Re: Help with running embedded standalone program v 6.4.0

[ashwin damle]

Hi Markus,

Yes, you are correct. That was the issue. I had copied the liboctave and libinterp DLLs.  I tried with the solution you'd suggested and it worked. 

Alternatively, after your email, I removed the copied DLLs and started searching for a way to not include DLLs in the local executable director. I had already included the Octave bin directory "C:\Program Files\GNU Octave\Octave-6.4.0\mingw64\bin" in the PATH. However, it was not working and had to place the DLL in the working directory. I realised that this octave directory was in the PATH but was superseded by other directories. I move the Octave bin directory up the order. I think this made Windows give preference to the directory and I no longer need to copy individual DLLs in the working directory.

Thank you for the pointer!

IIUC, that symbol demangles to:

std::basic_filebuf<char, std::char_traits<char> >::open(wchar_t const*, std::_Ios_Openmode)

 

That is a symbol that should be exported by the standard libraries.

It looks like you copied some (but not all) necessary libraries to a different folder with the executable. Either, copy the standard libraries to that folder, too, or try compiling with `-static-libstdc++` to check if that makes a difference.

E.g.:

 mkoctfile --link-stand-alone embedded_ashwin.cc -o embedded.exe -static-libstdc++

 

HTH,

Hello,

 

Please note that although the screenshot says callOctave.exe, inside it is the same embedded.cc program. I thought of clarifying.

Hello,

 

I am trying to run the embedded program at Standalone Programs (GNU Octave (version 6.4.0)) - attached.

 

When I execute the program using .exe created using mkoctfile --link-stand-alone embedded.cc -o embedded.exe

 

I get the following error. My computer is Windows 10, Gnu Octave v6.4.0. This was working in the previous version v 6.2.0. Could you please guide.
