Hello and Thanks you for openning this message.


I'm working on a chip-card reader running on parrallel port this program
works under linux red hat, using the command line :
-> gcc myprog.c -omyprog -O2
and
->/myrep/myprog


but when I try to compile it under cygwin )))-: it doesn't works


BASH.EXE-2.02$ pwd

-------------------------------------------------------------------------

this is the lib I need

ORIGINAL LINE     : #include <asm/io.h>
have tried to use : #include </io.h>
or                : #include <mingw32/io.h>

where can I find the the equivalent of red hat "asm/io.h"
and where sould I copy it under cygwin ?

The following is myprog.c (fastly commented) source it will be usefull to
understand what I say.

Tank you

Regards Bruno
