  Compilation Instructions
================================================================

Configuration
=============

	Before the compilation, a configuration menu will appears allowing
	MOL configuration settings to be tweaked. It is possible to return to
	this menu later by issuing the command 'make menuconfig'.


Building MOL from the source tarball:
======================================

	This is very simple just do

		bash$ ./autogen.sh
		bash$ make		
		bash$ make install	(as root)

During the compilation, a configuration menu will appear allowing various
optional features to be turned on or off. It is possible to revisit this
menu later by issuing 'make menuconfig'.  The 'make defconfig' command
sets the default configuration.


The kernel source
=================

	MOL uses a couple of kernel modules (the core MOL engine and networking
	related modules). It is very important that kernel modules are compiled 
	using the correct kernel headers. Kernel modules should *always* be 
	compiled using the same headers as was used to build the kernel. If 
	headers from a different kernel version is used (or even from a 
	different kernel configuration), then the result will probably not be a
	usable kernel module.

	Assuming the currently running kernel is 2.6.1-rc1, MOL expects the symlink

		/lib/modules/2.6.1-rc1/build

	to point to the kernel headers used when the kernel was built. This symlink
	is normally created during the 'make modules_install' step of the kernel
	build process.

	If the symlink above does not exist, then MOL looks for the kernel source
	in /usr/src/linux. It is possible to instruct MOL to look at an alternative
	location by compiling MOL as follows:

		make KERNEL_SOURCE=/path/to/kernel/source
		make install
	
	Warning: It is quite common that distributions ship broken kernel headers.
	If that is the case, the easiest solution probably is building a custom kernel.


Building RPMs
=============

	There are built-in targets for generating RPMs. The following makefile
	targets are available:

	   rpms:     	Builds mol and mol-kmods
	   kmods_rpm:	Builds mol-kmods
	   mol_rpm: 	Builds mol

	It is possible to include support for more than one kernel version 
	by putting all the kernel source trees in the directory THE_DIR and do

	   bash$ make kmods_rpm KERNEL_TREES=THE_DIR

	Similarly, to rebuild the mol-kmods.src.rpm with support for
	all the kernels in THE_DIR

	   bash$ rpm --rebuild mol-kmods.src.rpm --define 'kernel_trees THE_DIR'


Running MOL
============

	The directory '/etc/mol' contains various runtime-settings
	(which volumes to use etc). Taking a look at these config files
	is probably worthwhile.

	IMPORTANT: The 'make install' step does _not_ overwrite config files
	already installed. If an old MOL version is already installed, it might
	be a good idea to take a quick look at the new config files which can
	be found in /usr/[local]/share/doc/mol-0.9.xx/config/.

	After editing the mol config files, start MOL as follows:

		bash$ startmol		(to start MacOS)
		bash$ startmol -X	(to start MacOS X)
