Re: [Xen-devel] cross compiling 32 bit Xen on an x86_64 system

I came across a variant of this problem trying to cross-compile

there is no way to redirect it to another compiler when trying to build
these modules. In other words, python seems not to be able to
cross-compile these things.
One option would be to use vm-tools instead of xend (search this list
for announcements and URL), as the former does not (yet) depend on
Python.
I found the best way to deal with building python modules is the following:
PYINC=`python -c "import distutils.sysconfig; print
distutils.sysconfig.get_python_inc()"`
PYLIB=`python -c "import distutils.sysconfg; print
distutils.sysconfig.get_python_lib(prefix='')"`
CFLAGS += -I$(PYINC)
And then to use $(DESTDIR)$(prefix)/$(PYLIB) for the install path of the
module. You have to write your own rules to build the shared object but
at least you don't have these cross-compiling issues.
This is how the python bindings are built in libxen.
