Module: Superenv Private

Includes:
OS::Linux::Superenv, OS::Mac::Superenv, SharedEnvExtension, Utils::Output::Mixin
Included in:
Sorbet::Private::Static::ENVClass
Defined in:
extend/ENV/super.rb

Overview

This module is part of a private API. This module may only be used in the Homebrew/brew repository. Third parties should avoid using this module if possible, as it may be removed or changed without warning.

Why superenv?

  1. Only specify the environment we need (NO LDFLAGS for cmake)
  2. Only apply compiler-specific options when we are calling that compiler
  3. Force all incpaths and libpaths into the cc instantiation (fewer bugs)
  4. Cater toolchain usage to specific Xcode versions
  5. Remove flags that we don't want or that will break builds
  6. Simpler code
  7. Simpler formulae that just work
  8. Build-system agnostic configuration of the toolchain

#deparallelize(&block) ⇒ T.untyped

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Removes the MAKEFLAGS environment variable, causing make to use a single job. This is useful for makefiles with race conditions. When passed a block, MAKEFLAGS is removed only for the duration of the block and is restored after its completion.

Parameters:

  • block (T.proc.returns(T.untyped), nil)

Returns:

  • (T.untyped)

  #
  # O - Enables argument refurbishing. Only active under the
  #     make/bsdmake wrappers currently.
  # x - Enable C++11 mode.
  # g - Enable "-stdlib=libc++" for clang.
  # h - Enable "-stdlib=libstdc++" for clang.
  # K - Don't strip -arch <arch>, -m32, or -m64
  # d - Don't strip -march=<target>. Use only in formulae that
  #     have runtime detection of CPU features.
  # D - Generate debugging information
  # w - Pass `-no_weak_imports` to the linker
  # f - Pass `-no_fixup_chains` to `ld` whenever it
  #     is invoked with `-undefined dynamic_lookup`
  # o - Pass `-oso_prefix` to `ld` whenever it is invoked
  # c - Pass `-ld_classic` to `ld` whenever it is invoked
