dependencies - Homebrew: `brew uses --installed gcc` does not give any result -
i want list of installed packages depend on gcc (installed homebrew). when try:
brew uses --installed gcc
it gives no result. , if check e.g. r's dependencies brew deps r
, returns gcc
(among others). assume brew uses
should @ to the lowest degree homecoming value r
.
did encounter similar problem , shed lite on this?
this not authoritative answer, appears me because r
depends on :fortran
, kind of virtual dependency can resolved in different ways. brew deps
answers question, need install before installing formula. , in case decides installing gcc
way satisfy :fortran
requirement. reverse apparently not supported: doesn't know looking @ gcc
can used resolve virtual dependency :fortran
. plausible if 1 considers way virtual dependencies implemented in homebrew. usually, looks around in file scheme see if required binary available (including ones supplied outside of homebrew), doesn't found formula dependency link 1 time finds candidate.
(in fact, case might more complex. if @ brew deps r --tree
, see dependency on :gcc
, level of virtual dependency.)
although not straight related question, note deps
default recursive uses
not. in order symmetric picture, you'd need utilize deps -1
or uses --recursive
.
gcc dependencies homebrew uses
