I trying to install pthreads on Mac Os X. When I execute:
sudo pecl install pthreads
I get error:
checking checking for ZTS... configure: error: pthreads requires ZTS, please re-compile PHP with ZTS enabled ERROR: `/private/tmp/pear/temp/pthreads/configure' failed
So the question is how to recompile php with ZTS enabled for OS X?
I suggest you don't recompile OS X native php. Instead build and install new thread-safe version to different location.
If you use homebrew you should install it with -with-thread-safety option.
If you prefer to build it manually add --enable-maintainer-zts option to configure script.
Sadly Homebrew is not supporting the thread-safe version anymore: https://github.com/Homebrew/homebrew-core/blob/master/Formula/php.rb#L56
