Re: gEDA-user: PCB adding exporter GUI
I modified the Makefile.am but Make still complained, so I tried with
makefile.in and this time it went through compilation; now the linker
(I suppose) can't find hid_png_init reference in hidinit.o. This is
strange, as I didn't modify hidinit.c.
Maybe I should reconfigure with some magic parameter, but which one?
I'm making an exporter to gcode, so that I can mill my pcbs without
chemicals; I think it should be kept separate from the main png
exporter.
Thank you for your help,
Alberto
