[cells-gtk-devel] Problems with demo

[Leonardo Varuzza]

I have the same error executing the demo with SBCL 1.0.13.53 in
Unbuntu 7.10 AMD64.

Another problem occur when compiling gtk-ffi:

/usr/bin/ld: gtk-adds.o: relocation R_X86_64_32 against `a local
symbol' can not be used when making a shared object; recompile with
-fPIC
gtk-adds.o: could not read symbols: Bad value

I need to use -fPIC option to compile the library.
