I also tried to build the Synthetic Linux target on Ubuntu, and succeeded the
build on Ubuntu 9.

However, when trying to execute the tests, I ran into numerous problems. First
I hacked the linker script to match the Ubuntu memory map, and finally the
generated elf images matched the headers of a natively built executable.

However it looks like the Ubuntu ABI is significantly different from the one
assumed in eCos.

So I also hacked the startup.S to no longer try to get the argc, argv, and
environment. 

After this I reached the _linux_entry point, but when the synth_hardware_init()
where the code again crashed.

As I said, it looks like there are significant differences between the current
Ubuntu releases and the code in eCos.

Regards,

Liviu
