gcc의 Warning 옵션 http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
우분투 8.04에서 Eclipse 사용 시 다음과 같은 메시지가 뜬다면!
Could not initialize the application’s security component. The most
likely cause is problems with files in your application’s profile
directory. Please check that this directory has no read/write
restrictions and your hard disk is not full or close to full. It is
recommended that you exit the application and fix the problem. If you
continue to use this session, you might see incorrect application
behaviour when accessing security features.
$HOME/.mozilla/eclipse 폴더를 수동으로 만들어 주시면 됩니다.
