gcc linking error due to library option location

2024. 8. 13. 17:21 in 카테고리 없음

gcc 로 compile 하는데, library option을 앞에 주면 오류가 나고, 뒤에 주면 오류가 나지 않는다?

$ gcc -lm -o test test.c nml.c nml_util.c
/tmp/cc4KiP0A.o: In function `nml_mat_col_l2norm':
nml.c:(.text+0x3165): undefined reference to `sqrt'
/tmp/cc4KiP0A.o: In function `nml_mat_l2norm':
nml.c:(.text+0x3257): undefined reference to `sqrt'
collect2: error: ld returned 1 exit status

$ gcc -o test test.c nml.c nml_util.c -lm
$

어떤 문법의 오류가 있는지, gcc v7 에서의 오류인지, 찾아볼 시간이 없어서,,, 기록만 남긴다.

linking 할 때 사용하는 것이라서, 뒤에 었이야 하나?

Windows 10: 보안 업데이트 설치시 0x80070643 오류 발생 - recovery location is null

2024. 2. 11. 13:31 in Windows

Windows update 도중에 오류가 발생하고 복구가 되지 않았다.

https://sihloh4me.tistory.com/540

그래서, 여러가지 해 보았지만, 해결되지 않았다.

그런데, 마지막에 recovery partition 관련 작업을 할 때, enable 이 되지 않는 문제가 있다.

자세히 보니,

C:\>reagentc /disable
REAGENTC.EXE: Windows RE is already disabled.

C:\>reagentc /info
Windows Recovery Environment (Windows RE) and system reset configuration
Information:

Windows RE status: Disabled
Windows RE location:
Boot Configuration Data (BCD) identifier: 00000000-0000-0000-0000-000000000000
Recovery image location:
Recovery image index: 0
Custom image location:
Custom image index: 0

REAGENTC.EXE: Operation Successful.

C:\>reagentc /enable
REAGENTC.EXE: The Windows RE image was not found.

Windows RE location 필드에 아무것도 없었다.

이 부분을 설정하기 위해서는, winre.wim 파일을 R:\Recovery\WindowsRE\ 폴더에 넣은 상태로

Reagentc.exe /SetReImage [옵션] 명령을 해야 한다.

이 과정을 설명하면,

1. 설치 ISO 에서 winre.wim 파일을 추출한다.

1.1. ISO 파일에서 install.wim 꺼내기

나의 경우에는 install.wim 이 아니고, sources\install.esd 파일로 존재함

(이유는 여러 배포반이 함께 있었기 때문인 듯 하며, 이 중에서 index 3 의 파일 (Windows 10 pro 버전)을 사용함)

D:\sources>dism /get-wiminfo /wimfile:d:install.esd

1.2. “install.wim” 파일 mount

               6 Dir(s) 1,040,429,035,520 bytes free

1.3. “winre.wim” 파일 복사 (임시폴더에)

C:\> mkdir c:\tmp
C:\> copy f:\mnt\windows\system32\recovery\winre.wim c:\tmp

1.4. “install.wim” 파일 unmount (옵션은 /discard 혹은 /commit 아무거나)

D:\sources>dism /unmount-image /mountdir:"f:\mnt" /discard

Deployment Image Servicing and Management tool
Version: 10.0.19041.1

Unmounting image
[==========================100.0%==========================]
The operation completed successfully.

D:\sources>

참고: https://sprout13.tistory.com/54

2. “winre.wim” 파일을 Recovery partition에 복사한다.

C:\> reagentc.exe /Disable /target C:\windows
C:\> md R:\Recovery\WindowsRE
C:\> attrib -h -r -s R:\*.* /s /d
C:\> attrib -h -r -s R:\Recovery\WindowsRE\*.* /s /d
C:\> copy c:\tmp\winre.wim R:\Recovery\WindowsRE\

3. “/SetReImage” 를 한다.

C:\> reagentc.exe /SetReImage /path R:\Recovery\WindowsRE /Target C:\Windows

C:\> reagentc.exe /enable
C:\> reagentc.exe /enable /target C:\windows
C:\> reagentc.exe /info /target C:\windows

이제 Windows RE location 필드가 설정되어 있다.

reboot 한 후, windows update를 하니 정상적으로 완료되었다.

그럼.

이렇게 오류가 발생하였다. 찾아 보니,,

linux-imx 컴파일 도중에 발생한 것으로, linux kernel 의 include/linux/moduleparam.h 화일에서 line 236 에 문제가 있다. 다음과 같이 [ perm, ] 으로 변경하면 문제가 해결된다.
