Ubuntu Virtual Box Start Error

Posted on July 25, 2011 by pchero

Ubuntu 11.04 Kernel Version

Linux localhost.localdomain 2.6.18-194.32.1.el5 #1 SMP Wed Jan 5 17:53:09 EST 2011 i686 i686 i386 GNU/Linux

환경에서 Virtual Box 를 구동하려고 하니 다음과 같은 에러메시지가 나타났다.

“Failed to start the virtual machine WindowsXP.
Failed to open/create the internal network ‘HostInterfaceNetworking-eth0’ (you might need to modprobe vboxnetflt to make it accessible) (VERR_SUPDRV_COMPONENT_NOT_FOUND).
Please install the virtualbox-ose-dkms package and execute ‘modprobe vboxdrv’ as root (VERR_SUPDRV_COMPONENT_NOT_FOUND).”

이유인즉, 두 개의 모듈 vboxnetflt 와 vboxdrv 이 적재 되지 않아서 발생하는 문제였다.

vboxdrv 의 경우,

$ sudo modprobe vboxdrv

의 명령어로 로딩시킬 수 있었지만, vboxnetflt 모듈의 경우에는 다음의 에러 메시지를 내며 로딩되지 않았다.

jonathan@jonathan-laptop:~$ sudo modprobe vboxnetflt
[sudo] password for jonathan:
FATAL: Error inserting vboxnetflt (/lib/modules/2.6.32-33-generic-pae/updates/dkms/vboxnetflt.ko): Invalid module format

한참을 고민하다가 해결책을 찾았는데, 너무도 간단했다.
다음의 명령어로 모듈을 업로드 할 수 있다.

$ modprobe /lib/modules/2.6.32-33-generic-pae/updates/dkms/vboxnetflt.ko

또한, 매 재부팅시 자동으로 모듈 업로드를 설정하기 위해서, /etc/modules 의 파일을 수정해야 한다.

</etc/modules>

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with “#” are ignored.

문제는 간단했다.

SYBASE – init Script and locale error

Posted on November 3, 2010 by pchero

SYBASE 에서 다음의 init 스크립트를 사용중 stop시 locale 에러가 나타나는 것을 확인했다.

에러메시지의 내용은 다음과 같다.

jonathan@jonathan-laptop:/opt/sybase/ASE-15_0/install$ sudo /etc/init.d/sybase stop
$Stopping sybase service:

The context allocation routine failed when it tried to load localization files!!
One or more following problems may caused the failure

Your sybase home directory is /opt/sybase. Check the environment variable SYBASE if it is not the one you want!
Using locale name “ko_KR.UTF-8” defined in environment variable LANG
Locale name “ko_KR.UTF-8” doesn’t exist in your /opt/sybase/locales/locales.dat file
Success.

제일 마지막 메시지에는 Success 라고 나와있지만 ps -ef|grep sybase 명령어로 확인해본 결과 대부분의 프로세스들이 그대로 돌고있는 것을 확인할 수 있었다.

무엇이 문제일까.

에러 메시지에서 해답을 찾았다. 내가 사용하는 “ko_KR.UTF-8” locale을 정의(찾을 수)없다는 메시지였다.

먼저 내가 사용하는 리눅스에서의 로케일을 변경하려고 했으나 생각되로 잘 되지 않았다. 왜냐하면 SYBASE에서 어떤 로케일들을 지원하는지 아직 몰랐기 때문이다.

SYBASE에서 지원하는 locale 하는 로케일은 다음의 파일에서 찾을 수 있다.

/opt/sybase/locales/locales.dat

방법은 두가지가 있다. SYBASE에서 지원하는 로케일에 맞추거나 위의 파일에 자신이 사용하는 로케일을 추가하거나.

필자는 로케일을 추가하는 방법을 선택하였다.

/opt/sybase/locales/locales.dat

파일을 열어 자신의 OS를 찾아 아래쪽에 양식에 맞게 추가하도록 하자.

[linux]
locale = ko_KR.UTF-8, korean, eucksc
locale = ko_KR.949, korean, cp949
locale = korean.euc, korean, eucksc

위쪽 굵게 표시한 부분이 필자가 추가한 부분이다.

이후, 아무런 에러 메시지 없이 정상적으로 종료가 되는 것을 확인할 수 있었다.

jonathan@jonathan-laptop:/opt/sybase/ASE-15_0/install$ sudo /etc/init.d/sybase stop
$Stopping sybase service: Success.

/usr/include/features.h 파일에는 컴파일 할 때 사용하는 -D 옵션과 긴밀한 관계가 있다.

어떤 Define을 하느냐에 따라 각기 다른 내용의 컴파일과 링크가 이루어 진다.

그 내용을 /usr/include/features.h 파일의 전문을 여기에 싣는다.

#ifndef _FEATURES_H
#define _FEATURES_H 1

/* These are defined by the user (or the compiler)
to specify the desired environment:

   __STRICT_ANSI__ ISO Standard C.
   _ISOC99_SOURCE Extensions to ISO C89 from ISO C99.
   _POSIX_SOURCE IEEE Std 1003.1.
   _POSIX_C_SOURCE If ==1, like _POSIX_SOURCE; if >=2 add IEEE Std 1003.2;
   if >=199309L, add IEEE Std 1003.1b-1993;
   if >=199506L, add IEEE Std 1003.1c-1995;
   if >=200112L, all of IEEE 1003.1-2004
   if >=200809L, all of IEEE 1003.1-2008
   _XOPEN_SOURCE Includes POSIX and XPG things. Set to 500 if
   Single Unix conformance is wanted, to 600 for the
   sixth revision, to 700 for the seventh revision.
   _XOPEN_SOURCE_EXTENDED XPG things and X/Open Unix extensions.
   _LARGEFILE_SOURCE Some more functions for correct standard I/O.
   _LARGEFILE64_SOURCE Additional functionality from LFS for large files.
   _FILE_OFFSET_BITS=N Select default filesystem interface.
   _BSD_SOURCE ISO C, POSIX, and 4.3BSD things.
   _SVID_SOURCE ISO C, POSIX, and SVID things.
   _ATFILE_SOURCE Additional *at interfaces.
   _GNU_SOURCE All of the above, plus GNU extensions.
   _REENTRANT Select additionally reentrant object.
   _THREAD_SAFE Same as _REENTRANT, often used by other systems.
   _FORTIFY_SOURCE If set to numeric value > 0 additional security
   measures are defined, according to level.

   The `-ansi’ switch to the GNU C compiler defines __STRICT_ANSI__.
   If none of these are defined, the default is to have _SVID_SOURCE,
   _BSD_SOURCE, and _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
   200112L. If more than one of these are defined, they accumulate.
   For example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE
   together give you ISO C, 1003.1, and 1003.2, but nothing else.

These are defined by this file and are used by the
header files to decide what to declare or define:

   __USE_ISOC99 Define ISO C99 things.
   __USE_ISOC95 Define ISO C90 AMD1 (C95) things.
   __USE_POSIX Define IEEE Std 1003.1 things.
   __USE_POSIX2 Define IEEE Std 1003.2 things.
   __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
   __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
   __USE_XOPEN Define XPG things.
   __USE_XOPEN_EXTENDED Define X/Open Unix things.
   __USE_UNIX98 Define Single Unix V2 things.
   __USE_XOPEN2K    Define XPG6 things.
   __USE_XOPEN2K8 Define XPG7 things.
   __USE_LARGEFILE Define correct standard I/O things.
   __USE_LARGEFILE64 Define LFS things with separate names.
   __USE_FILE_OFFSET64 Define 64bit interface as default.
   __USE_BSD Define 4.3BSD things.
   __USE_SVID Define SVID things.
   __USE_MISC Define things common to BSD and System V Unix.
   __USE_ATFILE Define *at interfaces and AT_* constants for them.
   __USE_GNU Define GNU extensions.
   __USE_REENTRANT Define reentrant/thread-safe *_r functions.
   __USE_FORTIFY_LEVEL Additional security measures used, according to level.
   __FAVOR_BSD Favor 4.3BSD things in cases of conflict.

   The macros `__GNU_LIBRARY__’, `__GLIBC__’, and `__GLIBC_MINOR__’ are
   defined by this file unconditionally. `__GNU_LIBRARY__’ is provided
   only for compatibility. All new code should use the other symbols
   to test for features.

   All macros listed above as possibly being defined by this file are
   explicitly undefined if they are not explicitly defined.
   Feature-test macros that are not defined by the user or compiler
   but are implied by the other feature-test macros defined (or by the
   lack of any definitions) are defined by the file. */

배포판에 설치된 GCC 버전정보

Posted on September 2, 2010 by pchero

Linux/Unix 프로그래밍을 하다보면 GCC 버전에 영향을 받는 경우가 있다.

예를 들면 ACE 라이브러리를 컴파일 할 경우, gcc-4.x 대의 버전에는 컴파일 오류가 발생한다.

그래서 부득이 gcc/g++ 을 다시 설치하려고 해도 여의치 않는 경우가 많다. 이럴 경우 다른 배포판을 찾아보게 되는데, 여기에 배포판마다 가지고 있는 gcc의 버전 정보를 싣는다.
