That sounds right so far - at least the compiler is working.

Copy the libxil.a file from a windows EDK installation into the linux 
toolchain.  Under windows, it lives in /edk/sw/lib/microblaze/

Assuming you installed the linux tools into 
/usr/local/microblaze-elf-tools, then you want to place libxil.a in 
/usr/local/microblaze-elf-tools/microblaze/lib/

That fixes the "can't find -lxil" message, however you will also need to 
compile and link the various libraries that the EDK normally creates in 
an EDK project directory.  Look at the makefile that EDK creates 
(normally called system.make or similar), and find the "program:" 
target, you should see what other files must be specified.  They will 
live somewhere like [projectname]/microblaze_0/libsrc

This is not a problem when linking uclinux-targeted programs because all 
of the necessary libraries are provided by uClibc, which is the C 
library we use for uclinux.

Let me know if you still have problems - I haven't tried making "normal" 
edk microblaze programs under Linux, but I'm sure it can be done.

Note that when EDK6.1 comes out (I think end of septerm is target 
release date?), it will have native linux support anyway, so all of this 
should become unnecessary.

Regards,

John
