On OS X, we're gonna wanna make surewe have Xcode installed.We can get Xcode for free from the Mac App Store.Xcode will install most of the toolswe need for this course, except for CMake.We want to use CMake to help us in cross compilingour code and making sure that our project files arepointing to the right libraries.CMake is a great tool for writing code that willwork across different platforms.I like building CMake from source,so on the CMake website,let's download the Unix/Linux Source tar files.
Once they are downloaded,cd into the CMake file directory.Here we can typedot slash bootstrap && make && make install.Depending on your user permissions,you may need to write sudo make install.This will build, compile and install theCMake command line tools onto our OS platform.With CMake installed, we can cd intoour exercise files folder.
This utility will generate the entire database code for Android and iOS from a specified.xml file. The code is written in C++ and requires a C14 compatible compiler. Simple Makefile also included for Linux/Mac. We have also included CMake compatibility and Visual Studio has builtin CMake capability.
Where we are gonna do here is useCMake to generate an Xcode project filethat contains all the lessons for this course.Let's make an Xcode directory,cd into the Xcode directory and typecmake space dash capital G for generate spaceXcode in quotes capital X lower-case c o d espace dot dot and hit return.
What Cmake Do I Download For Mac Free
Cmake is now generating an Xcode project file for usthat points to the correct librariesand include header files.If we look inside of our exercise files folder,we see our Xcode directory,and the Xcode project that CMake has generated for us.Let's open that.In our project hierarchy we have all the example filesthat we're going to be looking at throughout this course.We also have some of the demos that comeincluded with GLFW, the windowing library.
To follow along with the lessons,open the folder that corresponds to the lesson name.In the Source Files directory,we'll find our dot cpp filesthat correspond to the current lesson.To compile all the current lesson,navigate to the list of targets,select the target and build that.My Xcode project will look a little different.The name of my Xcode project will beat the top of the screen,corresponding to the current lesson.
In the file hierarchy on theleft-hand side of the screen,the name of the current lesson alsocorresponds with the name of the project.So in your Xcode project file,which includes all the lessons in one project file,just make sure that you are in the same folderas the name of the current lesson,and you should be able to follow along.

How to use cmake on Mac? Let's say I have a project in Xcode and I want that project link with assimp library.
So I download assimp source, generate build with cmake, point Xcode to /include in downloaded source and what then? Where are built libraries?What I only have is Xcode project of that library. Does it generate libraries?

If I use brew to install assimp, I only set this in my Xcode project:
and I'm finished.
What Cmake Do I Download For Mac Download
Halo 3 download for mac. What are benefits of cmake for building libraries from source besides that source is 'fresh' and I'm unable to do it right?
Could somebody post step-by-step what to do when building things with Cmake, with explanation?
Most importantly where does Cmake put libraries, and how to link with them?

CMake does not build the libraries, it 'only' generates platform specific Makefiles (or equivalents).You still need to compile and install the compiled libraries and headers.
For the library you want to build the following steps are necessary (I am doing them on Linux, but this should be applicable to Mac OS X as well).
The
build folder now contains a Makefile , and when you run make , the library will be compiled.
After this step, the freshly built library is located at
build/code/libassimp.so .
You could leave the library as well as the include files there and reference them when compiling/linking your project. Usually, you want to
install them, so they are available systemwide and can be found automatically.
This is done using
sudo make install .
The library should now be in m.s.m.s.
/usr/local/lib , the include files in /usr/local/include . You can change these locations using CMake.
