpenCV (open working directory)
  5. In Terminal python opencv/ios/build_framework.py ios

Result of this is the build failed message.

The following build commands failed:
    Libtool /Users/administrator/Desktop/OpenCV/ios/build/iPhoneSimulator-i386/modules/world/UninstalledProducts/libopencv_world.a normal i386
(1 failure)
Traceback (most recent call last):

Did you ever figure this out?

Same here. Actually there is a build failure way before the lines you posted.

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't open file: /Users/christophkapffer/_privat/ios/build/iPhoneOS-armv7/3rdparty/libjpeg/OpenCV.build/Release-iphoneos/libjpeg.build/Objects-normal/armv7/jmemansi.o (No such file or directory) Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool failed with exit code 1

That is the reason why the libtool can't merge the different builds in order to create a universal framework. There is no install directory for iPhoneOS-armv7, because that build failed in the first place (see above).

Just to extend my previous comment: The file 'jmemansi.o' is missing for all three platforms (armv7, armv7s & i386).

yes, that's the last error you get. And what's the first error/message/sugestion in clean python run? Messed C compiler? ;-)
