RE: gcc compile?

[Xu, Qiang (XSSC SGP)]

i found this link:
http://www.linuxfromscratch.org/view/3.3/chapter06/gcc.html 
the article says: 

Dependencies
GCC-2.95.3 needs the following to be installed:


bash: sh
binutils: ar, as, ld, nm, ranlib
diffutils: cmp
fileutils: chmod, cp, ln, ls, mkdir, mv, rm, touch
find: find
gcc: cc, cc1, collect2, cpp0, gcc
grep: egrep, grep
make: make
patch: patch
sed: sed
sh-utils: basename, dirname, echo, expr, hostname, sleep, true, uname
tar: tar
texinfo: install-info, makeinfo
textutils: cat, tail, tr


so it seems to compile gcc2.95.3, the installation of previous version is
necessary, right?

i got a little confused.

Yes, the C compiler is written in C, so you need an existing C compiler to
build it.

This is correct.

Another option is to install (even temporarily) a prebuilt "pkg" for gcc,
such as www.sunfreeware.com.  Be advised that the GCC developers do not
provide support for prebuilt binaries; sunfreeware.com is nevertheless a
reputable site.

This is supposed to be possible, yes.

Yes or no, depending on what you mean by 'the binary'.

If I remember correctly, the package containing the Solaris compiler
that works is called SUNWspro, and you have to pay extra money for it.

The base Solaris system includes a binary named /usr/ucb/cc which just
prints "language optional software package not installed" or words to
that effect, unless SUNWspro is installed.  Even if you do have
SUNWspro installed, you must not use /usr/ucb/cc to build GCC, because
it links against a horrifically broken BSD emulation library.
Building GCC with /opt/SUNWspro/bin/cc, however, does work.

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,

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.

gcc compile?

[Xu, Qiang (XSSC SGP)]

hi, all: 
i have downloaded the full package of gcc 2.95.3, if i want to install it by
the method of "make" and "make install", is any previous gcc version before
2.95.3 is required? 
and which version is the minimal requirement to compile v2.95.3? 

and to compile this previous version, is any version before it is a
requirement? 

if yes, it seems an endless chain. 

is there any stand-alone version of gcc? (stand-alone here means if there is
only the inborn cc compiler with a UNIX system, and this UNIX system hasn't
installed any version of gcc before, can i compile gcc2.95.3 on it?)

i checked the installation notes in the gcc 2.95.3 package, but it didn't
talk of the minimal requirements. 

any idea?

thanks,
