Hi,
I have two simple projects in the directory structure given below.
+-home/
|
+-parent/
| |
| +-comp01/
| | |
| | +-Test01.h
| | |
| | +-Test01.cpp
| | |
| | +-main.cpp
| | |
| | +-Makefile
|
+-child/
|
+-comp01/
|
+-Makefile
'child' project needs to build itself using the source from the
'parent' project. This is the Makefile of the 'child' project.
CC = g++
vpath %.cpp .:../../parent/comp01
comp01: main.o Test01.o
$(CC) Test01.o main.o -o comp01
Test01.o: Test01.h Test01.cpp
$(CC) -c Test01.cpp
main.o: main.cpp
$(CC) -c main.cpp
clean:
rm *.o comp01
When I try to build the component 01 (comp01) of the 'child' project,
I get the following error (output given by 'gmake --debug=v')

Can somebody tell me what's wrong here?
My objective is to be able to extend the 'parent' project at the level
of the 'child' by adding some extra source files at the 'child' level.
But, before that I'm trying to just build 'parent' from inside
'child'.
Thanks,
Ishan.
