[Homebrew] ilmbase deprecated

brew upgrade ilmbase

Warning: ilmbase has been deprecated because it is not supported upstream!

neofetch를 설치하면서 ilmbase가 더 이상 사용되지 않는다는 것을 알게 되었습니다.

brew upgrade openexr with imath

homebrew를 update하니 openexr이 업데이트 목록에 해당되는 것을 알았습니다.

==> Installing dependencies for openexr: imath
==> Installing openexr dependency: imath
==> Pouring imath--3.0.1.catalina.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local

is a symlink belonging to ilmbase. You can unlink it:
  brew unlink ilmbase

To force the link and overwrite all conflicting files:
  brew link --overwrite imath

To list all files that would be deleted:
  brew link --overwrite --dry-run imath

Possible conflicting files are:
/usr/local/lib/libImath.dylib -> /usr/local/Cellar/ilmbase/2.5.5/lib/libImath.dylib

openexr, imath 모두 업데이트는 완료하였으나 이제는 사용하지 않은 ilmbase와 중복이 되어 충돌이 일어납니다.

brew doctor

Warning: Some installed formulae are deprecated or disabled.
You should find replacements for the following formulae:
  ilmbase

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause formulae that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  imath
  openexr

brew doctor를 실행한 결과 ilmbase는 역시나 더 이상 사용되지 않고, math, openexr은 unlink가 되어있어 link를 시키라고 합니다.

ilmbase, openexr의 github 설치 코드

brew info ilmbase openexr을 통하여 홈페이지를 살펴보니 각 프로그램들이 모두 동일한 홈페이지를 사용한다는 것을 알았습니다.

limbase github site

https://github.com/Homebrew/homebrewcore/blob/HEAD/Formula/ilmbase.rb

openexr github site

https://github.com/Homebrew/homebrewcore/blob/HEAD/Formula/openexr.rb

keg_only "ilmbase conflicts with openexr and imath"

ilmbase github code

두 프로그램의 설치 github 코드룰 살펴보자면 openexr github에선 아무 이상이 없었으나, ilmbase github에서 역시나 ilmbase는 openexr과 imath와 충돌이 일어난다고 언급하였습니다.

brew link, unlink 실행

두 가지 안 중에 서두에 언급하였던 ilmbase는 deprecated 가 되었다는 것을 인지하고 brew unlink ilmbase, brew link --overwrite openexr, brew link --overwrite imath를 실행하였습니다.

brew unlink ilmbase 그리고 brew doctor 을 실행

brew link --overwrite openexr && brew link --overwrite imath 실행

Ilmbase를 unlink 그리고 openexr과 imath를 link --overwrite를 하니 위 사진처럼 ilmbase 경고만 남고 나머지는 다 사라지게 되었습니다.
