Compile LibXML2 from source

Get the source code from
http://xmlsoft.org/downloads.html

Linux and Solaris
(Have to use python 32-bit)

cd /opt/mydir/libxml2
mkdir linux-gcc3
gunzib -c libxml2-2.9.4.tar.gz | tar xvf –
cd libxml2-2.9.4
./configure --prefix=/opt/mydir/libxml2/linux-gcc3 --enable-static --disable-shared 2>&1 | tee conf.log
## 64 bit
## ./configure CC="cc -m64" --prefix=/opt/mydir/libxml2/linux-gcc3 --enable-static --disable-shared 2>&1 | tee conf.log
make 2>&1 | tee make.log
make install

If you have Python 2.5 or older, you have to replace all these lines:

libxml2-2.9.4/python/generator.py

From

except IOError as msg:

To

except IOError, msg:

Windows
Machine must have Microsoft Visual Studio 2010

Extract source code to C:\mydir\libxml2

Create a directory C:\mydir\win64

Go to C:\mydir\libxml2\libxml2-2.9.4\win32

(In libxml2-2.9.2, copy the configure.ac to configure.in) (Maybe it's a bug?)

Open command prompt:

cscript configure.js compiler=msvc iconv=no zlib=no debug=no prefix=C:\mydir\win64

# For 64 bit, run this command first:
%comspec% /k ""C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"" amd64

nmake /f Makefile.msvc 2>&1 | tee make.log
nmake /f Makefile.msvc install

After that, we need to copy the C:\mydir\win64\include\libxml2\libxml to C:\mydir\win64\include (OMG?!)
