Re: [INTERNALS-WIN] Developing PHP extensions on Windows with VC++, linking problems

Hi all,
thanks for your kind replies; I tried to follow your advices but I 
still have problems.

I tried to compile PHP on win (without my extension) following the 
tutorial you pointed me out 
http://blog.harddisk.is-a-geek.org/index.php/dev/php/php-on-windows/ 
and everything seems to work (I haven't tested the PHP release built 
however, but I didn't get error messages).

I then created under /ext a folder /my_extension and put there all 
the files and folder produced by visual studio when I created my 
custom extension following the tutorial 
http://www.talkphp.com/vbarticles.php?do=article&articleid=49&title=creating-custom-php-extensions:
- release (folder)
- debug (folder)
- dllmain.cpp
- ReadMe.txt
- my_extension.cpp
- my_extension.vcproj
- my_extension.vcproj.MYCOMPUTERNAME.MYNAME.user
- my_extension.vcproj.MYCOMPUTERNAME.MYUSERNAME.user
- stdafx.cpp
- stdafx.h
- targetver.h

I then created a file config.w32 in the same folder, the file 
contains just one line:
EXTENSION(my_extension, 'my_extension.cpp', false);

I then builconf and configure --disable-all --enable-cli, following 
http://blog.harddisk.is-a-geek.org/index.php/dev/php/php-on-windows/...no 
errors and at the end of the process my_extension resulted in the 
static enabled extensions.

I then execute nmake but I get this error:
internal_functions.c
main\internal_functions.c(43) : error C2065: 
'phpext_my_extension_ptr' : undeclared identifier
main\internal_functions.c(43) : error C2099: initializer is not a constant

I don't have any idea about the cause...

Can you help me?

Thanks.

Eugenio
