Re: More on API for Octave

[ldoolitt]

OK.  This is what I have so far - it's ugly, but basically working.

Machine 1: octave-2.0.5 binaries from RedHat 4.2 installed
Makefile as follows:

--cut here--
OCT_BASE=/usr/include/octave
OCTAVE_INCLUDES=-I${OCT_BASE}
CC=gcc
CFLAGS=-Wall -O
CXX=g++
CXXFLAGS=-Wall -O ${OCTAVE_INCLUDES}
OCTAVE_LIBS=-loctinterp -loctave -ltinst -lcruft -lOctaveReadline -lkpathsea
FLIBS=-lf2c -lgcc
TERMLIBS=-lncurses
CXXLIBS=-lg++ -ldl
OBJFILES = data.o ols.o rank.o analyze.o
testme: data.o ${OBJFILES}
        ${CXX} -o testme ${OBJFILES} ${OCTAVE_LIBS} ${FLIBS} ${TERMLIBS} 
${CXXLIBS}
--cut here--

Results in

Machine 2: octave-2.0.11 unpacked and built on a Red Hat 4.2 Linux system,
but not installed (I'm not root).  Makefile as follows: 

--cut here--
OCT_BASE=${HOME}/octave/octave-2.0.11
OCTAVE_INCLUDES=-I${OCT_BASE} -I${OCT_BASE}/src -I${OCT_BASE}/liboctave 
-I${OCT_BASE}/libcruft/misc

CXXFLAGS=-Wall -O ${OCTAVE_INCLUDES}
OCTAVE_LIBS=-L ${OCT_BASE}/liboctave -loctave -L ${OCT_BASE}/libcruft -lcruft
FLIBS=-lf2c -lgcc -loctave

testme: data.o ${OBJFILES}
        ${CXX} -o testme ${OBJFILES} ${OCTAVE_LIBS} ${FLIBS} ${CXXLIBS}

The typical includes for my c++ files are
#include <config.h>
#include <oct-obj.h>
#include <utils.h>
#include <iostream.h>

I guess I must be doing something right, because they both get the right
answer :-)

Here's my to-do list:
   Repeat some of this on HP-UX
   Make a shared library with just the math parts of liboctave
   Tons of non-octave related stuff :-(
