RE: gcc compile?

hi, Zack: 

you mean gcc 2.95.3 is supposed to be compiled without the existence of any
previous version of gcc? But for most solaris system, it can't actually,
because the defect in the binded cc compiler to these systems? you mean
actually, we need to "pkgadd" the binary directly in solaris systems? 

i won't install it now, for it has been "pkgadd"ed to my system already. i
am just curious about this problem. 

thanks, 

Regards,
Xu Qiang

All released versions of GCC are intended to be stand-alone, in the
sense you are using (with the unfortunate exception of the Ada front
end).  However, there are a number of problems that can arise, most
common is that the 'inborn cc compiler' doesn't actually work at all
(this is the case on most Solaris systems, for instance).

If you would care to be more specific about what sort of Unix system
you have, and the nature of its bundled compiler, we can be more
helpful.
