Interfacing octave with C#

Question

I have developed a program in Octave to which I would like to add a GUI layer. I want to create an executable program in C# that I can distribute but want to stick with the

Answer 1

To build a standalone: http://www.gnu.org/software/octave/doc/interpreter/Standalone-Programs.html#Standalone-Programs

I have a similar problem, which is to create a .dll for C# I've been looking for a way to do this for a while now, I have not been able to find instructions or an easy way to do it. This is more an ongoing project than a question, but I' d definitely take any answer or help!:)

I am planning to keep track of my efforts here, so at the end this should become a page that will allow people to find how to compile octave into a .dll ( always assuming this is possible)

So:

-I am using VS2010

-I started with the MS VS2010 compiled binaries for octave, assuming this will be closer.

-I created a project in VS and used the following code:

#include 
#include 
#include 
#include 


int main(int argc, char* argv[])
{
    std::cout<<"hello world"<>a;
    return 0;
}

-The code would of course not find the octave libs, so I added them, e.g.,

C:\Octave\Octave-3.6.1-VS10\lib\octave\3.6.1;C:\Octave\Octave-3.6.1-VS10\include\octave-3.6.1;C:\Octave\Octave-3.6.1-VS10\include;$(VCInstallDir)include;...

To Include Directories (Right click on Project-->Properties)

Now I get

Error   73  error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall octave_value::~octave_value(void)" (__imp_??1octave_value@@QAE@XZ) referenced in function "public: void * __thiscall octave_value::`vector deleting destructor'(unsigned int)" (??_Eoctave_value@@QAEPAXI@Z)    ...\Projects\cppap32\cppap32\main.obj   cppap32

which basically means it cannot find octave_value... By using dumpbin.exe we can see that it needs to have both octave.lib AND octinterp.lib

It now does compile.... :)

Next step create a .dll ...

Notes:

To check what is exported by a .lib:

dumpbin.exe /exports C:\Octave\Octave-3.6.1-VS10\lib\octave\3.6.1\octave.lib
