Re: Download Xcode For Mac
Micael Bourdette
I am a Ruby on Rails Developer and already have Xcode (command line tools) setup/working on my Mac. I have a ton of existing dependancies with Xcode. when I try launching Unreal Engine 5.2 I get the error:
Xcode Not Found - Unreal Engine requires Xcode to compile shaders for Metal. To continue, install Xcode and open it to accept the license agreement. If you install Xcode to any location other than Applications/Xcode, also run the xcode-select command-line tool to specify its location.
Had the same issue. In my case it triggered after installing homebrew (with which I tried to install an alternative java version) which installed some command line tools of its own. I first reinstalled Xcode to no effect. Then I closed both Epic Launcher and Xcode and ran the command and now projects open just fine.
It was simply solved when I installed Xcode from App Store and opened it the first time and agreed the terms and licenses of Xcode. Then, I reopened the Launcher and launched the Unreal Engine again. It worked!
First, extract the folder you downloaded from this website and put it somewhere convenient. This folder will be referred to as your openFrameworks root folder (also known as OF_ROOT). Here's some of the key subfolders inside the openFrameworks root folder:
The file with the .xcodeproj extension is the file you should open in Xcode. Open it now and you should see something similar to the following. You may need to expand the project in the left bar and drill down to the ofApp.cpp file as shown in the image below in order to see anything interesting.
The bar on the left is your general purpose project browser (1), which will show your project's files (if the folder icon is selected at the top), as well as errors that crop up while trying to build your app (2) (the triangular icon).
In the middle is your main editor (3). It will show you an appropriate editor for whatever file you've selected in the project browser. This is usually a text editor for source files (.cpp and .h files), but will show you your project's settings if you select the project file at the top, or will let you examine image / video / sound files as well.
The first time you compile an openFrameworks project, it will likely take a minute or so as openFrameworks gets compiled. This usually only needs to be done once, unless you update openFrameworks or edit any of its internal files. After openFrameworks itself is finished, Xcode will compile the example and you should see a "Build Succeeded" message and a window with the example app happily spinning away.
After closing the example, you may see a new panel open at the bottom of the Xcode window. This is the console where ofLog messages will show up, as well as another panel which is used for debugging. You can show and hide this panel with cmd-shift-y.
Now that you've verified your setup, it's a good time to start a new project from scratch. In the projectGenerator folder, you'll find projectGenerator.app which will make it easy to create new openFrameworks apps.
Afterwards, close the project generator and navigate to the apps/myApps/myProjectName folder. Open myProjectName.xcodeproj in Xcode, expand the project in the browser on the left, expand the src folder and select the ofApp.cpp file.
As your project grows, you'll probably want to start adding new files. These files might be ones written specifically for your project, or they could be addons or external libraries other people have written.
In the dialog that pops up, navigate to macOS -> Source and then select C++ file. Xcode will create a .cpp and .h pair for you automatically, so just give it a base name ("myNewClass") and let it do the rest.
If you are sure that the addon is working properly, you can try to compile your application using the older "Rosetta" architecture. Some of the libraries need to be compiled for Apple Silicon Processor (arm64 architecture) to run efficiently on new Macs. But you still use these libraries even if they are built for Intel-based Macs by switching to the Rosetta mode;- Open XCode- Open your oF project- Goto the top menu -> Product -> Destination Architecture -> Show Rosetta Destinations - Hit run again.
There can be several reasons of your app getting slow down. Before asking in the forum you give a try the following tips;- Try commenting out console output messages in update() and draw() functions have such ofLog(), ofLogNotice(), ofLogVerbose(), cout, etc... commands.- Try to run the app in Release mode
Position-independent code (PIC) can be boundto any address in a program without requiring relocation by the link editor.Such code is inherently sharable between simultaneous processes. Thus, ifyou are building a dynamic, shared library, you must compile the componentroutines to be position-independent by using the -xcode compileroption.
In position-independent code, each reference to a global item is compiledas a reference through a pointer into a global offset table. Each functioncall is compiled in a relative addressing mode through a procedure linkagetable. The size of the global offset table is limited to 8 Kbytes on SPARCprocessors.
