[xmlsec] Compiling with MSVC 10: thousands of errors

[Josef Kokeš]

Hi!

I could use some help with compiling XmlSec (the latest version 1.2.18) 
on Windows. My original attempts were done using MingW/Msys and these 
failed even before I got to compiling XmlSec (I just couldn't get some 
prerequisites to compile).

With MSVC 10.0, I eventually managed to compile all prerequisites, and 
now I am trying to compile XmlSec itself. The problem is, I keep getting 
thousands of errors in header files:

And so on and so on. After 100 errors the compiler stops and tries 
another file, which fails with similar errors (on different lines, 
though). Searching the archives, I found a 2005 message which seemed 
somewhat relevant 
(http://www.mail-archive.com/xmlsec@aleksey.com/msg02730.html) and the 
answer suggested that the user was using a wrong OpenSSL version. That 
is not the case with my setup, as far as I can tell.

I am using a clean Windows XP SP3 install with a clean Microsoft Visual 
Studio 10.0 Express on it. I compiled the following packages (in listed 
order):

- Zlib 1.2.5 - I used the supplied win32\Makefile.msc
- Iconv 1.13 - this one gave me headaches until I learned that I can 
build it using MingW and then copy the .a files to .lib files for MSVC 
to use. Maybe this is the cause of my problems? But what else am I 
supposed to do, considering that Iconv doesn't support MSVC anymore?
- LibXml2 2.7.8 - with configure.js options compiler=msvc zlib=yes debug=yes
- LibXslt 1.1.26 - with configure.js options compiler=msvc zlib=yes 
debug=yes
- OpenSSL 0.9.8r - with configure option VC-WIN32, build batch 
ms\do_masm and makefile ms\ntdll.mak
- XmlSec 1.2.18 - with configure.js options crypto=openssl unicode=no 
debug=yes. I also tried crypto=openssl=098, under the influence of the 
2005 message

What can I possibly do to fix this problem? The files with errors listed 
seem OK to me, but I am not a C programmer so maybe I am missing 
something obvious.

Thanks,

Pepak
