[PD] compiling hidio for Windows

Sun Feb 2 18:38:41 CET 2020

You are right! I now have undefined references only on hidio.o:

hidio.o: In function `hidio_write_event':
Z:\Desktop\hidio/hidio.c:357: undefined reference to `hidio_write_event_symbols'
Z:\Desktop\hidio/hidio.c:336: undefined reference to `hidio_write_event_ints'
Z:\Desktop\hidio/hidio.c:347: undefined reference to
`hidio_write_event_symbol_int'
hidio.o: In function `hidio_setup':
Z:\Desktop\hidio/hidio.c:643: undefined reference to `hidio_devices'
Z:\Desktop\hidio/hidio.c:644: undefined reference to `hidio_elements'
hidio.o:hidio.c:(.rdata$.refptr.hidio_elements[.refptr.hidio_elements]+0x0):
undefined reference to `hidio_elements'
hidio.o:hidio.c:(.rdata$.refptr.hidio_devices[.refptr.hidio_devices]+0x0):
undefined reference to `hidio_devices'
collect2.exe: error: ld returned 1 exit status

The build system for Windows seems to be broken and needs to be fixed (and probably switched from automake to pd-lib-builder). Unfortunately, I don't have time right now to work on this, but you could file a bug report on the GitHub repo, so maybe the maintainer will do it.
