Unable to include library in make file - c++

Question

I have the following 3 makefiles which have been generated by some other programmer. I have included my code in between which I have marked with a begin and end. The code intends to include the libspatial index library. The other programmer has the hierarchy root directory---->tools--->r
MakeFile1 corresponds to r, MakeFile2 corresponds to tools and MakeFile3 corresponds to root
Now when I include the library I get the error that
make all
make: *** No rule to make target `bin//home/NP/rtree/spatialindex-src-1.8.0/src/storagemanager/DiskStorageManager.cc', needed by `bin/rdf3xload'. Stop.
I am unable to understand as to what mistake did I make. Can someone be kind enough to help me out.

Answer 1

If this is an independent library, it should have its own Makefile and should build alone as well.
If you want to integrate your source into the main build process, you must conform to their structure.
You have
different c++ source suffix .cc vs .cpp
This is easily resolvable by renaming your source files to .cpp.
absolute path /home/NP/rtree/... vs relative path tools/r/...
This would involve moving the entire tree into the main build tree, because the rules expect the directories to be accessible from there.
But I think the best is to have a library Makefile and integrate that into the main build.
Unfortunately, there is no easy answer like change variable X and move line Y. I recommend, sit down with your colleague and resolve this Makefile issue together.
