Thanks for your replies. I haven't fixed this yet.

Here is the essence of my makefile (which makes a static library):
====================================================
# List the object files that comprise this library
OBJFILES = ErrorHandler.o \
EnvVars.o \
EVD.o \
<snip>
include $(TRUNKDIR)/LibCommon.mk
====================================================
and here is LibCommon.mk:
====================================================
# Set include path
CXXFLAGS += $(patsubst %,-I%,$(INCPATH))
# Debug mode
CXXFLAGS_D=$(CXXFLAGS)
CXXFLAGS_D+=-g
# Release mode. Optimise for speed
CXXFLAGS_R=$(CXXFLAGS)
CXXFLAGS_R+=-O3
# Ensure that output directories exist
REQUIRED_DIRS := $(shell mkdir -p $(OBJDIR_D); mkdir -p $(OBJDIR_R) )
# This is the default target.
# Running make with no command line arguments will build the release mode
version of the library.
.PHONY : release
release : $(OBJDIR_R)/lib$(STATICLIBNAME).a
# Running 'make debug' will build the debug mode version of the library.
.PHONY : debug
debug : $(OBJDIR_D)/lib$(STATICLIBNAME).a
# Running 'make all' will build the debug and release mode versions of the
library.
.PHONY : all
all : release debug
# Running 'make clean' will remove the output files
.PHONY: clean
clean:
@rm -rf $(OBJDIR_D)
@rm -rf $(OBJDIR_R)
# Below are the rules for building the debug or release library. Note that
# included in each rule is a command to run versionInfo on the source files
# of the library. versionInfo generates SourceFileInfo.cpp, which is compiled
# and linked into the library and then deleted.
# Rule for building release library
$(OBJDIR_R)/lib$(STATICLIBNAME).a : $(patsubst %,$(OBJDIR_R)/%,$(OBJFILES))
$(TRUNKDIR)/$(SVI) $(CURDIR) KERNEL
$(CXX) -c $(CXXFLAGS_R) SourceFileInfo.cpp -o
$(OBJDIR_R)/SourceFileInfo.o
@rm -f SourceFileInfo.cpp
$(AR) $(ARFLAGS) $@ $^ $(OBJDIR_R)/SourceFileInfo.o

# Include dependency files to ensure they get updated
ifneq "$(MAKECMDGOALS)" "clean"
-include $(patsubst %.o,$(OBJDIR_R)/%.d,$(OBJFILES))
-include $(patsubst %.o,$(OBJDIR_D)/%.d,$(OBJFILES))
endif
# Rule for compiling in release mode

@$(call make-depend,$<,$@,$(patsubst %.o,%.d,$@),$(CXXFLAGS_R))
# Rule for compiling in debug mode

@$(call make-depend,$<,$@,$(patsubst %.o,%.d,$@),$(CXXFLAGS_D))
# $(call make-depend,source-file,object-file,depend-file,cxxflags)
# Compile and create a dependency file
define make-depend
@echo $(CXX) -c $4 $1 -o $2; \
$(CXX) -c -MMD -MP -MF $3.$$$$ $4 $1 -o $2; \
sed 's,\($*\)\.o[ :]*,$(notdir $2) $3 : ,g' < $3.$$$$ > $3; \
rm -f $3.$$$$

Any comments would be appreciated.
