:: B and C Splines library for AMPL

:: Making the library

1. Get the solvers.tar file from the internet (AMPL interface routines).

2. Get the Splines source file.

3. Make the splines.dll library by typing
   gcc -o splines.dll -shared splines.c  (Linux)
   or
   link -dll -def:splines.def -out:splines.dll @splines.lbc (MSDOS, Visual C/C++).
   The splines.c includes a header file from the solvers.tar AMPL package, so one must provide it  (change to the directory where the solvers.tar was extracted or use the -I flag in the gcc command).

:: Using the library

1. Get or make the library splines.dll.

2. Set the environment AMPLFUNC variable to the library path (export AMPLFUNC=splines.dll in the bash shell). AMPL reads a default library named funcadd.dll or accepts a flag (-i) with a library filename. An alternative is to rename the file splines.dll to funcadd.dll or to call AMPL with the -i splines.dll flag.

3. Use the Splines function as described in this SIPAMPL manual.
