Installing GCC: Configuration
Like most GNU software, GCC must be configured before it can be built.
This document describes the recommended configuration procedure for both
native and cross targets.

We use srcdir to refer to the toplevel source directory for GCC; we use objdir to refer to the toplevel build/object directory.

First, we highly recommend that GCC be built into a separate directory than the sources which does not reside within the source tree. This is how we generally build GCC; building where srcdir == objdir should still work, but doesn't get extensive testing; building where objdir is a subdirectory of srcdir is unsupported.

Second, when configuring a native system, either "cc" or "gcc" must be in your path or you must set CC in your environment before running configure. Otherwise the configuration scripts may fail.

according to this last paragraph , i don't
understand where to set this c/gcc complier before the gcc-2.95 compiler
is installed  ?
.

# I like this gcc very much , it's strongly introduced by my friends . I extremly hope to get your help to install it on my sparc .

and  here is the log file when i first configure
