Installing libxml2 with NestedVM

Prequisites

curl

darcs

Install NestedVM

First, install NestedVM:

$ git clone http://nestedvm.ibex.org/.git/
$ cd nestedvm.ibex.org
$ make
$ make env.sh
$ . env.sh
$ cd ..

libiconv

Then install libiconv:

$ mkdir $HOME/local
$ wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
$ tar zxvf libiconv-1.13.1.tar.gz
$ libiconv-1.13.1
$ ./configure --host=mips-unknown-elf --prefix=$HOME/local
$ make && make install
$ cd ..

libxml2

libxml2 must be patched before you can compile it with NestedVM. The patch is very simple though, and I'll include it here.

$ wget ftp://xmlsoft.org/libxml2/libxml2-2.7.6.tar.gz
$ tar zxvf libxml2-2.7.6.tar.gz
$ cd libxml2-2.7.6

This is the part where you must patch libxml2. I've included the diff below.

$ patch -p0 < fix.patch
$ ./configure --prefix=$HOME/local \
  --without-zlib \
  --host=mips-unknown-elf \
  --without-http \
  --without-ftp \
  --without-python \
  --with-iconv=$HOME/local
$ make && make install

You should now be ready to write C programs that cross compile against libxml2 on NestedVM. Check out this page for more info.
