Package: g++-4.1
Version: 4.1.1-13
Severity: minor

Hello,

Apropos the recent posting by Christian Aichinger and his checklib
scripts with output at http://rerun.lefant.net/checklib.

Some of these problems (at least in the case of swish++) are caused
by the fact that when "g++" is used in the link phase of the
compilation it adds "-lm -lgcc_s" and so on to the call to
"collect2".

This means that libraries whose symbols are not to be found in the
binary are still listed as NEEDED in it. This creates additional
dependecies etc.

This appears to be a known and "wontfix" problem with g++. See for
example this thread:

        http://gcc.gnu.org/ml/gcc/2005-01/msg00229.html

For now the only solution seems to be to *not* use "g++" to perform
the linking and instead use "gcc" with the additional "-lstdc++"
command line argument. The "-Wl,--as-needed" switch may also work.

Regards,

Kapil.

thanks

closing this as won't fix. Another alternative would be to use g++
-nostdlib or -nodefaultlibs.
