Which version of GCC to use: an example

Which version of GCC to use: an example

[Bob Gustafson]

My goal was to compile and install prcs-1.3.1  (a new source code
control system)

I started out with gcc version 2.96 which is the stock version supplied
with RedHat 7.2 (for i686-pc-linux-gnu)

   ./configure 2>&1 | tee config.out
    make 2>&1 | tee make.out

The last few lines of make.out are:

    make[3]: Entering directory `/usr/local/src/prcs-1.3.1/src'
      c++ -DHAVE_CONFIG_H -I. -I. -I.. -I./include -O2 -Wall

.....
I thought it might be a problem with the compiler, so I downloaded and
installed gcc-3.0.3 and reconfigured and compiled prcs
(files expanded fresh from tar.gz).

It still won't make. Last bit of the make.out file is given  below
( make 2>&1 | tee make.out).

Finally, I installed gcc version 2.95.3  (2.95.3 20010315 (release)) and
this worked fine.

I don't know if there are bugs in the compiler(s) or bugs in prcs-1.3.1,
but this might be a regression test to pass for the newer compilers.

There never was a 2.96 release of GCC. This branch was only for 
development. If RedHead ships broken compilers with it's release,
RedHead users have to live with this -- haven't they ;-) ?

Me too took gcc-3.0.3 last week, to set it up as a secondary compiler
but I don't have much luck with it. To say the thruth - I havent much
time just now for such an experiment.

I've already built whole systems with this version. If you have
glibc-2.2.x you'll need the gcc-2.95.3-2.patch.

The task for you to find out.

on an RH7.2 system the following often fixes compiler issues;

As Frank Schafer already pointed out, you should never use gcc 2.96
because there never was such a release.

prcs is not complying with the ANSI C++ Standard as required by gcc
v3. prcs needs to be fixed until you're able to compile it with gcc
v3.

I just used what came with RH 7.2  (However, I am now using 2.95.3)

From the listing of make errors, do you have any guidance as to what part
of the ANSI C++ Standard is being violated?

Also, if 2.95.3 does the job, why doesn't 3.0.3 flag (and deprecate) the
things that pass 2.95.3 and do not pass 3.0.3  :-)

Okay, but I never understood why RedHat shipped its distribution with
that compiler, nor did I understand why the GCC people called their
development version "2.96".

At first, stdiostream.h apparently was removed from the stdc++ lib
distributed with gcc v3. Thus, there is no class `stdiobuf' (I
couldn't find it in "The C++ Standard Library" book nor in any of the
header files of gcc's standard c++ library).

The other errors seem to result due gcc getting confused -- it seems
gcc doesn't recognize the `const' keyword anymore... E.g. in
include/prcserror.h:509: parse error before `char' :

omanip<const char*> query(const char* message);

I suppose that would blow up the compiler quite a bit. Eventually, you
would need to distribute a complete gcc v2.95 with it in order to say
"hey, it would compile with gcc v2.95.x but not with the release of
gcc you're using now." It's a lot easier to say: "just write standard
compliant code!".

I had heard of some controversy about RH's choice of compilers, but now
have switched to 2.95.3

Looking in the build directory for gcc, I see a ./install/glibc-2.2.patch -
I assume that it was applied (??) during the gcc build process (??).

How do I tell for sure? (gcc-2.95.3 was built from source files on this
machine)

It looks like I do have the glibc-2.2.4 (see below)

Nothing too much, but I like to try something new from time to time. I have
CVS, but don't use it enough for my own stuff. Perhaps PCRS will fit in
more naturally. Or, maybe I can just script it to do what needs to be done
automatically.  I only need it for backup and to keep my toes from being
shot off.
