Extensions

Hi, I've got some problems when I make my own extension. I followed this step: $PHP_SRC/ext/ext_skel my_module $PHP_SRC/buildconf $PHP_SRC/configure $PHP_SRC/make then, I've tried this first way after removing support for the appropriate lines in $PHP_SRC/ext/my_module/config.m4: $PHP_SRC/configure --enable-my_module $PHP_SRC/make $PHP_SRC/make install Everything was going fine. I was able to call my own function in php a file. Afterwards, I've tried a second way ( this is this way which is interessing me ) after removing support for the appropriate lines in $PHP_SRC/ext/my_module/config.m4: $PHP_SRC/configure --with-my_module=shared,$PHP_SRC/my_module/ $PHP_SRC/make $PHP_SRC/make install But in my php file, when I call dl("my_module"), I've got this warning message: Warning: Unable to load dynamic library 'my_module.so' - ld.so.1: /usr/local/apache/bin/httpd: fatal: relocation error: file my_module.so: symbol alloc_globals: referenced symbol not found in /usr/local/apache/htdocs/sessions/essai/essai.php on line 3 I made a ld my_module.so and I obtained following lines: Undefined first referenced symbol in file alloc_globals vmi.so _zval_copy_ctor vmi.so _emalloc vmi.so wrong_param_count vmi.so zend_get_parameters_ex vmi.so convert_to_long vmi.so Here is my source file ( a near source code from your example on Zend.com ): /*************************************************************/ #include "php.h" ZEND_FUNCTION(essai); zend_function_entry vmi_functions[]= { ZEND_FE(essai,NULL) {NULL,NULL,NULL} }; zend_module_entry vmi_module_entry= { "Vmi", vmi_functions, NULL,NULL,NULL,NULL,NULL, STANDARD_MODULE_PROPERTIES }; #if COMPILE_DL_VMI DLEXPORT zend_module_entry *get_module(void) { return(&vmi_module_entry); } #endif ZEND_FUNCTION(essai) { zval **parameter; if((ZEND_NUM_ARGS() != 1) || (zend_get_parameters_ex(1, &parameter) != SUCCESS)) { WRONG_PARAM_COUNT; } convert_to_long_ex(parameter); RETURN_LONG((*parameter)->value.lval); } /*************************************************************/ Could you help me please? Thanks
