Kernel Profiling
I compiled my device driver with the profiling option -p but while linking I am getting undefined reference to _mcount.
LD [M] /vobs/femto_drivers/DspBiosLink/dsplinkk/src/dsplinkk.o
Building modules, stage 2.
MODPOST
*** Warning: "_mcount" [/vobs/femto_drivers/DspBiosLink/dsplinkk/src/dsplinkk.ko] undefined!
Architechture: ppc32
From where I can link this _mcount and how to get rid of this issue. Can anyone please guide me.

mlib_ImageDilate4(3MLIB) mediaLib Library Functions mlib_ImageDilate4(3MLIB)
NAME
mlib_ImageDilate4 - four neighbor dilate
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageDilate4(mlib_image *dst, const mlib_image *src);
DESCRIPTION
The mlib_ImageDilate4() function performs a dilation operation on an image by using each pixel's four orthogonal neighbors. The source and
destination images must be single-channel images. The data type can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT.
For 4-neighbor binary images, it uses the following equation:
dst[x][y][0] = OR{ src[x][y][0],
src[x-1][y][0], src[x+1][y][0],
src[x][y-1][0], src[x][y+1][0] }
For 4-neighbor grayscale images, it uses the following equation:
dst[x][y][0] = MAX{ src[x][y][0],
src[x-1][y][0], src[x+1][y][0],
src[x][y-1][0], src[x][y+1][0] }
where x = 1, ..., w-2; y = 1, ..., h-2.
PARAMETERS
The function takes the following arguments:
dst Pointer to destination image
src Pointer to source image.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
