[ILUG] C++ woes...

[Dave Airlie]

Okie on skynet, I have a c++ program that compiles very simple program,
just iostream.h and cout and a class,

I have rpms
egcs-c++-1.1.2-12
libstdc++-2.9.0-12
glibc-2.1.1-6
egcs-1.1.2-12

and in /usr/lib I have

-rw-r--r--   1 root     wheel     2036516 Mar 21  1999
/usr/lib/libstdc++-2-libc6.1-1-2.9.0.a
-r-xr-xr-x   1 root     wheel     1184870 Mar 21  1999
/usr/lib/libstdc++-2-libc6.1-1-2.9.0.so
lrwxrwxrwx   1 root     wheel          29 Sep 23 16:25
/usr/lib/libstdc++-libc6.1-1.a.2 -> libstdc++-2-libc6.1-1-2.9.0.a
lrwxrwxrwx   1 root     wheel          30 Sep 23 16:26
/usr/lib/libstdc++-libc6.1-1.so.2 -> libstdc++-2-libc6.1-1-2.9.0.so
lrwxrwxrwx   1 root     wheel          20 Sep 23 16:38
/usr/lib/libstdc++.so.2.7.2 -> libstdc++.so.2.7.2.8
-rwxr-xr-x   1 root     wheel     1025339 Mar 21  1999
/usr/lib/libstdc++.so.2.7.2.8
lrwxrwxrwx   1 root     wheel          18 Sep 23 16:38
/usr/lib/libstdc++.so.2.8 -> libstdc++.so.2.8.0
-rwxr-xr-x   1 root     wheel      375773 Mar 21  1999
/usr/lib/libstdc++.so.2.8.0

It all works fine for me on an RH6.0 just installed box ..
