Yes.

The RAM build (and most other builds) are using the compiler flags -fpic 
and -msingle-pic-base. So this should be fine.

As far as I know (I have read some howto with google), dynamic linking 
is working with uCLinux + glibc and "non-working" with uCLInux and 
uClibc. "non-working" because you have to add static IDs to the dynamic 
libraries, and this will in turn lead to code bloat.

So I have decided against having shared libs. The "applets" in PIXIL are 
so small that it doesn't matter to link them all together in the 
executable. All we must do is to add a prefix to the non-static 
functions, and do some sort of applet registration.

Do you have evidence that shared libs are working fine in uCLinux + 
uClibc + FLT binaries?
