Compiling without -g

Compiling without -g

[Jonathan Buzzard]

Hi,

I grabed a copy of egcs-1.0.1 in order to get a better C++ compiler than
gcc-2.7.2. However without going round editting all the Makefiles is
there anyway to stop it using the -g flag everywhere as I am a little
short on disk space. 

I have tried the --diasble-debug flag but it did not work?


JAB.

CFLAGS=-O2 ./configure  should do it.

	Depending on how you are performing the build, you need to
override BOOT_CFLAGS as well.

The first stage compiler is built with just "-g" for debugging
purposes.

If you want to pass arguments to the first stage build of gcc use
BOOT_CFLAGS=

That is normal, which is how bootstrap works. If you wait until
the build finishes, you will see the latest compiler is compiled
with -O.

I am building egcs on a Linux SMP machine. But I am not using
RedHat 5.0 on it. BTW, if it shouldn't make any difference unless
you use

# make -j 4 MAKE="make -j 4"

ot something like it. In any case, I cannot tell anything wrong.

Either you are not using GNU make, or this is a bug that occurs on your
platform but not mine, or you are assuming behavior based on reading
the makefiles rather than checking it (make variables go in the
environment, so they get passed to recursive makes automatically).

If it is not working the way I described, it is a bug that should be
fixed!  We should not be encouraging people to write perl scripts to
mangle the makefiles.

(note that for 'make bootstrap' there is a different variable BOOT_CFLAGS
that is used by stage 2 and stage 3 builds).

Here's what happens under redhat 5.0.  I configure with CFLAGS=-O and
run "make" with CFLAGS=-O.  As soon as the bootstrap starts in the
gcc/ directory, a -g appears in the compiler arguments and the -O is
gone.

I've noticed.  I am beginning to think it may be because my machine is
SMP.  Has anyone got egcs compiled on a 5.0 machine running SMP?

There are multiple ways of doing that, the two standard ways I know of
doing it is:

1. Tell configure that you want -O2 by setting the CFLAGS environment
   variable before running configure. This will set both CFLAGS and
   CXXFLAGS in the generated Makefile to the specified flags, and these
   will then be passed downwards.

2. Override it when starting make by giving it specific CFLAGS and
   CXXFLAGS (both will probably be necessary here). These will be
   propagated downwards as usual (see 1).


Both these works with egcs AFAIK.

Example of method 1:
setenv CFLAGS -O2   (or export CFLAGS=-O2)
./configure --prefix=whatever ...
make

Example of method 2:
make CFLAGS=-O2 CXXFLAGS=-O2


Do note that both these will generate a compiler without debugging
information, if you run into trouble this can be a problem! 
(If the problem is repeatable it's not that bad)

But at least it's better than this :-)
*All* files? At least check the name against '[Mm]akefile' first.

egcs 1.0.1 compiles fine under RedHat 5.0. Several other people have also
reported that they had no problem compiling egcs 1.0.1 on RedHat 5.0
either.

Not true, at least in some cases I have had to resort to using perl as
shown.  As I recall, the problem was recursive makes that either did
not pass CFLAGS or overrode it.

Warning: you don't want to compile your libraries without -g, or your
users won't be able to debug fully (even if they use -g for their own
code, the lack of -g in the libraries will mean, for instance, that
the debugger things iostreams, strings, etc are unknown classes).

You don't need to edit the makefiles; it suffices to say, for example

make CFLAGS=-O2

Here's what I do sometimes:

find -type f |
	xargs grep -l 'FLAGS[	 ]*=' |
	xargs perl -p -i -e 's#(-O\d?|-g)\b#-O#g if (/FLAGS\s*=/)'

Still haven't been able to get egcs to compile under redhat 5.0,
though...
