Dear R-devel,
My g++ complains about the first argument to Rprintf being non-const char *.
For example when compiling the line
Rprintf("hello world\n");
the following warning is emitted:
warning: deprecated conversion from string constant to 'char*'
Is there a reason for the non-const? It is curious that Rf_error, which is
similar to RPrintf, is const.
If there is a need to keep it non-const in C please consider using the patch
below in future releases.
Thanks,
Vadim
Patch to R-2.6.1/include/R_ext/Print.h
#ifdef __cplusplus
extern "C" {
#define CONST const
#endif
void Rprintf(CONST char *, ...);
void REprintf(CONST char *, ...);
void Rvprintf(const char *, va_list);
void REvprintf(const char *, va_list);
#ifdef __cplusplus
}
#undef CONST
#endif
