Unsupported compiler 'com.apple.compilers.llvmgcc42' xcode 5 DP

Question

I have a project which contains Geos and Proj inside it. Before Xcode 5 I compiled them with LLVM GCC 4.2 compiler, but in Xcode 5 DP I get an error about unsupported compiler. Choosing another compiler get to compilation errors depends on syntax. How can I fix this trouble?

Answer 1

A) Stop using Xcode 5

or

B) Fix the errors in your code

I know you won't like that answer but Apple has stated their displeasure for GCC on many occasions and declared it a deprecated technology.

@BraveS You mean the switching the compiler one? If you read the question, OP indicates that they tried that already and got errors. – Spivey

Sorry but this answer is useless. If I had the power, I'd remove it from the internets. – Kutchins

@Kutchins You got a better one? ;) Apparently OP was ok with it since they accepted it... – Spivey

@borrrden, (+) well done! all of those who voted to the other answer didn't read the question :) (still the other answer is the one that helped me...) – Atwekk

@Atwekk Indeed, the other answer is helpful to 99% of people, however the person who asked this question is one of the other 1% haha. – Spivey

You obviously have a lot of wisdom to share. Why stifle it with cynicism? – Portion

don't delete the answer please and also the conversation too. Because it is a good lesson for us . – Vania

@Spynet I have no intention to at this point (and so far I haven't been able to since it is accepted :p). I think I even got a medal for having so a low voted accepted answer. – Spivey

I hope you have mistaken me , even n number of down votes ( you didn't delete answer ), i really appreciate you are leaders for us. and also your the so glittering stars. – Vania

Answer 2

Change your compiler for C/C++/Objective-C:

Xcode > Target > Build Settings > Build Options > Compiler for C/C++/Objective-C

Select Default compiler (Apple LLVM x.y)

99 problems but a compiler ain't one – Portion

Default compiler (Apple LLVM x.y) in that x and y will be your Xcode LLVM version – Vania

Answer 3

If you are compiling from the command line (like I do when building GEOS and proj4) The following command will find the correct compiler for you and run it.

xcrun --sdk iphoneos clang

Or use iphonesimulator instead of iphoneos if you want to build for the sim.

do you add GEOS and proj4 as compiled static library? In my project they are attached as source code – Aunt
