Re: installation errors of octave-forge parallel on windows

[Hanan Rosemarin]

it seems that the toolboxes supplied in the "src" directory of the windows build are somehow different as it provides the "optim" toolbox without providing the "struct" and "parallel" toolboxes which are required as dependencies when installing online "pkg install -forge optim"

The gnulib implementation of  sys/socket.h (that is used octave build) may help. However, poll.h is also required to build which is not implemented on MinGW and octave's gnulib tree does not implement it.

I tried to implement it but my knowledge is not enough to complete it.
