README: Fix non-existent iconv in macOS instruction
#19475
Conversation
Agree this is correct version. Looks like I copied from the linux instruction |

Thanks, will merge after confirmation that the updated docs do indeed allow for build PHP |

Okay, do you want to add that part to the documentation? |
Follows-up 22e444c (phpGH-18670). There is currently no formula called "iconv". [1][2] ``` $ brew install iconv Warning: No available formula with the name "iconv". Did you mean icon or cconv? ``` There package is called "libiconv". [3] Once installed, `./configure` still fails due to a discovery issue. ``` $ ./configure --enable-debug … checking for libiconv... no configure: error: Please specify the install prefix of iconv with --with-iconv=<DIR> ``` In 2020, as part of the switch from Intel to ARM, Homebrew adopted /opt as the standard location instead of /usr/local. [4][5] Rather than complicating the README with a mandatory `--with-iconv` path (or --without-iconv) for macOS users, improve the discovery to support Homebrew's new location. Place it after /usr/local, so that /usr/local remains the preferred place for system overrides (in case both are present). Place it before /usr, because there may be older system versions of these packages on macOS that would otherwise have precedence, making it impossible to satisfy version requirements.

@DanielEScherzer Sure! I believe that would require splitting the "configure" step by platform, like we do for the dependency installation step. Perhaps we can avoid this by fixing the discovery issue instead? I know very little about autoconf and m4, but the following change in - for i in $PHP_ICONV /usr/local /usr; do
+ for i in $PHP_ICONV /usr/local /opt/homebrew/opt/libiconv /usr; doI've amended the PR to include this. |

Unfortunately I also don't know too much about autoconf and m4, @petk would you mind reviewing? |

Little subtlety, because you can possibly have two different installations of homebrew, usually the one for rosetta is in /usr/local so in that case you would still need to set --with-iconv path explicitly with that order if you want for native arm64. |

Follows-up 22e444c (GH-18670). There is currently no formula called "iconv" at https://brew.sh/ or https://github.com/Homebrew/homebrew-core/.
There is one called
libiconv, however.https://formulae.brew.sh/formula/libiconv
