I don't have the references near me at the moment.... But it tells you
a possible solution. Did you try passing -fPIC to gcc (as a $CFLAGS or
whatever in the makefile).
I tend to use this flag whenever I make a shared library on a PPC
(Linux). From the gcc man page:
-fPIC
If supported for the target machine, emit position-independent
code, suitable for dynamic linking and avoiding any limit on the
size of the global offset table. This option makes a difference on
the m68k, PowerPC and SPARC.
Position-independent code requires special support, and therefore
works only on certain machines.
Previously on using -fpic
-fpic
Such code
accesses all constant addresses through a global offset table
(GOT). The dynamic loader resolves the GOT entries when the pro-
gram starts (the dynamic loader is not part of GCC; it is part of
the operating system).
Sorry I have tottally forgotten the reasons why and tend to refer to it
as compilere voodoo...
