gEDA-user: Using iVerilog with fileio

["L. Russell-Morris" <leebrm@extensil.com>]

I have been trying to use Chris Spears fileio (http://chris.spear.net/pli/fileio.htm) with iverilog, I currently have the fileio 
working with VCS, and am trying to set up iverilog in the same environment. When I try to compile the fileio into a iverilog 
module, using iverilog-vpi I get:

	Making fileio.vpi from  fileio.o...

When I remove the -shared in the LDFLAGS argument for the linker I get:

	Compiling fileio.c...

	tf_setworkarea                      fileio.o
	ld: fatal: Symbol referencing errors. No output written to fileio.vpi
	collect2: ld returned 1 exit status

So it appears to be a library issue. Anyone come accross it before or any ideas?
