Hi,

I am trying to compile the code base while adding  the following flags

GCOV_CFLAGS = -fprofile-use -fprofile-arcs -ftest-coverage -fprofile-generate

CXXFLAGS = $(DEBUGOPT) -m32 -pipe -fexceptions -fPIC -Wno-deprecated
$(GCOV_CFLAGS) $(CXXDEFINES) $(CXXINCLUDE)
CCFLAGS = $(DEBUGOPT) -m32 -pipe -fexceptions -fPIC $(GCOV_CFLAGS) 
$(CXXDEFINES) $(CXXINCLUDE)


LDLIBS = $(ALAEXTLIB) $(SCS_LIB) $(ORB_LIB) $(APP_LIBDIR) $(APP_LIB)
$(NELLIBDIR) $(TCL_LIB) -lgcov  

LDFLAGS = $(DEBUGOPT) $(GCOV_CFLAGS) -fPIC -m32 -s -O -shared  -lgcov

I can get rid of this error while removing fprofile-arcs..so I am getting this
error if I add -fprofile- flags.

I did search in google and tried as much as I could however still the same..
Please guide me on the way to fix this errors. 

Thanks.
