Hi,

I guess I should introduce myself first: I'm Manfred Stienstra, I'm a
parttime web application programmer and parttime student Artificial
Intelligence.

I was asked by a teacher to create a php api for MonetDB [1], I started
working on that today, and I can't find out how to create a dynamic
loadable extension. The code I'm using is the standard code from
ext_skel.

I've tried this:

gcc -fpic -DCOMPILE_DL=1 -I/usr/local/include -I. -I.. -I ../..
-I../../Zend -I../../include -I../../main -I../../TSRM -c -o monet.o
monet.c
ld --export-dynamic -shared -L/usr/lib -o monet.so monet.o

but php gives this error:

Warning: dl(): Invalid library (maybe not a PHP library) 'monet.so' in
/var/www/tail.dwerg.net/htdocs/monet/index.php on line 3

Is there some way to use the php build structure to create dynamic
loadable extensions or does someone know how to fix this?

I had this problem myself recently before I figured out how to build the
standalone shared module. If memory serves me correctly your above line
is incorrect and should be as follows:

> gcc -fpic -DCOMPILE_DL_MONET=1 -I/usr/local/include -I. -I.. -I ../..
> -I../../Zend -I../../include -I../../main -I../../TSRM -c -o monet.o
> monet.c

The change was to add _MONET to the -DCOMPILE_DL portion of the
statement.

HTH,
Rob.

Hi,

As some might remember from last week, I'm trying to develop a php
extension, but I'm having a little trouble getting it compiled...

/home/dwerg/code/2003/monetdb/php-4.3.3/ext/monet/monet.c:42: error:
`zif_monet_connect' undeclared here (not in a function)
/home/dwerg/code/2003/monetdb/php-4.3.3/ext/monet/monet.c:42: error:
initializer element is not constant

Does anyone know how I can fix this?

Manfred

p.s. I didn't attach the code, because I don't want to spam the list
with big files.

Then, please place the files somewhere on the web, so we can see the code

I see something bad in php_monet.h :

PHP_FUNCTION(mysql_connect);
PHP_FUNCTION(mysql_close);

As you probably see this you misspelled the names.

Oops, sorry to have bothered you with this...
