It seems collect simply avoids searching and fully qualifies all .o's.

Few days ago I bought SSD and installed fresh ArchLinux on it. Today I installed these multilib packages:
- binutils-multilib
- gcc-libs-multilib
- gcc-multilib

Also I insalled package fpc and built FreePascal 2.5.1 using this script:
Code: [Select]
export PPCBIN="ppcx64"

if [ -d ./fixes_2_6 ]; then
  svn update ./fixes_2_6
else
  svn co http://svn.freepascal.org/svn/fpc/branches/fixes_2_6 ./fixes_2_6
fi

cd ./fixes_2_6

make FPC=/usr/lib/fpc/2.4.4/$PPCBIN build OS_TARGET=linux CPU_TARGET=i386 CROSSOPT="-XP"
sudo make FPC=`pwd`/compiler/ppcross386 PREFIX=/opt/fpc crossinstall OS_TARGET=linux CPU_TARGET=i386 CROSSOPT="-XP"
sudo make distclean

Then I created symlink for this version. For switching between different versions of FreePascal I use this script(this one switch me to FreePascal 2.5.1):
Code: [Select]
sudo ln -sf /opt/fpc/lib/fpc/2.5.1/ppcx64 /usr/bin/ppcx64
sudo ln -sf /opt/fpc/lib/fpc/2.5.1/ppcross386 /usr/bin/ppc386
sudo ln -sf /opt/fpc/lib/fpc/2.5.1/ppcrossarm /usr/bin/ppcarm
mv ~/fpc.cfg ~/.fpc.cfg

And this one for back to FreePascal 2.4.4:
Code: [Select]
sudo ln -sf /usr/lib/fpc/2.4.4/ppcx64 /usr/bin/ppcx64
sudo ln -sf /usr/lib/fpc/2.4.4/ppcross386 /usr/bin/ppc386
sudo ln -sf /usr/lib/fpc/2.4.4/ppcrossarm /usr/bin/ppcarm
mv ~/.fpc.cfg ~/fpc.cfg

You will be needed only second line and last line. Content of mine fpc.cfg in $HOME directory(also you can add option "-Xd", but I use it separately in Makefile's/etc. of my projects):

I tried to build FreePascal 2.7.1 with my script and found that new version just ignores mine CROSSOPT. So I created symlink /usr/bin/i386-linux-ld to /usr/bin/ld and built it. And everything still works...

I was thinking about installing ArchLinux in a VM to test a bit and noticed that there are three editions. x86, x86_64 and biarch. What versions do you guys use?

(I assume the x86_64 version can be transformed into a biarch by installing packages, but for overview it would still be good to know what you guys started with)

We use separate x86 and x86_64 installations of
Archlinux netinstall.iso

Yes it's the hard way
I can  post (after your request) our steps for installation of
lxde, xfce4, kde, gnome and mate desktops

to Virtual Box or PC
