Using C++11 with Eclipse in Mac Yosemite

I am using Eclipse Luna SR1a (4.4.1) and assuming you can install and run Eclipse

C++11

Download gcc-5.0-bin.tar.gz from http://hpc.sourceforge.net

Unzip the file

You will get a usr folder and the folder structure will be following

usr ▸ local ▸ bin
usr ▸ local ▸ include
usr ▸ local ▸ lib
usr ▸ local ▸ libexec
usr ▸ local ▸ share

Rename the local folder to hpc-gcc and move it to your home directory.

For my case the path will be like,

Users ▸ shahabuddin ▸ hpc-gcc ▸ bin
Users ▸ shahabuddin ▸ hpc-gcc ▸ include
Users ▸ shahabuddin ▸ hpc-gcc ▸ lib
Users ▸ shahabuddin ▸ hpc-gcc ▸ libexec
Users ▸ shahabuddin ▸ hpc-gcc ▸ share

Version Test

Create a CPP project in Eclipse and run the code

// version-test.cpp by Bill Weinman <http://bw.org/>

#include <iostream>
#include <sstream>
#include <vector>
using namespace std;

int main( int argc, char ** argv ) {
	stringstream version;
	version << "GCC version: "
			<< __GNUC__ << "." << __GNUC_MINOR__ << "." << __GNUC_PATCHLEVEL__
			<< "\nVersion string: " << __VERSION__;

	cout << version.str() << endl;

//	vector<string> v = { "one", "two", "three" }; // C++11 feature - initializer list
//
//	for( string s : v ) {	// C++11 feature - range-based for loop
//		cout << s << endl;
//	}

	return 0;
}

Output should be like,

GCC version: 4.2.1
Version string: 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56)

Configuration of C++11

Right click the project and select Properties (Cmd + I)

Under C/C++ Build -> Environment
Add these variables

Variable: CPATH
Value: ${HOME}/hpc-gcc/include

Variable: DYLD_LIBRARY_PATH
Value: ${HOME}/hpc-gcc/lib

Variable: LIBRARY_PATH
Value: ${HOME}/hpc-gcc/lib

Variable: PATH
Value: ${HOME}/hpc-gcc/bin:/usr/bin:/bin:/usr/sbin:/sbin

Finally it will look like this,

Carefully set the Variable and Value. Otherwise you might get the following error,

dyld: Library not loaded: /usr/local/lib/libmpc.3.dylib
Referenced from: /Users/shahabuddin/hpc-gcc/bin/../libexec/gcc/x86_64-apple-darwin14.0.0/5.0.0/cc1plus
Reason: image not found
g++: internal compiler error: Trace/BPT trap: 5 (program cc1plus)
make: *** [version-test.o] Abort trap: 6

Now go to C/C++ Build -> Settings

Under GCC C++ Compiler -> Miscellaneous -> Other flags
Add -std=c++11

Under GCC C Compiler -> Miscellaneous -> Other flags
Add -std=gnu11

Finally it will look like this,

Clean the project and Run again

Output should be,

GCC version: 5.0.0
Version string: 5.0.0 20141005 (experimental)

You might as well uncomment the bottom part now.

Output should be,

GCC version: 5.0.0
Version string: 5.0.0 20141005 (experimental)
