TCL-UDP: Problems compiling a modified version (by the developer) of the package

Hello,
I'm having some problems compiling the (yet to be released) source for
tcludp (that supports multiple interfaces) and I was wondering if I
can get some help? I installed gcc on my Linux and I downloaded all
the TCL source code. I compiled TCL. That was more of an exercise than
anything else, I already have TCL/TK and some pacjkages installed,
just wanted to get set up to compile this package (tcl_udp) because I
recieved source from the developer. He did include a compiled version
but it's for WIN and I have Linux.

The first problem I had was that there seemed to be files missing from
the zip that was sent as compared to a release 1.0.8 of the same
package. I understand this because it's not released yet. So, I copied
all the files from the release 1.0.8 into the directory structure
under /home/user-name/src/tcludp1.0.8, I renamed the original source
and header file (1.0.8) to tcl_udp.ext.bak and then copied the 2 new
source files (udp_tcl.c, udp_tcl.h) into the same directory. I did ./
configure, then make. This configure looked okay but I had problems
with the make.

The first problem was that I am trying to compile in Linux but during
make it appears NOT to follow the #ifdef for LINUX, so I hardcoded
#define LINUX to the top of these two file and compiled again. It
looks better but I still have errors (see below). I'm not a C
programmer, though I took a couple classes. I know a little bit of C
but have not really used it. Even getting this compile to work has
been dificult. I need the .so for Linux.

Another problem thazt I noticed was that there's an error: "'FIONBIO'
undeclared (first use in this function)". I saw another posting about
referencing 'FIONBIO' and relating it to filio.h, but I shouldn't need
that file for Linux - I think. Anyway, there are problems and I have
not been ableo compile it yet. Any help would be appreciated.

Here is the detail iof my set up.

Platform: Linux
Compiler: gcc
