Dear Rooter's


I just sucessfully made root for sun 5.6 with egcs1.1.1. I used Makesolarisegcs.mk found in the $ROOTSYS/src dir and I followed  Jonathan Hays' outline (roottalk 16 Dec 1998) which describes the code modifications.  This worked well until the make of root.exe which failed due to missing sincos in the linking. Adding -lsunmath also failed because the linker could not find it( and I could not either).


I found a fix by modifying  BASE_Math.cxx(line 46)
from:
#if (defined(sun) && !defined(R__I386) && !defined(__SunOS_5_6)) || \
    (defined(__OPTIMIZE__) && \
     (__GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ > 7)))
   extern "C" void sincos(Double_t, Double_t*, Double_t*);
#else
to:
#if (!defined(sun) && !defined(R__I386) && !defined(__SunOS_5_6)) || \
    (defined(__OPTIMIZE__) && \
     (__GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ > 7)))
   extern "C" void sincos(Double_t, Double_t*, Double_t*);
#else

I know this just a kludge, but it works. 



Thanks to everyone who helped...
