Hi, I think the ansi non-compliant part of TMath.h is that there are missing prototypes for functions __finite and __isnan. (glibc-2.2.5, gcc-3.0, Debian/Linux/PPC) #if defined(R__GNU) && defined(__STRICT_ANSI__) # define finite __finite # define isnan __isnan #endif and inline Int_t TMath::Finite(Double_t x) #ifdef R__HPUX11 { return isfinite(x); } #else { return finite(x); } #endif of TMath.h transform to inline Int_t TMath::Finite(Double_t x) { return __finite(x); } Adding prototypes for them should fix the problem (perhaps for isfinite which is described by ISO C99). cheers -- Jiri
