I got a dynamic linker error with the __clock_gettime symbol so I did what this post said Missing symbol when installing ruby-2.3.0 on OS X 10.11.6 by RVM (i.e. xcode-select --install) and now I am getting loader errors that say that libraries were built for a newer OS version than the one I am currently running on, I dont want to upgrade my OS to the newer (Sierra) version though, is there a way you can downgrade the command line tools to an older version (10.11?)
It's unclear which version of Xcode you are using, although it is possible to have multiple versions of the command-line tools installed, which can be selected in Xcode Preferences.
Command Line tools come with Xcode. If you delete and downgrade Xcode it should do the trick. Once you delete Xcode from you applications, use "Previous versions of Xcode can also be downloaded here" link in https://developer.apple.com/support/xcode/.
SPOILER ALERT: You need to have/create an apple dev account for this
Can download command line tools without the complete Xcode application here: https://developer.apple.com/download/all/?q=command%20line%20tools

I am new to using Macports to download software I have just upgraded to Mojave and have made sure I have the latest versions of both Macports and Xcode command line tools. I have been getting the message
Warning: xcodebuild exists but failed to execute
when trying to download gnuradio. I then used 'port diagnose' and received the following message:
Error: currently installed version of Xcode, none, is not supported by MacPorts. For your currently installed system, only the following versions of Xcode are supported: 10.0
This is despite the fact that I am using xcode 10.0 and have never run anything earlier than that. Am I missing something or could it be that Mojave hasn't been available for long enough for possible bugs to be solved with the programs. If anybody has an alternate way of running gnuradio-companion i'd be happy to hear. I have already tried via home-brew but ran into problems with that as well.
Thanks for your help,
Arthur
#Wallace Huang's answer worked for me (Mojave 10.14.6):
Open Xcode
Select Preferences -> Locations
Command Line Tools version gives a drop down menu and I was able to select the single option for which version of Command Line tools I have.
Screen shot of Xcode Preferences
In Xcode 10, go to Preferences, select Locations tab, and choose a version in Command Line Tools. On a fresh install, this field is blank (hence your version is "none").
I am a Windows/Linux developer who occasionally builds for OS X - particularly in Qt.
I have a simple Qt project that I have been developing on Windows. I now wish to build it on OS X.
I am running Yosemite. I have installed Xcode 7 and am attempting to install Qt 5.5.
When I run the Qt installer, immediately after the prompt to log in to Qt (which is successful), I receive the following error:
You need to install Xcode version 5.0.0.
I have attempted to locate Xcode 5.0.0 on the Apple Developer site, but this is 2 major versions behind the most recent version, and I cannot even find an installer for it.
More to the point, I do wonder why the most recent version of Qt requires a version of Xcode that is considered so old by Apple that it's not even available.
How do I overcome this problem so that I can get Qt installed on OS X?
I ran into the same problem and solved it by following the instructions here. This link describes a similar, but slightly different installer issue.
To summarize, you need to ensure that the Xcode command line tools are installed and set up correctly. I already had them installed, but had to go into Preferences -> Locations in Xcode and set the dropdown to the currently installed version.
The link shows an earlier version of Xcode where the path is actually Preferences -> Downloads -> Components.
Once I'd made this change, the installer continued successfully.
The solution that worked for me (on OSX Sierra XCode 8.2.1) is to open XCode Preferences -> Locations.
There is a drop-down menu named Command Line Tools. Select the available XCode version here. Then restart the Qt Creator installation.
taken from the link above, this resolved my issue:
sudo /usr/bin/xcode-select -switch /Applications/Xcode.app/Contents/Developer
For me closing the prompt and smashing keys (alt F4, I know that its not windows) before the next prompt opened worked... qt is running fine now, as it doesn't need the old version.
you can find the old version of XCode on the the Apple offical site here and download .dmg of xcode 5 or 6.1 for example :
I do this and it's ok for me.
I have tried and tried (looked at many headings for this) and I still don't have an answer to my problem. I am trying to install the Pebble SDK 1.12 and install command line tools of Xcode 5.
Everytime I try xcode-select --install in terminal I get "Can't install software because it is not currently available in the Software Update server"
I have tried to reinstall Xcode and that didn't work.
When I got to Xcode-preferences-downloads there isn't a section for the command line tools.
I have also tried installing them from the Developer site but to no avail. The download looks correct and then I go to Xcode to see the preferences and the command line tools aren't listed.
Anything you all can suggest?
Using xcode-select --install in Terminal and choose install tools
On OS X 10.9, the Command Line Tools component no longer appears in the Preferences pane for Xcode 5, unlike on OS X 10.8. Also, the not currently available message appears to be a bug in OS X 10.9 when the currently installed Command Line Tools are already up-to-date. If you have a populated /usr/include directory and /usr/bin/cc --version gives you something, you're probably fine.
I was actually trying to update ruby on my OSX 10.7.5 with RVM, and after typing in the following command:
rvm install ruby
I got the following response:
Searching for binary rubies, this might take some time.
Checking requirements for osx.
Installing requirements for osx.
Updating system.......
Error running 'requirements_osx_brew_update_system ruby-2.0.0-p247',
please read /Users/username/.rvm/log/1381215459_ruby-2.0.0-p247/update_system.log
Requirements installation failed with status: 1.
Then, when I checked out the update_system.log, it showed me the actual code of a function called requirements_osx_brew_update_system(), which contained the following error message:
Xcode version older than 4.6.2 installed, download and install newer version from:
http://connect.apple.com
After installation open Xcode, go to Downloads and install Command Line Tools.
Then I proceeded to find an update for Xcode, but only found the latest Xcode 5.0, which is apparently incompatible with my OSX 10.7. Although ultimately my goal is to update ruby and install rails, which I'm sure there are many other ways to do, I'd still like to find out if I could possibly install Xcode 4.6.2 on my OSX 10.7.
UPDATE: Sorry folks, apparently my version of XCode is v4.6.1 so updating the command line tools will not work in all cases (I know for a fact it doesn't work if you're on XCode v4.3.3). YMMV
I ran into the same issue trying to do an rvm install. I got an error telling me that I needed XCode 4.6.2 or later.
Turns out all it needed was the latest version of the XCode command line tools. I followed the instructions for upgrading my command line tools from this macports article:
open the Xcode application
go to the Preferences window
open the Downloads section
click the Install button next to "Command Line Tools"
After doing this I was able to run my rvm install command and it didn't complain about upgrading XCode anymore (and finished successfully).
It seems you're going to have to install under Xcode 5. So go to https://developer.apple.com/downloads/ and log in with your developer ID to get to the older versions. There should be a 4.6.3 that you could potentially download, or even 4.6.2.
Or you could upgrade your OSX to 10.8.
Whichever you prefer.
I can't give you a direct link to it, since you need your developer information to log in yourself. But all the downloads you need are in the link provided above once you log in.
Open xcode and update it via the app store.
Then
xcode-select --install
This will install xcode via the command line
When I try and install MacPorts it complains
'Xcode is not installed, or was installed with UNIX Development (10.5+) or Command Line Support (10.4) deselected.'
I do have Xcode installed from the Appstore so I guess I just have to install these extra parts but how ?
Ive read a couple of questions on Stack Overflow about this but I think the answers must be outdated as they do notmake sense for me, I do not have an Xcode dmg I can reinstall from, and I can't see anything useful in /Developer either, or any preferences within Xcode itself.
I only want Xcode for the purposes of using Macports so I'm not familiar with it.
You probably got Xcode 4.1 from the Mac App Store. In that case, you haven't got Xcode 4.1 installed. However, you now have an Xcode installer in your Applications directory.
Spotlight should find it in any case.
The command line tools aren't included in the default install of Xcode anymore.
Goto the Xcode Preferences --> Downloads Pane --> click the Install button beside "Command Line Tools".
If you don't have Xcode installed you can get the command line tools separately as explained here..
http://osxdaily.com/2012/07/06/install-gcc-without-xcode-in-mac-os-x/
The App Store installs the XCode installer, not Xcode itself. The installer is in your applications folder. Run that.
Today, 16 Feb 2012, when I installed Xcode 4 from the App Store, there was no Setup. Just the app installed, because it was Xcode 4.3 !
Make sure that you install Xcode 4.2 with UNIX Devel. to MacPorts works!
To get the Xcode 4.2 go to https://developer.apple.com.
