This is more an ongoing project than a question, but I' d definitely take any answer or help!:) </p> <p>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)</p> <p>So:</p> <p>-I am using VS2010</p> <p>-I started with the MS VS2010 compiled binaries for octave, assuming this will be closer.</p> <p>-I created a project in VS and used the following code:</p> <pre><code>#include <iostream> #include <octave/oct.h> #include <octave/octave.h> #include <octave/parse.h> int main(int argc, char* argv[]) { std::cout<<"hello world"<<std::endl; char a[900]; std::cin>>a; return 0; } </code></pre> <p>-The code would of course not find the octave libs, so I added them, e.g.,</p> <pre><code>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;... </code></pre> <p>To Include Directories (Right click on Project-->Properties)</p> <p>Now I get</p> <pre><code>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 </code></pre> <p>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</p> <p>It now does compile.... :) </p> <p>Next step create a .dll ...</p> <p>Notes:</p> <p>To check what is exported by a .lib:</p> <pre><code>dumpbin.exe /exports C:\Octave\Octave-3.6.1-VS10\lib\octave\3.6.1\octave.lib </code></pre> <p>Relevant links:</p> <p>Similar, open question on other site: <a href="http://www.daniweb.com/software-development/cpp/threads/297336/gnu-octave-for-c-how-to-start" rel="nofollow">http://www.daniweb.com/software-development/cpp/threads/297336/gnu-octave-for-c-how-to-start</a></p>
