Установка GDB со всеми целями на Mac с помощью Homebrew

Question

Я не могу установить gdb со всеми включенными целями на Mac OSX Mojave (10.14) с помощью Homebrew (2.0.0).

Я пробовал: brew install gdb --enable-targets=all и brew install gdb --with-all-targets и получать Error: invalid option: --enable-targets=all и Error: invalid option: --with-all-targets

brew info gdb возвращает:

gdb: stable 8.2.1 (bottled), HEAD
GNU debugger
https://www.gnu.org/software/gdb/
Not installed
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/gdb.rb
==> Dependencies
Build: pkg-config ✔
==> Options
--HEAD
    Install HEAD version
==> Caveats
gdb requires special privileges to access Mach ports.
You will need to codesign the binary. For instructions, see:

  https://sourceware.org/gdb/wiki/BuildingOnDarwin

On 10.12 (Sierra) or later with SIP, you need to run this:

  echo "set startup-with-shell off" >> ~/.gdbinit
==> Analytics
install: 13,521 (30 days), 42,502 (90 days), 153,991 (365 days)
install_on_request: 12,161 (30 days), 37,200 (90 days), 132,057 (365 days)
build_error: 0 (30 days)

Обратите внимание, что ни один из параметров не указан в info, отображаемом в ссылке gdb.rb.Что мне здесь не хватает?

Другие опции, например --disable-debug, тоже не работают.Если я удаляю все опции, установка работает нормально.

Answer 1

Просто разобрался.Я создал измененную версию файла формулы .rb в своем /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/gdbCustom.rb и добавил недостающие параметры сборки.Я основал его на этой формуле: https://raw.githubusercontent.com/Homebrew/homebrew-core/9ec9fb27a33698fc7636afce5c1c16787e9ce3f3/Formula/gdb.rb

Да, я новичок в Homebrew, но теперь я лучше понимаю, как работают формулы.В случае, если это помогает другим, смотрите ниже final .rb.После добавления файла в указанный выше каталог homebrew-core/Formula запустите brew install gdbCustom --with-all-targets.make занимает несколько минут, так что наберитесь терпения.
