    <p>I have some C++ classes, every one into his own folder with a makefile, test.cpp for testing purpose, etc.</p> <pre><code>Main folder |-&gt; Class1 folder |-&gt; Class2 folder |-&gt; Class2.1 folder |-&gt; Class2 folder </code></pre> <p>I have a main project, that must include these classes. I am trying to include all sub-makefiles into the main makefile.</p> <p>I have tryed with "INCLUDE POO/makefile", but this solution has 2 problems:</p> <ul> <li>The path of the sub-makefiles is incorrect, so files are not found ("There is not rule to build the target 'Vector3D.cpp'").</li> <li>The "test.cpp" file is overrided, probably because of the path problem.("warning: overriding recipe for target ...")</li> </ul> <p>I would like all makefile independent, so I may copy/past the class folder into a new project and it still working, or I may exec the makefile alone without changes on it.</p> <p>So the question is: How to include (correctly) a makefile into an other makefile?</p> <p><strong>Example, just for test purpose.</strong></p> <p>Main makefile (simplified)</p> <pre><code>include Vector3D/makefile include Color/makefile CPP = g++ CXXFLAGS = $(CXXINCS) -Wall -O0 all: main main: main.o Vector3D.o Color.o $(CPP) main.o Vector3D.o Color.o -o main main.o: main.cpp $(CPP) -c main.cpp -o main.o $(CXXFLAGS) </code></pre> <p>Sub-makefile example (simplified)</p> <pre><code>#Vector3D CPP = g++ CXXFLAGS = $(CXXINCS) -Wall -O0 all: test test: Vector3D.o test.o $(CPP) Vector3D.o test.o -o test Vector3D/test.o: test.cpp $(CPP) -c test.cpp -o test.o $(CXXFLAGS) Vector3D.o: Vector3D.cpp Vector3D.hpp $(CPP) -c Vector3D.cpp -o Vector3D.o $(CXXFLAGS) </code></pre> <p>Similar for Color/makefile than Vector3D</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
