Thank you for your reply. My mistake - I meant Realloc (missed the 'e').
This morning I reinstalled MinGW with all the patches suggested by the
Install R on Windows Help page, including w32api-3.7, just to make sure
all was as it should be. I have put
#define WIN32_LEAN_AND_MEAN
at the top of my cpp file (which I did not know about so that was
interesting) but it is still saying there is a conflict between Realloc in
objidl.h and windows.h. Interesting I had a C file which I _did_ manage
to compile with the R.h and windows.h file in without this error coming
up. Could there be something going on with g++ that gcc is ignoring? I
am no sure it iss a clash now as I cannot find Realloc in the R includes
but below is some output I have gathered which may be of assistance.
In objidl.h (line 532):
STDMETHOD_(void*,Realloc)(THIS_ void*,ULONG) PURE;
In R.h it has the solitary line:
/* for PROBLEM ... Calloc, Realloc, Free, Memcpy, F77_xxxx */
Can only find a R_alloc but no Realloc.
