Similar syntax causes strange, repeated compile errors when building PHP from source on Windows

Question

I am trying to build PHP from source per these instructions. The configure works really well, but when I get to the nmake part, things fall apart. I have no idea why I am getting errors about struct's, the lines referenced are functions!

I have put the problematic zend_interfaces.c here.

Zend\zend_interfaces.c(320) : error C2332: 'struct' : missing tag name
Zend\zend_interfaces.c(320) : error C2143: syntax error : missing ')' before 'type'
Zend\zend_interfaces.c(320) : error C2055: expected formal parameter list, not a type list
Zend\zend_interfaces.c(320) : error C2143: syntax error : missing ';' before ','

Answer 1

Are you sure that zend_class_entry is defined as a variable type, maybe you aren't including a header or something?

I would expect that it would be because clearly PHP has been compiled for windows before.

Answer 2

I just deleted the first argument from the functions because they appeared to not be used.

Now everything works....

Strange....
