AIX + PHP Extension Module Does Not Work (giving core dump at zend_parse_parameters) View as Markdown

Hi ,
I am writing a php extension module on AIX 4.3.3 RS6000 machine.I
have compiled php as CGI.When I test my php extension module function
from a test php script I get a CORE dump.The gdb php core is as below
Core was generated by `php'.
Program terminated with signal 11, Segmentation fault.
#0 0xd0990180 in zend_parse_parameters ()
(gdb) bt

#6 0x100001dc in __start ()
I have tried all combinations of ZTS=0 ZEND_DEBUG =0
ZTS=0 ZEND_DEBUG =1
ZTS=1 ZEND_DEBUG =0
ZTS=1 ZEND_DEBUG =1
for compiling php as well as my extension module. All give the same
result :-(
Has anyone encountered this on a AIX machine.
If not atleast has anyone successfully tested a PHP extension module on
a AIX machine.I urgently need some Help.

I have followed the following steps to create the extension module:

1. ran the ext_skel command i.e. ext_skel --extname=rot13 --proto=rot13.def
2. with rot13 as current folder I ran phpize for creating a self contained extension.
3. /usr/local/php-4.3.2/ext/rot13> ./configure
4. /usr/local/php-4.3.2/ext/rot13> make
5. /usr/local/php-4.3.2/ext/rot13> make install
6. librot13.a is generated.
7. when I do a ldd ./librot13.a i get error as
   exec(): 0509-036 Cannot load program ./librot13.a. because of the following errors:
   0509-022 Cannot load module ./librot13.a.
   0509-103 The module has an invalid magic number.
8. so I used the library rot13.so.0 and got the core dump at zend_parse_parameters.
   It seems my extension is not getting the reference to zend_parse_parameters function in php.The same thing runs withou any problem on Linux as well as Windows.

Thanks & Regards
