Using GCC 4.2 in Xcode 4.2 iOS SDK 5.0 - iphone

I found this post about using GCC 4.2 in Xcode 4.2 StackOverflow Post.
Did anyone else receive the error "Error writing -: Broken pipe" after following the steps in the above post?
After following the steps I can see GCC 4.2 as an option for the compiler.
Compiling a project using LLVM compiler 3.0 still works, but using LLVM GCC 4.2 or GCC 4.2 generates the pipe error.
I hope someone encountered the same problem and managed to fix it!


Simple and userful solution https://github.com/kennethreitz/osx-gcc-installer/
It automates the lists of the declaration on the stackoverflow

unknown argument: '-stdc++' [-Wunused-command-line-argument-hard-error-in-future] during build in XCODE 5.1

I get this error when I build a project in XCODE 5.1. I followed Link and downloaded New command line tools from Apple.But facing same issue. Please guide me. thanks

Have 3 steps u should do to fix it:
- Remove -stdc++ in Other Linker Flags
- Add -lstdc++ into Other Linker Flags
- Add libstdc++6.09.dylib into Link binary with Libraries.
Good luck.

Follow this as it's happening because of Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn) :

Unsupported compiler 'GCC 4.2' selected for architecture 'armv7' in xcode 4.6

I accidentally updated my iphone to 6.1 and when that happened I came to know that I have to update the xcode version too to Version 4.6 (4H127), which I did. I had a requirement to read qrcode for which I was using Zxing and it was working perfectly well. After all updates, its throwing an error with build failed. The error says
"Unsupported compiler 'GCC 4.2' selected for architecture 'armv7'"
I tried searching for the answer changed the compiler from Default to LLVM GCC 4.2 from default that is APPLE LLVM Compiler 4.2 but with no change.
Please guide me to resolve the issue.

Xcode 4.4 - Inline Assembly Issue

In Xcode 4.4 I am getting error when I try to build iOS project that has methods written in assembly. I am getting error "Inline Assembly Issue - invalid operand for instruction" for this line vqrdmulh.s16 q2, q13.
I tried to compile with LLVM 4.0 and LLVM GCC 4.2 but I am getting the same error.
Project was compiling fine in previous version of Xcode.
Does someone know how to solve this error? Thanks.

Xcode 3.2.2 and LLVM version 1.0.2 failing

I have Xcode 3.2.2 and I am trying to use LLVM version 1.0.2 as a compiler.
When I do that, I see the error
Library not found for -lgcc
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang
failed with exit code 1
How do I solve that?
thanks.

You can't use LLVM to compile iPhone apps in 3.2. You'll need to use GCC.

In fact it seems that you can use LLVM on Xcode 3.2.3. I've just downloaded it now and LLVM works!!!!

UIKit SDK 3.0 error

I am using iphone_sdk_3.0_beta_5__9m2735 SDK.
When I try to compile my code using simulator 3.0 option I get following error. The code compiles for rest all simulator option ie 2.0, 2.1, 2.2, 2.2.1
While compiling my code I get following error
from /Users/videomac/manish/EXPLab/2009-05-27-11-20 myApp_LL_2/myApp_Prefix.pch:7:
In file included from /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIKit.h:30,

The errors are located in file UILocalizedIndexedCollation.h which is SDK file.I am using UIKit Framework of SDK 3.0. Can anyone tell me what should I do to remove this error?

I've traced this problem to be the compiler version being used. From what I can tell, [REDACTED] requires GCC 4.2 while iPhone SDK 2.x only works with GCC 4.0.
Here's a way to fix this.
In your Target Info, select Build separator and look for the section Compiler Version. Then:
Select the C/C++ Compiler Version row
Set the default to GCC 4.0
At the bottom-left control, hit Add Build Setting Condition
On the left, choose Device - iPhone OS 3.0
On the right, chose GCC 4.2
Repeat steps 3 to 5, now with Simulator - iPhone OS 3.0 on step 4.

Apple’s engineer had confirmed that they had a bug in UIKit framework:
We do have a simple workaround for this UIKit bug. In UILocalizedIndexedCollation.h change this:
UIKIT_EXTERN #interface UILocalizedIndexedCollation : NSObject
to
UIKIT_EXTERN_CLASS #interface UILocalizedIndexedCollation : NSObject

Firstly you should discuss beta products here.
However, this is not connected with the beta. You have an error in one of your own header filesprobably a missing '#end' statment.
BTW, google could have solved this for you rather than asking here.
