Jeff,

Below is part of my make file
CPP  = g++.exe
CC   = gcc.exe
WINDRES = windres.exe
RES  = 
OBJ  = main.o $(RES)
LINKOBJ  = main.o $(RES)
LIBS =  -L"D:/Dev-Cpp499/lib" -L"D:/boost/lib"
-L"D:/boost/lib/libboost_date_time-gcc-1_31.a"  
INCS =  -I"D:/Dev-Cpp499/include" 
CXXINCS =  -I"D:/Dev-Cpp499/include/c++/3.3.1" 
-I"D:/Dev-Cpp499/include/c++/3.3.1/mingw32" 
-I"D:/Dev-Cpp499/include/c++/3.3.1/backward" 
-I"D:/Dev-Cpp499/lib/gcc-lib/mingw32/3.3.1/include" 
-I"D:/Dev-Cpp499/include" 
-I"D:/boost/include/boost-1_31" 
BIN  = newtest.exe
CXXFLAGS = $(CXXINCS)  
CFLAGS = $(INCS)  

all: all-before newtest.exe all-after

clean: clean-custom
        rm -f $(OBJ) $(BIN)

$(BIN): $(OBJ)
        $(CPP) $(LINKOBJ) -o "newtest.exe" $(LIBS)

main.o: main.cpp
        $(CPP) -c main.cpp -o main.o $(CXXFLAGS)

I did include the libboost_date_time-gcc-1_31 but it
did not work.

Can you spot something I am not doing correctly? 
Thanks for the help.

George
