how to resolve compiling error -- makefile

I have modified a makefile and trying to compile a project. But it is failing in fist step only.

Even i have specified pattern rule for compiling, w.r.t :--
http://www.gnu.org/software/make/manual/make.html#Static-Usage

Makefile is :--

# topdir for wxWidgets base 
top_builddir = /opt/wxgtk
EXTRALIBS = -pthread -lz -ldl -lm
LDLIBS = ${APPEXTRALIBS} ${top_builddir}/lib/libwx_baseu-2.8.a ${EXTRALIBS}
CXX         = c++

CXXFLAGS = -g -O0 -pthread -I/usr/include/SDL -D_REENTRANT -Wall -Wno-ctor-dtor-privacy
CPPFLAGS = -D__WXDEBUG__  -I${top_builddir}/wx/include/base-unicode-release-static-2.8  -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D_LARGEFILE_SOURCE=1
CFLAGS = ${APPEXTRACFLAGS} ${CPPFLAGS} -O2 -MMD -pthread -Wall
CFLAGS  += -DLINUX

CANALOBJS =     ../../common/listenthread_unix.o ../../common/clientthread_level1_unix.o ../../common/devicethread_unix.o \
        ../../common/canalshmem_level1_unix.o ../../common/clientlist.o ../../common/controlobject.o \
        ../../common/devicelist.o ../../common/udpreceivethread_unix.o ../../../vscp/common/vscp.o \
        ../../common/clientthread_level2_unix.o ../../common/canalshmem_level2_unix.o \
        ../../common/tcplistenthread.o
CANALHDRS = ../../common/clientlist.h ../../common/controlobject.h ../../common/devicelist.h \
        ../../common/canal.h ../../common/canaldlldef.h \
        ../../common/version.h ../../common/canal_unix_ipc.h ../../common/CanalShMem_level1_unix.h \
        ../../common/CanalShMem_level2_unix.h ../../common/clientthread_level1_unix.h ../../common/clientthread_level2_unix.h
PROJOBJS    = ../../../common/dllist.o ../../../common/configfile.o ../../../common/crc.o
PROJHDRS    = ../../../common/dllist.h ../../../common/configfile.h
OBJS        = canald.o
HDRS        = canald.h

all:        canald

# Build the Linux executable
canald:     $(OBJS) $(HDRS) $(CANALOBJS) $(CANALHDR) $(PROJOBJS) $(PROJHDRS)
        $(CXX)  -o canald $(OBJS) $(CANALOBJS) $(PROJOBJS) -L$(LIBS) $(LDLIBS)

$(OBJS) $(CANALOBJS) $(PROJOBJS):%.o: %.cpp
        $(CXX) -c $(CFLAGS) $< -o $@

error i am getting :--

make
make: *** No rule to make target `canald.cpp', needed by `canald.o'.  Stop.

Please suggest how to resolve this error ?

EDITED :-------

file was missing... its compiling ... but getting following error

vscpd.cpp:47:19: fatal error: wx/wx.h: No such file or directory
compilation terminated.
make: *** [vscpd.o] Error 1

I have installed wxgtk at following location :---

/opt/wxgtk

.profile is modified :--

PATH = $PATH:/opt/wxgtk
export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/usr/local/lib/pkgconfig:/usr/lib/pkgconfig:/opt/wxgtk/lib:$LD_LIBRARY_PATH

Make is not able to find 

#include<wx/wx.h>

How to resolve it ?

You must use wx-config instead of specifying the include paths directly, see e.g. this answer.

Your makefile is pretty strange as you define CXXFLAGS only to never use it and instead use CPPFLAGS as part of CFLAGS. So in your case you need to replace CPPFLAGS definition with a wx-config invocation, e.g.

WX_CONFIG := /opt/wxgtk/bin/wx-config
CPPFLAGS := $(shell $(WX_CONFIG) --cxxflags)

Better, get rid of CPPFLAGS and define CXXFLAGS like this and use it.

Also update your LDLIBS to use wx-config too:

LDLIBS := ${APPEXTRALIBS} $(shell $(WX_CONFIG) --libs)

(EXTRALIBS shouldn't be normally needed at all any more).
