Hi.

My os is Linux 9. The gcc works well. I have a C program(exe)which can work well on another linux machine. when I run it. The error says:
error while loading shared libraries:libstdc++.so.6: cannot open shared object file: No such file or directory

I looked it up in Internet and did such things:

find|grep libstdc++.so.6
And I find the directory is /lib/ssa
So I export LD_LIBRARY_PATH=/lib/ssa

And when I run the C program. It says:
/lib/ssa/libgcc_s.so.1: version 'GCC_4.0.0' not found /lib/ssa/libstdc++.so.6:version 'GLIBCXX_3.4.4' not found /lib/ssa/libstdc++.so.6:version 'GLIBCXX_3.4.5' not found /lib/ssa/libstdc++.so.6:version 'GLIBCXX_3.4.6' not found /lib/ssa/libstdc++.so.6:version 'GLIBCXX_3.4' not found

I type commands:
ssa># strings libgcc_s.so.1 |grep GCC
GCC_3.0
GCC_3.3
GCC_3.4

And I went to internet to download libgcc1-4.0.1-5mdk.i586.rpm

when I type the command
>strings libgcc1-4.0.1-5mdk.i586.rpm |grep GCC
libgcc_s.so.1(GCC_3.0)
libgcc_s.so.1(GCC_3.3)
libgcc_s.so.1(GCC_3.3.1)
libgcc_s.so.1(GCC_3.4)
libgcc_s.so.1(GCC_3.4.2)
libgcc_s.so.1(GCC_4.0.0)

I also downloaded libstdc++6-4.0.1-5mdk.i586.rpm
>strings libstdc++6-4.0.1-5mdk.i586.rpm|grep GLIBCXX
libstdc++.so.6(GLIBCXX_3.4)
libstdc++.so.6(GLIBCXX_3.4.1)
libstdc++.so.6(GLIBCXX_3.4.2)
libstdc++.so.6(GLIBCXX_3.4.3)
libstdc++.so.6(GLIBCXX_3.4.4)
libstdc++.so.6(GLIBCXX_3.4.5)

But I didn't find GLIBCXX in /lib/ssa/libstdc++.so.6

So I think maybe my libgcc_s.so.1 is too old.

My question is : If I am right, how to update them?

Here is the list of my /lib/ssa

Any hints are highly appreciated.

there is no such thing as "Linux 9" Linux is only on version 2.6 at the moment.... normally people actually mean redhat 9 here, which makes me concerned that you're clearly using rpm's for mandrake (the mdk code in the files you have). assuming it is rh9 then that and gcc4 didn't overlap in lifetime at all, rh9 is pretty old now in the big scheme of things. you might be able to pick up rpm's for it at fedoralegacy.org though.
