Hello everyone
for learning to develope an own external php-extension i studied the
following session under
http://devzone.zend.com/article/1021-Extension-Writing-Part-I-Introduction-to-PHP-and-Zend
and tried to develope my first extension as the examples from this site.
i use Linux (openSuse 10.2) and have compiled php 5.2.3 and apache 2.2.4
successfully.
after editing the first example of this site above (hello-world) i can
run "phpize" and "./configure --enable-hello" successfully too.
but when i run "make", i get an error message called:
susi-note:/php-5.2.3/ext/hello # make
make: *** No rule to make target `/php-5.2.3/ext/hello/hello.c', needed
by `hello.lo'. Stop.
i just covered all lines of that example in this site described above
and changed nothing from that. i guess its usually so simple that the
authors just think, it should be to compile on every system.
so i wonder about my error result.
has anybody an idea, what i can do to compile this example?
my example is the following:
under my php-source-directory i created a subfolder under the "/ext/"
directory called "hello".
in this directory i created the following files under my footer. than i
started to typing "phpsize", "./configure..." and "make" from that
directory as described in the site called above.
thank you very much for any help!
kind regards,
h. huebel

That's a bit out of the scope of this list, but a simple fix
anyway. Change config.m4:
PHP_NEW_EXTENSION(hello, hello.c, $ext_shared)
.... to....
PHP_NEW_EXTENSION(hello, php_hello.c, $ext_shared)
