php 5.5.38在cpp中被发现

Question

我发现了一个很好的啧啧：http://www.hackingwithphp.com/20/3/0/first-step

sudo -s ENTER
./ext_skel --extame=hello

我修改了文件：

PHP_ARG_ENABLE(hello, whether to enable hello support,
   dnl Make sure that the comment is aligned:
   [  --enable-hello           Enable hello support])


./buildconf --force ENTER

./configure --enable-debug --enable-maintainer-zts --with-apxs2 --disable-cgi --enable-cli --without-pear --disable-xml --without-mysql --enable-hello    ENTER

make ENTER
make install ENTER

我的电脑：

root@DELL:~/Downloads/php-5.5.38# php -f ext/hello/hello.php
Functions available in the test extension:
confirm_hello_compiled

Speicherzugriffsfehler (Speicherabzug geschrieben)
root@DELL:~/Downloads/php-5.5.38# 

根据教程，它应该如下所示：

debian php-5.0.1$ php -f ext/hello/hello.php
Functions available in the test extension:<br>
confirm_hello_compiled<br>
<br>
Congratulations! You have successfully modified ext/hello/config.m4.
Module hello is now compiled into PHP.
