Alex,
I was having problems with unresolved references.
I put libc, libm, and ld-2.0.7.so in my /lib fdirectory.
It was kind of big, so I ran the strip command on it, and it shrank way down and
fits nicely on the Helio:
ls -l /opt/tvt/helio-image/root/lib/
total 1624
-rwxrwxr-x 1 root root 361302 Jan 29 14:42 ld-2.0.7.so*
lrwxrwxrwx 1 root root 11 Jan 30 15:51 ld.so.1 -> ld-2.0.7.so*
-rwxr-xr-x 1 root root 991360 Jan 29 14:15 libc-2.0.7.so*
lrwxrwxrwx 1 root root 13 Jan 30 15:51 libc.so.6 ->
libc-2.0.7.so*
-rwxr-xr-x 1 root root 287572 Jan 29 14:15 libm-2.0.7.so*
lrwxrwxrwx 1 root root 13 Jan 30 15:51 libm.so.6 ->
libm-2.0.7.so*
I think the trick is to strip the shared library after it is built.
For example, trying:
file /lib/libc-2.1.3.so
on my Mandrake 7.2 system returned:
/lib/libc-2.1.3.so: ELF 32-bit LSB shared object, Intel 80386, version 1,
stripped
I do not remember stripping them myself, (although I may have accidently)
