macOS 10.15 (Catalina) Build Errors

[vicchi]

I'm trying to build php-postal on my development MacBook Pro ...

macOS version: 10.15.1

CC version:

$ cc --version
Apple clang version 11.0.0 (clang-1100.0.33.12)
Target: x86_64-apple-darwin19.0.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

PHP version:

$ php --version
PHP 7.4.0 (cli) (built: Nov 29 2019 16:18:44) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies

... libpostal is previously built and installed into /opt/custom (so not to pollute Homebrew's install in /usr/local) and following along with the build steps in the README:

make: *** [php_postal.lo] Error 1

Adding a very quick and dirty hack of adding typedef unsigned long ulong; into php_postal.h allows the build and test to run successfully.

However ... running sudo make install then fails with ...

$ sudo make install
Password:
mkdir: /usr/local/Cellar/php/7.4.0/pecl: File exists
mkdir: /usr/local/Cellar/php/7.4.0/pecl: No such file or directory
make: *** [install-modules] Error 1

Has anyone come across these issues or better yet, are in the process of fixing them?

Resolved part 1:

mkdir: /usr/local/Cellar/php/7.4.0/pecl: File exists
mkdir: /usr/local/Cellar/php/7.4.0/pecl: No such file or directory
make: *** [install-modules] Error 1

This seems to be linked to the changeover for Homebrew from supporting PHP extensions to requiring installation via pecl. If /usr/local/Cellar/php/[version]/pecl exists and if a symlink, removing this and running sudo make install installs successfully.

Resolved part 2: please see PR #23

[cmb69]

Regarding part 2: this is due to the fallback definition of ulong having been removed in PHP 7.4. Would be fixed with PR #25 as well (there, I just replaced ulong with unsigned long).
