Hello Please see the long discussions about the fixed package.

The problem with the dll approach (whether it's cygwin, mingw or MSVC) is that it does not integrate well with the package manager. To be usable, the dll must be installed in a location where the Win32 system can find it, in order to load the oct-file correctly (the fixed oct file will be linked against the dll). Putting the dll in the same directory of the oct file is not enough, it should be installed in a location available from PATH. To solve this problem, several solutions can be considered: 1) the package manager installs the DLL into a location that is part of PATH, for instance the octave bin directory; this is not currently supported by the package manager 2) install the DLL in the same directory of the oct file, and make octave dynamic loader add that directory to PATH before trying to load the oct-file 3) do not use a DLL; use a static library and link the oct file against it After some discussion (a few months ago), I chose the 3rd option, as it could be implemented locally in the fixed package. Moreover, by making the oct-file export the same symbols as the DLL, I could completely remove the need for a DLL (as any code that needs to be linked against the DLL can be linked against the oct-file instead).
