Error at the time of compiling netmap-fwd on -CURRENT

[Kevin Bowling]

Hi,

The DPRINTF macro in netmap-fwd is defined as #define *DPRINTF*(_fmt,
args...) if (verbose) dprintf(_fmt, ## args)

while  dprintf is defined as dprintf(int fd, const char * restrict format,
...); in stdio.h

You could try, simplistically, to change DPRINTF macro to #define
*DPRINTF*(_fmt,
args...) if (verbose) printf(_fmt, ## args)

to get going but there is likely more to the story.


Regards,
