hi Dirk,
I tried to do the following (I am not sure I understand your
suggestion, since I am a newbie)
- modified the order of -I options in g++. This made no difference.
Probably this was not what you meant.
- I moved
#include <RInside.h>
after all the #include <QSomething> in qtdensity.h
Now the errors are even more, and different from before. A reduced
output obtained by using g++ -E is reported below.
Going back to the original error, g++ complains about Realloc and Free
definitions. This is similar to the problem in this post:
http://stackoverflow.com/questions/11588765/using-rcpp-with-windows-specific-includes
but I don't know how to apply it to my case.
