In terminal i've installed cmake and build OpenCV. When i'm typing ls /usr/local/lib i've got a lot of files .dylib
I have to link the .dylib files provided by OpenCV into project
I need to link framework in my project. I open Command line tools (by Add Files to "...") and text in /usr/local/lib. And there are no .dylib
Tell me somebody what's wrong
Thanks !!!!
Your Xcode project is configured to build against an SDK. The the OpenCV libraries are not part of the SDK, they're installed on your system. Switch your Xcode project to using a "Base SDK" of "Current OS X" and the problem should go away.

I'm attempting to use OpenCV in Xcode. I've installed OpenCV 2.4.12 using Homebrew. The associated files are located in /usr/local/Cellar/opencv.
In the documentation I am instructed to add "opencv2.framework" to my project as a binary library. There is no opencv2.framework file anywhere in my opencv directory.
Do I have to make the .framework file or something?
Explore /System/Library/Frameworks for examples on your OS X system. These are bundles containing headers and the compiled framework binaries. If you don't have a .framework directory in the OpenCV resources that you installed, perhaps you installed the source code and you have to build the framework.
The extremely helpful guidelines posted at http://www.vtk.org/Wiki/Cocoa_VTK and via the readme file by Sean McBride and Mike Jackson inside the VTK repo were slightly out of date for VTK 6.1. So in case this helps anybody, I'm posting instructions for installing VTK 6.1 on OSX 10.8 with support for the SimpleCocoaVTK Xcode project.
* Installing VTK 6.1 for OSX 10.8 with Cocoa support *
These instructions slightly modify Ryan Glover's instructions at http://www.vtk.org/Wiki/Cocoa_VTK and the README.rtf in the VTK/Examples/GUI/Cocoa/Documentation folder by Sean McBride and Mike Jackson.
Clone the VTK git repo into a directory of your choice:
cd /Users/you/
git clone https://github.com/Kitware/VTK.git
cd VTK
git checkout tags/v6.1.0
make a build directory
mkdir VTKBuild
cd VTKBuild
Run the VTK cmake script
You will now be inside /Users/you/VTK/VTKBuild, run cmake from here (using the parent directory's CMake files):
cmake ..
Edit lots of lines in the newly generated CMakeCache.txt (in the current VTKBuild directory). One issue I had was that there were error if I didn't use a full path for the CMAKE_INSTALL_PREFIX. So make sure to use "/Users/you/" instead of "~":
CMAKE_INSTALL_PREFIX:PATH=/Users/you/VTK/VTKBuild
BUILD_SHARED_LIBS:BOOL=OFF
CMAKE_BUILD_TYPE:STRING=Debug
VTK_USE_SYSTEM_ZLIB:BOOL=ON
CMAKE_OSX_ARCHITECTURES:STRING=i386;x86_64
CMAKE_OSX_SYSROOT:STRING=/Applications/XCode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk
Compile the VTK project (this might take over an hour to run!):
make
Copy headers to an include directory:
make install
VTK should now be completely installed in the VTKBuild directory and ready to use in an XCode project!
Go to your finder, navigate to Users/you/VTK/Examples/GUI/Cocoa/ and double click to open SimpleCocoaVTK.xcodeproj in XCode.
In the XCode menubar (at the top of the screen) Go to Preferences->Locations->Source Trees and use the + button to add in two source trees:
vtk-debug-include vtk-debug-include Users/you/VTK/VTKBuild/include/vtk-6.1
vtk-debug-lib vtk-debug-lib Users/you/VTK/VTKBuild/lib
Click on the XCode project and delete all the references to vtk 6.0:
In the project view, select Targets->SimpleCocoaVTK and then press "Build Phases" and then open the "Link Binary With Libraries". Delete all the files that begin with "libvtk" and end with "6.0.a"
In the file view of the SimpleCocoaVTK project, hightlight and delete all the files in the vtk-libraries folder.
Make sure the XCode file view is active. Then in the finder, navigate to /Users/you/VTK/VTKBuild/lib, and select all the files that begin with "libvtk" and end with "6.1.a". Drag these files into the folder "vtk-libraries" in the XCode file view.
In XCode, do a Product->Clean
You can now build and run the sample SimpleCocoaVTK project.
I also had to set
VTK_WRAP_PYTHON:BOOL=ON
in CMakeCache.txt
It depends on what user you are too on your machine (computer) and the permissions relevant to that user. I did a find and replace on the CMakeCache.txt file and changed all /usr/local references to /Users/myusername/Develop/VTKInstall. That way everything's at your fingertips and you don't have to change permissions on things.
When you open up the Cocoa example make sure to set in you preferences these paths (e.g. Preferences->Locations->Source Trees). Also you'll need to re-import your vtk-libraries into the project.
I'm running Yosemite with XCode 6.1.1. I hope this helps someone!
If you get error messages likes this, when trying to build VTK:
#error: garbage collection is no longer supported
make[2]: *** Rendering/OpenGL/CMakeFiles/vtkRenderingOpenGL.dir/vtkCocoaRenderWindowInteractor.mm.o] Error 1
make1: *** [[Rendering/OpenGL/CMakeFiles/vtkRenderingOpenGL.dir/all] Error 2
You need to remove a flag in the source CMakeLists.txt:
#IF(APPLE)
SET(VTK_OBJCXX_FLAGS_DEFAULT "-fobjc-gc")
SET(VTK_REQUIRED_OBJCXX_FLAGS ${VTK_OBJCXX_FLAGS_DEFAULT} CACHE STRING "Extra flags for Objective-C++ compilation")
MARK_AS_ADVANCED(VTK_REQUIRED_OBJCXX_FLAGS)
ENDIF(APPLE)#
Either outcomment or delete it all together. Then run cmake again in an empty build directory. Check in the generated CMakeCache.txt in your build directory if it contains a key like VTK_REQUIRED_OBJCXX_FLAGS, it shouldn´t, try running cmake in an empty build directory again.
This 'bug' maybe fixed in future VTK versions.

I have a xcode project that was created for osx snow leopard. All it was required to be built was to run
xcodebuild
from the command prompt. I am now trying to build the same project on OS X 10.7 and the following error happens when I run the same command
/Users/repo/trunk/main.c:31:10: fatal error: 'stdlib.h' file not found
What exactly is going on? I tried to follow the instructions from this question but stdlib.h is still missing.
How can I fix this problem?
Likely you are getting bit by the repackaging of everything inside /Applications/Xcode.app starting with Xcode 4.3. In Unix-like installations stdlib.h usually lives in /usr/include and your project likely expects it to be there as it was pre-Xcode 4.3. You can fix this by installing the command line tools, which includes the tools and the associated headers and libraries in their standard location.
The easiest way to install the command line tools is from inside Xcode. In the Xcode Preferences select the "Downloads" pane and then the "Components" tab. Push the "Install" button next to "Command Line Tools".
You need to run xcode-select to tell xcodebuild and xcrun which Xcode you want to use.
See this manpage.
I'm trying to distribute my app's dependencies with the app.
I've got the macports packages librsvg, boost, and cairo installed 64-bit-only on my Snow Leopard system. When I create an .app bundle of my program, it does not work on machines without macports and the relevant libraries installed because they are not included with the app, which searches for the libraries in /opt.
I have tried the --static flag for static linking, but that caused libcrt0 errors.
What's the best method for linking MacPorts libraries and their dependencies to an OSX application suitable for lone distribution?
You'll want to copy the libraries into your application bundle, using a Copy Files Build Phase. dylibs should be put in the Frameworks directory in the app bundle. You'll also have to add the libraries to your Xcode project.
Try using py2app to create a stand-alone app.
I had to just do this for jsoncpp. What I did was I went to linker settings under the project > Build Phases > Link Binary With Libraries then used the add other to go to my library's path and add the library from the folder which would be under opt/local/lib in the default setup for macport
getting the header files was a bit more complicated. In this case I had ended up going to usr/Include finding the file/folder with the headers, copying it into my project and in the cpp file I added the include line with quotation marks ("")
e.g., moved /usr/Include/json directory into the RestTemplate Project folder using copy. then added to main.cpp
#include "json/json.h"
I am very new to Mac.
I downloaded QT SDK Mac Open source (http://get.qt.nokia.com/qtsdk/qt-sdk-mac-opensource-2010.02.dmg) and installed the Package.
I can run qmake, build samples and run demos,
but I cannot run configure (in order to build the Qt libraries statically).
It says: -bash: No such file or directory.
Documentation says I should run this in the "Qt root folder", but what is this folder in Mac?
I looked for it in /usr/bin, /usr/local/Qt4.6, /Developer/Tools/Qt.
Anyway, what is "configure" on Mac. is it an executable or a script?
Thanks a lot
The SDK download is a pre-built binary library. You need to download the source code version of Qt to be able to configure it to build as static libraries.
The configure script only comes with the source code download version.
I think the SDK only provides the headers and libraries hence the reason you can build applications using Qt. To build Qt itself you will need the source package which is a different download.
