To call a C/C++ function in PHP using SWIG.

[piyushtiwari]

I have to call a C++ function in php. I tried it using swig. I wrote the interface file example.i to call the functions from example.cxx in php. To build a PHP extension, I run swig using the -php option as follows:

~$ swig -php example.i

This produced 3 files example_wrap.c, php_example.h and example.php.
Now to build the extension as a dynamically loaded module I used

cc -I.. $(PHPINC) -fpic -c example_wrap.c

It is showing errors like
example_wrap.c: 689:18: zend.h: No such file or directory
example_wrap.c: 690:22: zend_API.h: No such file or directory
example_wrap.c: 691:17: php.h: No such file or directory

For compiling I have used........

cc -I /usr/local/include/php/ -fpic -c example_wrap.c

Please suggest me what to do to make it work???

Heya, piyushtiwari. Welcome to TSDN!

You posted this in the PHP Articles section (despite the HUMONGOUS SIGN that said, "DO NOT POST QUESTIONS HERE!").

I'll go ahead and move it to the PHP FORUM so that you might actually get some responses :)

I have not used swig, therefore this is only a guess.
Perhaps you need to have the PHP source installed on your machine in order to compile extensions for it.
