Re: gEDA-user: Error Compiling fileio3.6 with iverilog-vpi

Hi,

There are two problems here, I have commented inline about them.

These don't look like fatal errors, they look like re-definitions of
system things that are supposed to be defined in stdio.h.  You can
probably safely remove the duplicate definitions, as you mention below.
They are used as arguments to fseek() and friends.

Now, these are more fatal.  Although Icarus' coverage of VPI is fairly
complete. The PLI interface is not. There are a certain number of PLI
shim functions implemented in libveriuser, unfortunately `tf_sizep()' is
not among them.  If you feel adventurous, I am sure Steve would accept
patches to implement this function.  The place to patch is probably in
the libveriuser subdirectory of the distribution.

If you just want to get it to work, you should be able to fake the call
to tf_sizep() if you already know the size of the thing it's refering
to.  

This function returns the value size in bits of the argument number you
pass it.  If the argument is a string, it returns the string length
instead of the number of bits.  The argument number starts at 1 for the
first argument.
