Please remove Zend/zend_ini_parser.c and rerun buildconf, configure and nmake. That should help.

Thanks.

I tried that but the file Zend\zend_ini_scanner.c keeps reappearing every time I do nmake.

Ahh, you're using cygwin. I would suggest you to fetch an express version of Visual Studio, not even sure it is possible to build PHP with cygwin nowadays. We also have this doc https://wiki.php.net/internals/windows/stepbystepbuild .  

Whereby cygwin is known to break VS sometimes, at least one should count with a possibility. So if having some weird errors, it's probably sign for that.

Btw that file should reappear, it's being generated. I just thought it were some switch between ts/nts which could have left that file not updated. But with cygwin, it's unlikely to get support nowadays, i guess.

Thanks.

Hi, 

Thanks for the response.
I followed the steps mentioned here only 
https://wiki.php.net/internals/windows/stepbystepbuild
I do have cygwin installed but it wasn't really for building PHP.
However, I realized that during configure step, it would take utilities such as bison from cygwin directory instead of taking it from default path.
I removed cygwin temporarily for that.
I cleaned everything, started fresh, with buildconf, configure and nmake but I am still getting same error in zend_ini_scanner.c

Hello Again,

Cygwin indeed messed up the current build environment.
On top of that, nmake clean and removing cygwin temporarily did not appear to be enough to start fresh.
I logged out and logged in again to the system to make sure that changes to windows PATH are in effect. Deleted the previous source dir and extracted it again from the archive.
Then followed the usual steps
buildconf
configure (Noticed that bison n other utilities were picked up from their default path)
nmake
I was able to build successfully.
Thanks for pointing me out to cygwin whose utilities did cause the problem.

Thanks for the update. I think this ticket can be closed now.

Yeah, cygwin and VS collide quite often. Probably better to hold them on separate VMs or alike, except a few cases it's justified.

Thanks.
