使用Octave库的C ++程序

Question

I try to use in my c++ project libraries from Octave. Unfortunately, I am not able to build program. I use Windows 7 64 bit, Octave3.6.4_gcc4.6.2 and gcc 4.6.2.

My steps:

1. Downloaded Octave3.6.4_gcc4.6.2.exe ( http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.6.4%20for%20Windows%20MinGW%20installer/Octave3.6.4_gcc4.6.2_20130408.7z/download )

Which I installed in C:\\Octave. I have added the address of the bin folder of octave to the environmental variable PATH.

2. Downloaded mingw32-gcc-4.6.2-release-c,c++,fortran-sjlj-FINAL.7z and installed in C drive. I have added the address of the bin folder of mingw to the environmental variable PATH.

3. Tried to compile simple example main.cpp (or example from http://www.gnu.org/software/octave/doc/interpreter/Standalone-Programs.html#Standalone-Programs )

.

#include <iostream>
#include <octave/oct.h>

using namespace std;

int main() {

  return 0;
}

4. I used makefile:

.

OCTAVE_INCLUDE=C:\Octave\Octave3.6.4_gcc4.6.2\include\octave-3.6.4

all: test

clean:
    -rm test.o test

test: test.o
    mkoctfile --link-stand-alone -o test test.o

test.o: main.cpp
    g++ -c -I$(OCTAVE_INCLUDE) -I$(OCTAVE_INCLUDE)octave -o test.o main.cpp

So, we have

hdf5.h: No such file or directory regex.h: No such file or directory

but they are in C:\\Octave\\Octave3.2.4_gcc4.4.0\\include\\

I do not understand where is my mistake.

Answer 1

The solution to my problem was an issue with my gcc version. It seems likely that it was incompatible with the version used to compile octave.

The corrected makefile is below:

OCTAVE_INCLUDE=C:\Octave\Octave3.6.4_gcc4.6.2\include

all: test

clean:
    -rm test.o test

test: test.o
    mkoctfile --link-stand-alone -o test test.o

test.o: main.cpp
    g++ -c -I$(OCTAVE_INCLUDE) -I$(OCTAVE_INCLUDE)\octave-3.6.4 -o test.o main.cpp
