Compiling php_excel and LibXL on Windows

I'm trying to build PHP on Windows together with a popular C library for Excel manipulation, LibXL. This library has a native PHP object-based extension called php_excel. I'm attempting to build the latter as a shared DLL on Windows, rather than statically compiling it into PHP for distribution.

My starting point for compilation is the PHP buidling for Windows w开发者_开发技巧iki entry and I'm using Visual Studio 2008 and the Windows SDK 6.1 as recommended. For the purposes of further paths in this explanation, my reference directory is c:\php-sdk\php53dev\vc9\x86\. References to the PHP snapshot are shown as the folder php5.3-x where x is the snapshot build datetime.

After the extraction of the PHP snapshot, I'm adding bin\libxl.dll, include_c\* and lib\libxl.lib to the respective folders in deps.

I then extract the php_excel extension into php5.3-x\ext\excel-0.9.1.

Running buildconf and configure --help reveals that the extension is being seen. I'm then running:

configure --disable-all --enable-cli --with-excel=shared --disable-zts --disable-isapi --disable-nsapi
nmake

To achieve a VC9 non-thread-safe build of the DLL.

On nmake, I'm coming up against syntax errors for every header file in LibXL:

c:\php-sdk\php53dev\vc9\x86\deps\include\enum.h(4) : error C2061: syntax error: identifier 'libxl'
c:\php-sdk\php53dev\vc9\x86\deps\include\enum.h(4) : error C2059: syntax error: ';'
...

and syntax errors in the excel.c source for php_excel:

ext\excel-0.9.1\excel.c(33) : error C2146: syntax error : missing ')' before identifier 'f'
ext\excel-0.9.1\excel.c(33) : error C2061: syntax error : identifier 'f'
ext\excel-0.9.1\excel.c(33) : error C2059: syntax error : ';'
ext\excel-0.9.1\excel.c(33) : error C2059: syntax error : ')'
...

Here, for example, are these two sections from the respective files:

enum.h

#ifndef ENUM_CPP_H
#define ENUM_CPP_H

namespace libxl { # line 4
    ...
}

excel.c

#ifdef HAVE_CONFIG_H
#include "config.h"
#endif

#include "libxl.h"
#include <stdlib.h>

#include "php.h"
#include "php_ini.h"
#include "ext/standard/info.h"
#include "ext/date/php_date.h"
#include "php_excel.h"
#include "zend_exceptions.h"

static long xlFormatBorder(FormatHandle f) # line 33
{
    return 1;
}

I don't see syntax errors but assume I am missing an obvious step somewhere?

I made the build and pulled a request to fix the build. See the bins here http://www.php.net/~pierre/
