I have written a little C++ program, which uses a third party library called ANN (approximate nearest neighbours)....
#include "/home/sekemp/ann_0.2/include/ANN/ANN.h"
I have tried R CMD SHLIB ann.h myProgram.cc, although this compiles when I load it into R I get the following message..
dyn.load("/home/sekemp/ann_0.2/ann.so")
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library "/home/sekemp/ann_0.2/GammaTest.so":
/home/sekemp/ann_0.2/GammaTest.so: undefined symbol: _ZN10ANNkd_treeC1EPPdiii12ANNsplitRule
I get the same error when I dyn.load the myProgram.so aswell.
There is nothing wrong with the ann library as I have used it directly in C++ using the compiler-linker thingy....
g++ myProgram.cc -I/home/sekemp/ann_0.2/include -L/home/sekemp/ann_0.2/lib -lANN
Does anyone have any ideas?
Cheers,
Sam.
