Error When Building C++

[joinkumaresh]

Hi

(I' am using: c++,Eclipse,CDT,Mingw & GDB on windows xp)

When i have my header files in 'scorce folder' then it's working fine..

but if i have my header files in separate 'header folder' then comes the error..

'function1' was not declared in this scope
function1.h: No such file or directory

I tried with these 2 makefile files but it seem to be not working, please see if someone can help me in this.


1)
main.exe: main.o function1.o
g++ main.o function1.o -o main.exe
main.o: main.cpp function1.h
g++ -c main.cpp
function1.o: function1.cpp function1.h
g++ -c -I"C:\Documents and Settings\kdevarajan\workspace\Mycpp\Header" function1.cpp

2)
main.exe: main.o function1.o
g++ main.o function1.o -o $@
.cpp.o: function1.h
g++ -c -I"C:\Documents and Settings\kdevarajan\workspace\Mycpp\Header" $< -o $@

Thanks in advance...

I use the same configuration (c++, Eclipse, etc.), except that Eclipse manages the makefile for me :). But if I remember correctly, you need to specify the path to the header file when you include it.
E.g. if the file you want to include function1.h into is in the folder "source" and "Header" is a subfolder of "source", then you need to type #include "Header/function1.h".
Or if the folder "source" and "Header" are in the same folder (siblings), then write #include "../Header/function1.h".
I use this in my projects and works fine.

Bye,
