compile php old extensions for new zend api php 5.4.9

Hello, I have ubuntu 12.04 lts+php 5.4.9. I tried to download and build the last version of the memtrack extension. Following the standard procedure configure, make,... on the compiling pass In memtrack.c, I get: warning: assignment discards 'const' qualifier from pointer target type [enabled by default] at the following lines: line 75:14: line 77:14: line 82:18: line 84:18: line 88:10: line 90:10: then, In function 'memtrack_execute_internal' in memtrack.c: warning: initialization discards 'const' qualifier from pointer target type [enabled by default] at the following lines: 341:21: 383:21: then the more serious: memtrack.c, line 112:63: error: 'znode_op' has no member named 'op_type' line 113:12: error: 'znode_op' has no member named 'u' In function 'memtrack_execute': This on line 113, I found that I can solve it, substituting the line 113 with switch (exec_data->opline->extended_value) { But I got lost for the rest and I don't manage to solve the op_type. And finally, I get also: /usr/local/include/php/Zend/zend_execute.h:380:22: note: expected 'const char ** ' but argument is of type 'char **' Your help is highly appreciated to get it out.
