Hello,

while trying to compile kdemultimedia-arts-3.5.2 with gcc-4.1.0 and --as-needed, I come across this error :
Code:
/bin/sh ../../libtool --silent --mode=link --tag=CXX i686-pc-linux-gnu-g++  -Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align -Wconversion -Wchar-subscripts -Wall -W -Wpointer-arith -DNDEBUG -DNO_DEBUG -O2 -pipe -Os -march=pentium-m -ftracer -fweb -fomit-frame-pointer -fvisibility-inlines-hidden -Wformat-security -Wmissing-format-attribute -Wno-non-virtual-dtor -fno-exceptions -fno-check-new -fno-common -DQT_CLEAN_NAMESPACE -DQT_NO_ASCII_CAST -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION   -Wl,-O1 -Wl,--as-needed -Wl,--sort-common -o artsbuilder -L/usr/kde/3.5/lib -L/usr/qt/3/lib -L/usr/lib -Wl,--as-needed -Wl,--enable-new-dtags  -R /usr/kde/3.5/lib -R /usr/kde/3.5/lib -R /usr/qt/3/lib -R /usr/lib artsbuilder.all_cpp.o  -lkio -lqtmcop -lX11  -lpthread ../../arts/runtime/libartsbuilder.la -lsoundserver_idl -lartskde

Basically it can't find std::string, probably because of --as-needed, so I change the command, adding -lstdc++ :

And it works. However, I would like to automate this, and provide patch that could be useful to everyone. I couldn't find where this command comes from - I have very limited knowledge of the autotools. Could someone point me in the right direction ?

Thanks !

media-gfx/autotrace compiles but fails when executing (cannot find acos function when compiling lilypond).

I've set in make.conf:
Code:
LDFLAGS="-Wl,-O1 -Wl,--sort-common --enable-new_ldflags"


Then I tried to emerge some small packages and got the following error during ./configure:
Code:
checking for i686-pc-linux-gnu-gcc... (cached) gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.



UPD: Excluding --enable-new_ldflags fixes the problem

The proper format would be:

Code:
LDFLAGS="-Wl,-O1 -Wl,--sort-common -Wl,--enable-new_ldflags"


I don't really see any use for you to use --enable-new_ldflags, because if you are running ~x86, then --as-needed shouldn't give you but one or two fails.

Sorry, I don't understand you...

Shall I have failed emerges with my LDFLAGS? But it's written in a first post that --enable-new_ldflags will not enable --as-needed for packages which doesn't support it?

He means almost every package on ~x86 should work with --as-needed, and afaik there's only a few packages that accept --enable-new_ldflags.

--enable-new-ldlflags is a KDE configure option. It's nothing you should put in your LDFLAGS and it doesn't work for anything but KDE packages.

Ah, thanks for replies. I didn't know that from first post...

Since the last post is from mid 2006, any update on the work in progress here?
I guess I'll just attain to -Wl -O1

The only update I can give you is to look in the bugzilla and at the gentoo-dev mailinglist. Flameeyes and a couple of other people has been pushing makeing as-needed into the default compile-rules. Go search the bugzilla for more info.

A quick look at /usr/portage/profiles/default/linux/make.defaults gives:
Code:
# 2008/07/09 - Doug Goldstein <cardoe@gentoo.org>
# Adding LDFLAGS="-Wl,-O1 for all Linux profiles by default
# after discussion on the gentoo-dev ML. As we bang out a clear
# direction with how LDFLAGS will be set by default, this entry
# may move.
LDFLAGS="-Wl,-O1"

Also binutils are compiled with --hash-style=both by default, so adding --hash-style=gnu is perfectly safe.

--as-needed works for most ebuilds in portage too.

The emul-linux-x86 binary packages are compiled with those 3 flags set.

Thanks for the update, guys..
Yeah, good for them to be doing this since even if there's no noticeable or no speed upgrade at all, keeping dependecies that are not actually needed away from software seems like a good motion to keep things ordered
