[rrd-users] v1.3 on FreeBSD

[Steven Hartland]

Anyone had any luck getting v1.3 to compile cleanly on FreeBSD?

The first error was the one described here about
read-only variable 'ordering':
http://www.mail-archive.com/rrd-developers@lists.oetiker.ch/msg02057.html

Quite a simple fix.

The next one however is:
rrd_open.c: In function `rrd_open':
rrd_open.c:178: warning: implicit declaration of function `madvise'
rrd_open.c:178: warning: nested extern declaration of `madvise'

rrd_open.c:504: warning: nested extern declaration of `fdatasync'
rrd_open.c: At top level:
rrd_open.c:278: warning: 'mincore_print' defined but not used

Which doesnt seem to be simple :(

>From what I can tell these are defined in sys/mman.h but are guarded
by __BSD_VISIBLE which is automatically set in sys/cdefs.h depending
on the values of _ANSI_SOURCE and _C99_SOURCE and as the Makefile
is defining -std=c99 I assume this is why the are unavailable.

Using the dirty hack of adding them in manually I then hit:
./.libs/librrd.so: undefined reference to `fdatasync'

It seems fdatasync doesnt exist on FreeBSD only fsync. My fix
here was to change fdatasync to fsync under #ifdef __FreeBSD__
in both rrd_open and rrd_create

Any advice on these issues appreciated.
