Hi Sebastien,
Thanks - I got this to compile with the
optioons you have mentioned. Found a couple of issues - one of which I was
able to resolve easily:
1. In the path: linux/scripts/mod/libelfbuild/libelf there is a file called
INSTALL which is a readme. This needs to be renamed for the compilation to
work in a cygwin env.
The makefile tries to create a directory called install in the same
subdirectory as above and crashes out.
2. The GDB expcts the symbol _fstack to be defined - which is defined in the
linker.ld files of the milkymist database - but for linux I could not do
this - this prevents from loading the simulator ( error as below )
bash-3.2$ ./gdb.sh

(gdb) target sim --memory-region 0x00000000,0x0fffffff
Failed to find symbol _fstack in program. You must specify memory regions
with --memory-region.
unable to create simulator instance
(gdb) Quit
Any ides to fix this?
Thanks.
Regards,
Gautam
