Need some help compiling a C++ code for a R*-tree

Compiler? Version? Example of code? Exact error?

I got that to compile... now I'm having some other problems, linking the files.

Here are the files that I have.

main.cpp ( links to Rjoinr.hpp)
Rjoinr.cpp ( links to Rjoinr.hpp, Heap.hpp, kHeap.hpp, PQMxMxD.hpp)
Heap.cpp (links to Heap.hpp)
kheap.cpp (links to kheap.hpp, Rstart.cpp)
PQMxMxD.cpp (links to PQMxMxD.hpp, Rstart.cpp)
Rstar.cpp (links to Rstar.hpp, lrubuff.hpp)
lrubuff.cpp (links to lrubuff.hpp)

I compiled all the files using g++ -c filename.cpp
now I have al the .o files, but when I try to compile the main.cpp file g++ -o main main.o

I get the following error.
main.cpp: (. text+0x2445): undefined reference to 'RjoinR::statistics()'
....

I also get the same error when I do this g++ -o main main.o RjoinR.o

You can download the files here

g++ Version 4.3.3 Debian 4.3.3-10

Add more points to the question, so I can get some help with the rest of the compilation.

Your sources might be corrupted, but anyways, try gcc -o main main.cpp Rjoinr.cpp Heap.cpp kheap.cpp PQMxMxD.cpp Rstar.cpp lrubuff.cpp

Uh, sorry g++ of course.

Here is the error I'm getting....

This error only occure when I compile the main.cpp with all the others .o files, because the .o files I'm able to create without a problem.

Also all I'm trying to do is read a datafile, and build the index creating the r-tree, and if I have a set of queries I need to calculate the AVG. execution time and the AVG. IO.

Thank you for the comment.. I had the kHeap fixed... but I was compiling the without the two other RjoinR files... :) I guess I'm tired...

Any way... thank you so much.. it worked...
