[Nbd] NBD with uClibc 0.9.33.2 - compile problem

[VAGO Tibor <tibor.vago@...17...>]

Hi,

I tried to compile nbd 3.2 on my NAS, an ARMv5T based system. I install 
gentoo-uclibc on it and when I try to compile nbd it cannot find 
fallocate() function:

------------------------------------------------------------------------
armv5tel-softfloat-linux-uclibceabi-gcc -std=gnu99 -w -Os -march=armv5te 
-fomit-frame-pointer -pipe -I/usr/include/glib-2.0 
-I/usr/lib/glib-2.0/include   -w -Os -march=armv5te -fomit-frame-pointer 
-pipe  -Wl,-O1 -Wl,--as-needed -o nbd-server nbd_server-nbd-server.o 
-lglib-2.0 -lintl
nbd_server-nbd-server.o: In function `exptrim':
nbd-server.c:(.text+0x2274): undefined reference to `fallocate'
collect2: ld returned 1 exit status
------------------------------------------------------------------------

In configure I can't see any check for fallocate() availability. It just 
found fcntl.h and it assumes there is fallocate() function?

In uClibc there is posix_fallocate() and there is no fallocate().
I don't know what are the differences between posix_fallocate() and 
fallocate() but if it is equivalent may I use it?

Regards,
Tibor
