[SOLVED] Error "You need a C++ compiler..." when installing Qt SDK on Mac
-
I've been using Qt for quite a while on Windows. I just got a Mac and tried to install the Qt SDK on it, but got an error that said I need a C++ compiler, and to download XCode. So I downloaded XCode through the app store, installed it, and then tried to install the Qt SDK again, but got the same error.
I then tried to install it anyways (there's an option to continue), but then I get errors about "Can't start the process install_name_tool"...
I'm using OS X Lion with the latest updates installed.
What should I do?
-
Install command line tools in addition to Xcode. I'm not an expert on mac, myself, but it might help. They are available (as a single package) on Apple's developer page.
-
Ah, I forgot - it's also possible, that you have to set your xcode folder with xcode-select. Best option: do both :)
-
Are you able to compile other, non-Qt code?
-
I mean compile in terminal. Xcode is probably setting up the environment in the background.
-
Yeah, Terminal doesn't work. I think I misunderstood your first reply. When you said "command line tools" I thought you were talking about Terminal, since I tried searching the Mac app store for command line tools and didn't find anything. But now I realize it's just an add-on. I'll try installing it.
-
Yeah, those tools are not in App Store, they have to be downloaded separately. Okay then, maybe this time it works.

You're welcome :) Just to fulfill the bureaucracy, please add "[Solved]" to the beginning of the subject of this topic. I've already tagged it accordingly.

I'm glad that solved solved the problem!
Can you let me in on the secret of where to get these tools? I hope that I don't have to download Xcode again - that took nearly a day out here.Dumb question. See the very first reply!!!!!
-
In new Xcode releases (>= 4.3) cmd line tools can be installed through Xcode Preferences window (although getting the package from dev page is still OK and valid ;)).

Please help!
I have done all the steps here, but I still get the same error.
Does anyone can please help?!
I have been stuck on a couple of days with it ...Thanks

Best way is of course to get a real OS like Linux or even Windows, if you feel masochistic.
Sorry, couldn't stop myself, but I don't like Mac OS. Jokes aside now, and onto your question: I think we need a bit more data. What have you set xcode-select path to? Which version of Xcode are you using (and which MacOS)? Is the situation the same as for wayfaerer, that is - Xcode compilation works, but command line fails?
-
Yes, I think you are right. I might stick with Ubuntu to develop in C++.
I am still fighting with MacOS because I have a lot of friends that love Xcode, so I am still giving a try. But eventually (very soon) I might abandon MacOS for that!! :)
I am using Lion, and Xcode 4.4 with command line installed. I used the command:
sudo xcode-select -switch /Applications/Xcode.app/Contents/DeveloperAs I don't have experience with Xcode so I am not using it. I just wrote a little program using vi and complied using g++ and c++, through Terminal program.
This command line should be used inside XCode?
There is still hope for me? :0)
Thanks a lot!
-
Hm, so standard compilation works, yet you still can't install the SDK? I'm out of ideas, apart from one workaround: install Qt libraries and QtCreator separately, without using the SDK.
-
Oh, and be sure to use 4.8.2, as makespecs for xcode are not working with 4.8.1.
-
Ok Gene! Thanks! I will follow your suggestion!
