I am using Xcode to build an old code and specify SDKROOT=/Developer/SDKs/MacOSX"${HOST_VERSION}".sdk/
I want to specify SDKROOT for latest SDK that comes pre-installed (?) on the system. e.g. I am on 10.8 already and I want to specify SDKROOT with -syslibroot, but there is no such SDK in /Developer/SDKs/. Should i just ignore syslibroot altogether if SDK_VERSION == HOST_VERSION?
Newer Xcode versions have the SDKs inside the Xcode.app bundle, e.g.
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk
You get the list of installed SDKs together with their path by running
xcodebuild -sdk -version
from the command line.
If you have installed the "Command Line Tools" (Xcode Preferences -> Downloads -> Components) then compiling without "-syslibroot" should be equivalent to compiling against the latest SDK.
See the help to the "Command Line Tools" package:
Downloading this package will install copies of the core command line
tools and system headers into system folders, including the LLVM
compiler, linker, and build tools.
As stated in another stackoverflow question:
xcrun --sdk macosx --show-sdk-path
With xcodebuild -version -sdk macosx10.7 Path you can get the Path to the OS X 10.7 SDK.
You may replace 10.7 by ${SDK_VERSION} or ${HOST_VERSION} depending on your needs.
I know of no command to obtain the version of OS X, which could be used to obtain the Path to the SDK matching the version of OS X currently running.
Note: for xcodebuild to work, the user must have configured xcode-select properly, for example xcode-select -switch /Application/Xcode.app.
CommandLineTools was outdated, reinstalling Command Line Tools fixed the issue:
xcode-select --install
Is it safe to completely uninstall previous version of XCode and Install the XCode 4.5? because...
I just uninstalled XCode 4.2, and it mostly removed all the files in the Developer Folder, now I installed the 4.5, but it scares me since there is nothing in the Developer Folder.
Would XCode still be working even if that's the case? Thanks
Xcode 4.4+ was designed to be installed via the App Store and now stores everything in the Xcode.app bundle in your /Applications directory.
Make sure you use xcode-select to select the new path for your Xcode installation, and you install the command line tools from within Xcode 4.5.
From the Xcode 4.5 release notes:
Starting in Xcode 4.3, the Xcode.app file package contains all the Xcode developer tools. The man pages for the command-line tools Xcode uses are also placed in this package.
yes It's totally safe to completely uninstall the previous Xcode and install new Xcode4.5. I have done it and all works fine for me.
Just have to install the command line tools after installing the Xcode4.5 from it's preference just as show in below image :)
I understand that the /Developer folder no longer exists after installing XCode4.3. To me, this seems it would have bad consequences. First, CUDA installs into /Developer/GPU_Computing. Second, what happens to the GCC keychain? Eclipse relies on the GCC keychain command line tools, which I'm told disappear with Xcode 4.3.
Can someone shed light as to whether they have dealt with either of these problems?
Xcode 4.3 changed a lot.
Starting from the version 4.3 XCode became a standard Mac OS X application(it reside in the Application Folder), so you can try to move the GPU_Computing under the new root folder of XCode. However i think that an updated version of the CUDA SDK you add support for the new Xcode folder structure.
XCode and Apple are moving towards the new LLVM compiler, so GCC still supported for now, but it will disappear in next releases, so you should migrate to LLVM as soon as you can ...
You can still use GCC with eclipse installing Command line Developer Tools package .
You will have to install command-line tools package.
Run Xcode, open Wcode->Preferences..., and on "Components" tab on the "Downloads" screen select "Command line tools".
I can build and run CUDA Toolkit samples with that package installed.
The Mac QT Installer puts its shared libraries under /Library/Frameworks/QtXXX.Framework.
I'm building a QT application using a qmake-generated xcode project. I'd like to add these frameworks as private framewords inside my app bundle for easy deployment.
I've tried various options for doing this but I don't seem to be able to make it work. What I did -
change the Qt framework files in /Library/Frameworks/ using install_name_tool as described here
copy the these framework bundles manually to inside the app bundle
recompiling the bundle.
When I change the name of the original framework so it would appear that it's not there, the app crashes and says that it doesn't find the needed framework. What am I doing wrong?
Using xcode 4.3 on OSX 10.7.3
Some options to deploy a Qt application on Mac:
Qt comes with the macdeployqt tool, to bundle Qt with the built app bundle. The tool is a bit limited though and might or might not do what you want.
CMake comes with DeployQt4, which can also be used for deployment only, in case one doesn't want to use cmake for the build as well.
One can write his own script using install_name_tool as described in your link. If it doesn't work, check with otool -L if you replaced all absolute paths in the executable and bundled libraries. You will have to fix the paths for the bundled libraries, too! (recursively, so to say).
The latest released cmake version (2.8.7) doesn't support XCode 4.3 properly though: Since Xcode 4.3, files previously being installed to /Developer are now in /Applications/Xcode.app/Contents/Developer. cmake still expects them in /Developer. That is fixed in cmake master but not released yet. A workaround is to create a symlink:
ln -s /Applications/Xcode.app/Contents/Developer /Developer
Is it possible to have more than one version of Xcode installed at the same time?
If so, please post any tip, tricks, or potential issues to watch out for.
EDIT:
The reason I want to install multiple versions is to try out the new sdk beta, but if the new Xcode is buggy I want to be able to use the older version for my existing projects.
Yes, you can install multiple versions of Xcode. They will install into separate directories. I've found that the best practice is to install the version that came with your Mac first and then install downloaded versions, but it probably doesn't make a big difference. See http://developer.apple.com/documentation/Xcode/Conceptual/XcodeCoexistence/Contents/Resources/en.lproj/Details/Details.html this Apple Developer Connection page for lots of details. <- Page does not exist anymore!
Can I have multiple Xcode versions installed?
Solution:
Actually as many of the above answers says, it is possible.
Even according to the following Oracle Mobile Platform Blog, you can install more than one XCodes in the same Mac. The reason why you need to do that may vary according to you.
Scenario:
You might have installed only one version of XCode for now. Mostly the one release behind the latest XCode version which is available through App Store (mine I've Xcode 6.3.2 and I needed to keep it and also install Xcode 7 which is available through App Store).
For Ex:-
You have already installed XCode 6.x, and App Store has XCode 7
already given by App Store. For any reason you need to keep that Older
XCode 6.x(as you know it is stable for some time now) and also you
need to install and try out new XCode 7
So number one question might be, How and Where could you download the Mac OS X installable DMG file for XCode 7 (or may be if you wanna try out an older XCode version)? Ok, here is the direct link apple downloads (you might have to log into Apple Developer account before viewing this link correctly), or else following is a StackOverflow Q&A link which gives the answer to where to download DMG files for XCode IDEs.
So now let's assume that you have obtained any of the DMG file for the XCode version you require to install as secondarily?
Steps:
Follow the steps given bellow which I got from the above given first link of Oracles Mobile Platform Blog.
Close Xcode if running
Rename /Applications/Xcode.app to /Applications/Xcode_6.x.app
Enter the admin password when prompted
Double click the DMG file of your required, pre-downloaded Xcode and install it
Once installed it, before running it, change the new
/Applications/Xcode.app that was just installed to (according to my above given example) /Application/Xcode_7.app
Note*:
[Please patiently read this section until the next Note] When you have two versions of Xcode installed, your workstation has two versions of Command Line Tool (xcodebuild) installed too. The question is what your Terminal and Xcode build command will use to when you are building your iOS App. Because along with the Command Line Tool, iOS SDK which is being used to build your app also depends on.
My experience was I've had two Xcode versions. Xcode 10 (Old one with iOS12.0 - iphoneos12.0), and Xcode 10.1 (New one with iOS 12.1 - iphoneos12.1). So obviously the settings for Command Line Tool was selected to use xcodebuild tool from the Old app. I had to manually select it in Xcode preference window.
Where to set Command Line Tool in Xcode Preference Window?
Select the Locations tab and there, you can select all the installed versions of Command Line Tools (which is xcodebuild).
How to figure out which version of iOS SDK is being used to build your iOS App?
On your Terminal issue following command:
$> xcodebuild -showsdks
Above command should print out all the SDK details which your current Xcode configuration uses to build your Apps. And by seeing the results you will understand that your iOS/iphoneos SDK version depends on changing Command Line Tool (xcodebuild) setting on your Xcode.
Note**:
Above given Apple Downloads link and Oracles MPF blog post links might change and/or unavailable in the future.
So I hope that my this answer might be helpful to somebody else out there!
Cheers!
It's easy to have multiple Xcode installs.
In the installer there's a pulldown for the location... you just need to pick a new location when you're installing the beta version.
These instructions from an Apple dev tools evangelist have the full details (Apple dev username/password required):
https://devforums.apple.com/message/40847#40847
Then grab yourself a custom icon for the Beta version of XCode you're using, so you can tell them apart in the dock:
http://iphonedevelopment.blogspot.com/2009/03/multiple-developer-tool-installs.html
You may want to use the "xcode-select" command in terminal to switch between the different Xcode version in the installed folders.
It seems that Xcode really likes to be in the Applications folder and be called Xcode, especially when using xcodebuild (when building for Carthage for example) - and xcode-select doesn't always seem to cut it.
I have a client project that's still using Swift 2.2, and I'm stuck on Xcode 7 for that and using Xcode 8 for anything else.
So, in my Applications folder, I have Xcode 7 (renamed to Xcode_7) and Xcode 8 (renamed to Xcode_8). Then I rename whichever one I need to simply Xcode, and back again when done. It's a ball-ache, but seems to work.
This shell script simplifies it a bit…
xcode-version.sh
cd /Applications
if [[ $1 = "-8" ]]
then
if [ -e Xcode_8.app ]
then
mv Xcode.app Xcode_7.app
mv Xcode_8.app Xcode.app
echo "Switched to Xcode 8"
else
echo "Already using Xcode 8"
fi
elif [[ $1 = "-7" ]]
then
if [ -e Xcode_7.app ]
then
mv Xcode.app Xcode_8.app
mv Xcode_7.app Xcode.app
echo "Switched to Xcode 7"
else
echo "Already using Xcode 7"
fi
else
echo "usage: xcode-version -7/8"
fi
xcode-select --switch Xcode.app
Note that if you use the xcodebuild command line tool, then the last version of Xcode installed will become the default version. (A symbolic link is installed in /usr/bin.) To use the xcodebuild for the other versions of Xcode you'll need to use the version in the (xcode_install_directory)/usr/bin directory.
note To switch between different versions of the Xcode command-line tools, use the xcode-select tool mentioned by other commenters.
Multiple Versions Of Xcode & Simulators using gem Xcode::Install
Install and update your Xcodes automatically.
You can greatly simplify this process by using the
Xcode::Install Ruby Gem.
You should already have a working installation of the
Xcode Command Line Tools and a version of Ruby that supports building native extensions.
I'd suggest using Homebrew for installing
rbenv and use rbenv to install Ruby.
A guide for this can be found here and many other places.
But it should work with the stock Ruby supplied by newer macOS versions as well, if you install the gem either using sudo (not recommended) or using --user-install when installing the gem.
Installation
Basically:
# Install the Ruby Gem (I'm using rbenv, so no sudo or --user-install)
$ gem install xcode-install
# To list available versions:
# PS!You will get prompted for your Apple Developer / iCloud credentials)
# It's using Apple's own API's so 2FA are supported if enabled
$ xcversion list
6.0.1
6.1
6.1.1
6.2 (installed)
6.3
# To update the list of available versions, run:
$ xcversion update
# To install a certain version, simply:
$ xcversion install 8
##################################################################### 100.0%
Please authenticate for Xcode installation...
Xcode 8
Build version 6D570
This should download and install and activate that version of Xcode.
You can start it from /Applications as usual.
The new version will also be automatically selected for CLI commands
To select a different version as active, you'll run:
xcversion select <version_number>
from the list of installed versions, marked as (installed) like:
# To see the active version in use:
$ xcversion selected
# To select and activate an installed version:
$ xcversion select 8
# To select, activate and change the symlink in /Apllications
$ xcversion select 8 --symlink
Other fun stuff, Simulators etc
Xcode::Install can also install Xcode's Command Line Tools by calling
xcversion install-cli-tools
and can also manage your local simulators using the simulators command.
But instead of repeating more information that is probably going to change over time, head over to the project's GitHub page
for more about this gem.
Staring with Xcode 9, the beta Xcode is labeled 'Xcode-beta.app' and is designed to live side by side with the production version. Info can be found in the Xcode release notes here. (Not using direct link because it breaks often).
From Apple:
Xcode 9 beta 4 can coexist with previous versions of Xcode. Prerelease
versions of Xcode are made available from developer.apple.com,
packaged in a compressed XIP file. To install Xcode during the beta
period, download the XIP file, double-click the file to expand it in
place, then drag Xcode-beta.app to the Applications folder
Download a version
The beta and stable releases can be taken from the Developer Software downloads Application tab, here), but older versions can be taken from here. Just extract the .xib and put Xcode-beta.app in your Applications folder.
Switch versions
Using the beta: sudo xcode-select -s /Applications/Xcode-beta.app/Contents/Developer
Using the original: sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
Check version changed
You can validate the version has changed by running xed --version, and it will output the correct version: e.g. xed version 12.5 or xed version 13.0
To have multiple Xcode instances installed you can put them to different folders for example /Developer5.0.2/Xcode, but to use them in CI or build environment(command line) you need to setup some environment variables during the build.
You can have more instructions here.
So it is working not just with beta and fresh release, also it's working for the really old versions, you might need it to use with Marmalade or Unity plugins which is not support the latest Xcode versions yet(some times it's happens).
Whatever advice path you go down, make a copy of your project folder, and rename the external most one to reflect what XCode version it is being opened in.
Your choice on whether you want it to update syntax or not, but the main reason for all this bovver is your storyboard will be altered just by looking. It may be resolved by the time a new reader coming across this in the future, or
All the updates for new version of xcode will be available in appstore if you have installed the version from appstore. If you just paste the downloaded version appstore will show install not update. Hence keep the stable version downloaded from appstore in your applications folder.
To try new beta releases i usually put it in separate drive and unzip and install it there. This will avoid confusion while working on stable version.
To avoid confusion you can keep only the stable version in your dock and open the beta version from spotlight(Command + Space). This will place beta temporarily on dock. But it will make sure you don't accidentally edit your client project in beta version.
Most Important:- Working on same project on two different xcode might create some unwanted results. Like there was a bug in interface builder that got introduced in certain version of xcode. Which broke the constraints. It got fixed again in the next one.
Keep track of release notes to know exactly what are additional features and what are known issues.
First, remove the current Xcode installation from your machine. You can probably skip this step but I wanted to start fresh. Plus — Xcode was behaving a little weird lately so this is a good opportunity to do that.
Install Xcode 8 from the App Store. Make sure project files (.xcodeproj) and workspace files (.xcworkspace) can be opened with the new Xcode installation (remember to select the Later option whenever prompted).
Download the Xcode 7.3.1 dmg file from Apple. Double-tap the newly downloaded dmg file in order to get the standard “Drag to install Xcode in your Applications folder”. Don’t do that. Instead, drag the Xcode icon to the desktop. Change the file name to Xcode 7.3.1. Now drag it to the Applications folder.
Now you have two versions of Xcode installed on your machine. Xcode 7.3.1 and Xcode 8.
Details: Install Xcode 7 & Xcode 8 side by side
