Re: Help with running embedded standalone program v 6.4.0

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octave directory was in the PATH but was superseded by other directories.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!
