make: /bin/sh: Operation not permitted
I am getting the following error when building in a Alpine 3.14 environment (php7.x):
creating libtool
appending configuration tag "CXX" to libtool
configure: patching config.h.in
configure: creating ./config.status
config.status: creating config.h

You can reproduce the error using this Dockerfile (Alpine 3.13 works, though):

Cannot get override_function to work on PHP7
I compiled the extension just fine on PHP7:
php -v
PHP 7.0.10-1~dotdeb+8.1 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
with Better Function Replacer (BFR) v0.1, Copyright (C) 2015, by Lukas Rist
I'm using this code to test:
<?php
$ren=rename_function('strlen', 'old_strlen');
$ovr=override_function('strlen', '$string', 'return override_lenstr($string);');
function override_strlen($string) {
return 'THIS TEXT IS ADDED '.old_strlen($string);
}
echo "Results of rename and replace: |{$ren}|{$ovr}|\n";
$var='some string to be measured';
echo "The length of '{$var}' is (override) ".strlen($var)."\n";
echo "The length of '{$var}' is (rename) ".old_strlen($var)."\n";
This is the result:
Results of rename and replace: |1||
The length of 'some string to be measured' is (override) 26
The length of 'some string to be measured' is (rename) 26
As a side note, if I remove line 3 of above (the override_function line) strlen is still available.
Also, override_function never returns true.
Regards.
