[Xen-devel] Build shared library (.so) for Mini-OS

["Yiming Zhang" <sdiris@xxxxxxxxx>]

Dear all,

I want to realize dynamic library linking/loading for Mini-OS. The first
step is to build a shared libc library (.so) from newlib-1.16.0. To achieve
this, I modified the stubdom/Makefile to:

(i) build all obj files (libc_objs = *.o) with -fPIC option, and 
(ii) tried to do "gcc -shared -o libc.so $(libc_objs)"

However, the 2nd step cannot work because "string/memcpy.o" and
"machine/x86_64/memcpy.o" both have a memcpy() function. Is there any way to
build a shared libc library (.so) from newlib? (and how this problem is
addressed for standard glibc?) Thank you!

Cheers,
Yiming
