#: * `install` [`--debug`] [`--env=`<std>|<super>] [`--ignore-dependencies`] [`--only-dependencies`] [`--cc=`<compiler>] [`--build-from-source`|`--force-bottle`] [`--devel`|`--HEAD`] [`--keep-tmp`] <formula>:
|
|
#: Install <formula>.
|
|
#:
|
|
#: <formula> is usually the name of the formula to install, but it can be specified
|
|
#: several different ways. See [SPECIFYING FORMULAE][].
|
|
#:
|
|
#: If `--debug` is passed and brewing fails, open an interactive debugging
|
|
#: session with access to IRB or a shell inside the temporary build directory.
|
|
#:
|
|
#: If `--env=std` is passed, use the standard build environment instead of superenv.
|
|
#:
|
|
#: If `--env=super` is passed, use superenv even if the formula specifies the
|
|
#: standard build environment.
|
|
#:
|
|
#: If `--ignore-dependencies` is passed, skip installing any dependencies of
|
|
#: any kind. If they are not already present, the formula will probably fail
|
|
#: to install.
|
|
#:
|
|
#: If `--only-dependencies` is passed, install the dependencies with specified
|
|
#: options but do not install the specified formula.
|
|
#:
|
|
#: If `--cc=`<compiler> is passed, attempt to compile using <compiler>.
|
|
#: <compiler> should be the name of the compiler's executable, for instance
|
|
#: `gcc-4.2` for Apple's GCC 4.2, or `gcc-4.9` for a Homebrew-provided GCC
|
|
#: 4.9.
|
|
#:
|
|
#: If `--build-from-source` is passed, compile from source even if a bottle
|
|
#: is provided for <formula>.
|
|
#:
|
|
#: If `--force-bottle` is passed, install from a bottle if it exists
|
|
#: for the current version of OS X, even if custom options are given.
|
|
#:
|
|
#: If `--devel` is passed, and <formula> defines it, install the development version.
|
|
#:
|
|
#: If `--HEAD` is passed, and <formula> defines it, install the HEAD version,
|
|
#: aka master, trunk, unstable.
|
|
#:
|
|
#: If `--keep-tmp` is passed, the temporary files created for the test are
|
|
#: not deleted.
|
|
#:
|
|
#: To install a newer version of HEAD use
|
|
#: `brew rm <foo> && brew install --HEAD <foo>`.
|
|
#:
|
|
#: * `install` `--interactive` [`--git`] <formula>:
|
|
#: Download and patch <formula>, then open a shell. This allows the user to
|
|
#: run `./configure --help` and otherwise determine how to turn the software
|
|
#: package into a Homebrew formula.
|
|
#:
|
|
#: If `--git` is passed, Homebrew will create a Git repository, useful for
|
|
#: creating patches to the software.
