Dear John,


Yes, it's possible to cross-compile libbiosig on linux for windows.
Usually, I do this with mxe.
   git clone https://github.com/schloegl/mxe.git
   cd mxe
   make libbiosig

The approach if "make -f Makefile.win32" is not supported anymore, but
should be replaced with something like
    TARGET=$(TARGET) CROSS=$(TARGET) make libbiosig

Currently, I'm trying with the attached makefile which I put into
    mxe-octave/src/libbiosig.mk
and apply to attached patch

When trying to run
    mxe-octave$ make libbiosig
it does not do much. Any idea what else is needed ?


Best, Alois
