Make Cross-Compiler(2); How to Build and Install GCC on Macbook Pro 2015 early

- My Development Environment
Mac OS X 10.11.1 El Capitan
already installed Binutils
already installed Xcode

It is similar to build and install Binutils but your time can waste too much.
Please do this when you have enough time.

- Procedure

1. Download GCC Source codes at https://gcc.gnu.org/ (click 'our mirror sites' after clicking any versions)

2. extract your files
example) $ cd ~/Downloads/
$ tar -zxvf gcc-5.2.tar.gz (tar.gz files can extract as zxvf command.)
$ cd gcc-5.2 (move to ~/Downloads/gcc-5.2/)
3. downloads libraries when your computer need as this command.
$ ./contrib/download_prerequisites

4. setup your platform and location.
$ export TARGET=x86_64-pc-linux
$ export PREFIX=/opt/cross (<- this location is same to setup binutils)

Confirm .bash_profile (It is already have after doing Make Cross-Compiler(1))
You can see
export PATH=/opt/cross/bin:$PATH
when you type $cat ~/.bash_profile

5. build and install

$ ./configure --target=$TARGET --prefix=$PREFIX --enable-64-bit-bfd --disable-shared --disable-nls
$ make configure-host
$ make LDFLAGS="-all-static"
$ sudo make install

6. How to test gcc cross-compiler after install that.
$ /opt/cross/bin/x86_64-pc-linux-gcc -dumpspecs | grep -A1 multilib_options

result

I use too much time. cheer up! . It is really hard to me. So I leave this text.

-My Problems
C compiler cannot create executables when I type $./configure ~~~blar~~~
Solve this problem to delete installed binutils then to reinstall them in my case.
$rm -rf /opt can removes all the binutils. ***Use caution when you type rm command.

How to setup GCC (GNU Complier Collections) on Mac OS X and test to use Vim.

If you contact GCC firstly as this page, please don't believe everything. quest yourself about this page.

My development environment
: Mac OS X 10.11.1 El Capitan on Macbook pro 2015 early
Xcode 6.3.1

* I am studying the book; 64비트 멀티코어 OS 원리와 구조. GCC installation is first procedure for it.
It is similar to '2.1 GCC 설치' page 50 to '2.2 크로스 컴파일러 만들기' page 69. but It is for Windows. So I need to do on Mac OS X.

1. Open Terminal
(Ctrl+ Space) terminal.app

2. type $xcode-select --install (* "$" means on terminal)
*If you don't know you have GCC or not, type this sentence $ gcc --version

3. click Install(설치)

4. type, too. $gcc -v

completed installation GCC.

until now, how to test GCC on Vim
Vim (old version Vi) is already installed on Mac OS X.
open your terminal.

$vi File_Name example) $vi test.c

1. Can input codes after pushing a or i or u button.

#include <stdio.h>

int main( int argc, char** argv)
{
printf("Hello World\n");
return 0;
}

2. push ESC.

3. when your cursor located bottom, type :w (it means save)

[Common Test]

4. $gcc -o test.out (It makes test.out file and It is for test)

5. $ ./test.out

You can see Hello world

[My case Test]
4. $gcc -m32 -o test32 test.c
$gcc -m64 -o test64 test.c

5. $./test32
$./test64

If you see Hello World, Your GCC can apply 64bit and 32bit.

'ls' command to see files on this location.
