[Solved] Libstdc++ Error

[synthesis]

Hi guys

I got this error while launching NTLM multiforce 5.1 (the same about 5.0):

$ ./NTLM-Multiforcer
Launching 64-bit binary
./NTLM-Multiforcer-64: /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by ./NTLM-Multiforcer-64)

This is ldd:

$ ldd NTLM-Multiforcer-64
./NTLM-Multiforcer-64: /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by ./NTLM-Multiforcer-64)

/lib64/ld-linux-x86-64.so.2 (0x00007f9b07715000)

And this is my software configuration:

Linux localhost 2.6.27-gentoo-r8 #4 SMP Thu Jan 22 22:41:10 CET 2009 x86_64 Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz GenuineIntel GNU/Linux

x11-drivers/nvidia-drivers-180.22
dev-util/nvidia-cuda-sdk-2.10.1215.2015
dev-util/nvidia-cuda-toolkit-2.1
sys-devel/gcc-4.1.2

They say it can be a problem concerning GCC, now I try to rebuild my system and if it doesn't work I will upgrade to gcc 4.2 or 4.3

[synthesis]

And finally I did it

Just installed a newer version of gcc:
sys-devel/gcc-4.2.4-r1

And changed profile:

$ gcc-config -l
[1] x86_64-pc-linux-gnu-4.1.2
[2] x86_64-pc-linux-gnu-4.2.4 *

Hope this helps to other people to solve problems like this.
I will post my results in another topic as soon as my tests are complete. Thanks again

Thanks!

I've been doing my development & testing with Ubuntu, haven't touched Gentoo in years.

I had same issue when attempting to load the V0.72 version on Backtrack 4 (currently only has v0.70 in its universe)

Solution:
Download libstdc++.so.6.0.12 (http://ubuntuforums.org/showthread.php?t=1343590)
delete Sym Link (/usr/lib/libstdc++.so.6)
relink to new lib file (ln -s /usr/lib/libstdc++.so.6.0.12 /usr/lib/libstdc++.so.6)
