I believe the culprit is --enable-option-checking=fatal as it works fine without. But IMO it's just a symptom of the problem that PHPBrew adds (not sure where) --enable-json – presumably because of the variant +json. If you try -json it will add --disable-json which will result in the same error.

I came across this page which suggest that the json variant is obsolete from PHP 8.0 onwards. So I would suggest:

• To add a notice to the user when using the +json or -json explicitly for a PHP8+ installation
• Ignore the variant when using +default for a PHP8+ installation (i.e. no notice)
• Do not append the flags for PHP8+

It seems that the --enable-json option will not be found in the ./configure script when compiling the PHP 8.x versions.

The probable reason is: the PHP 8.x version always includes the json extension and the above option is removed.

Using the following steps to verify and reproduce the issue in the Ubuntu 20.04:

Any solution to this?

[theofidry]

The workaround is to not use --enable-option-checking=fatal
