Coreutils recompilation

Hello everybody, that's my 1st post, I hope I won't do anything wrong.. (sorry for my not british-english language)

My problem:
I have to recompile coreutils on arch linux
- with debug symbols
- without doing any binary stripping
- forcing the use of frame pointer register

besides I've alredy done that for glibc, and fortunately it worked, but the same commands didn't do the same for coreutils

Here what I did with glibc:

Code:

git clone git://sourceware.org/git/glibc.git

cd glibc

git checkout --track -b local_glibc-2.20 master

mkdir build_glibc

cd build_glibc

../glibc-2.20/configure CFLAGS='-g -Og -fno-omit-frame-pointer -ggdb3' --prefix=/usr

make -j 8

make install -j 8

and here what I get:

Code:

file /usr/lib/libc-2.20.so

(ELF 64-bit … dynamically linked … not stripped !)

Code:

readelf --debug-dump /usr/lib/libc-2.20.so | less -Mr

(more or less 3'484'620 rows, brilliant!)

For coreutils:

Code:

wget -c http://ftp.gnu.org/gnu/coreutils/coreutils-8.23.tar.xz

tar -xvJf coreutils-8.23.tar.xz

./configure CFLAGS='-g -Og -fno-omit-frame-pointer -ggdb3'

make -j 8

make install -j 8

but ...

Code:

file /bin/ls

(/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=... ... ..., stripped )
(:banghead:oh no it's stripped and there aren't symbols!)

thank you,

It is probably the makefile doing the stripping automatically,, have a look there first, why do you 'HAVE' to build it with out striping etc, if this is homework then please say so.

Thank you for your answer Keith Hedger,
it's not properly a homework, it' more like a optional exercise in three parts (that one which I posted is just one of them) suggested by my o.s. professor for those who want to go beyond the mere teaching..

saying that are you saying "there is no way avoiding stripping" or I can give to make command arguments to avoid it?

I tried

Code:

make --help

but it wasn't enlighten..

Quote:

Usage: make [options] [target] ...
Options:
-b, -m Ignored for compatibility.
-B, --always-make Unconditionally make all targets.
-C DIRECTORY, --directory=DIRECTORY
Change to DIRECTORY before doing anything.
-d Print lots of debugging information.
--debug[=FLAGS] Print various types of debugging information.
-e, --environment-overrides
Environment variables override makefiles.
--eval=STRING Evaluate STRING as a makefile statement.
-f FILE, --file=FILE, --makefile=FILE
Read FILE as a makefile.
-h, --help Print this message and exit.
-i, --ignore-errors Ignore errors from recipes.
-I DIRECTORY, --include-dir=DIRECTORY
Search DIRECTORY for included makefiles.
-j [N], --jobs[=N] Allow N jobs at once; infinite jobs with no arg.
-k, --keep-going Keep going when some targets can't be made.
-l [N], --load-average[=N], --max-load[=N]
Don't start multiple jobs unless load is below N.
-L, --check-symlink-times Use the latest mtime between symlinks and target.
-n, --just-print, --dry-run, --recon
Don't actually run any recipe; just print them.
-o FILE, --old-file=FILE, --assume-old=FILE
Consider FILE to be very old and don't remake it.
-O[TYPE], --output-sync[=TYPE]
Synchronize output of parallel jobs by TYPE.
-p, --print-data-base Print make's internal database.
-q, --question Run no recipe; exit status says if up to date.
-r, --no-builtin-rules Disable the built-in implicit rules.
-R, --no-builtin-variables Disable the built-in variable settings.
-s, --silent, --quiet Don't echo recipes.
-S, --no-keep-going, --stop
Turns off -k.
-t, --touch Touch targets instead of remaking them.
--trace Print tracing information.
-v, --version Print the version number of make and exit.
-w, --print-directory Print the current directory.
--no-print-directory Turn off -w, even if it was turned on implicitly.
-W FILE, --what-if=FILE, --new-file=FILE, --assume-new=FILE
Consider FILE to be infinitely new.
--warn-undefined-variables Warn when an undefined variable is referenced.

This program built for x86_64-unknown-linux-gnu
Report bugs to <bug-make@gnu.org>

what should I do?

Well to start make --help gives help info for the make program, which is controlled by a makefile which in turn does the actual compiling/installing etc, so in this case 'make --help' doesn't really help, some make files have a 'help' target which can hold useful info wnad would be used like so:

Code:

make help

but this is far from the norm, and is not available in coreutils.

Usually the strip is done separately from the make/install, again not always.

I have had a look at the makefile, it does no stripping, also the commands you give:

Code:

./configure CFLAGS='-g -Og -fno-omit-frame-pointer -ggdb3'

make -j 8

make install DESTDIR=/tmp/xxxx

And they work fine and give this:

Code:

file /tmp/xxxx/usr/local/bin/ls

/tmp/xxxx/usr/local/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, not stripped

So maybe use the DESTDIR=xxx method to make sure you are checking the right file?

thank you very much keith hedger:hattip:, I understood something more about makefiles, and the idea to use "DESTDIR" was great, it worked perfectly at first attempt!!

I think that thread can be closed because, alredy solved.
