error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory


I know where that libstdc++.so.5 is so I export LD_LIBRARY_PATh=/path to libstdc++.so.5,

but I still getting the same error.

Why? I know getting the LD_LIBRARY_PATH right to include that library should do it.

libstdc++.so.5 ????

that is old ,very old .


it is part of the compatibility gcc3.3 ( or 3.4 ) tools

and would be installed to the system default /usr/lib , or /usr/lib64

and THAT is in the system $PATH and $LD_LIBRARY_PATH by default



What operating system and What program is trying to use a very old version of libstc

I am using Ubuntu 14.04 LTS. The OS should able to locate that libstdc++.so.5 right? I am running an open source development program, not a well known one. Why can't the OS locate it?

double check that there is inded a file
/usr/lib64/libstdc++.so.5

but if you need that old of a version
you should be using older gcc3.3 or 3.4 to build the program
and NOT the default version 4

you can have many different versions off gcc installed
right now i have
gcc-3.3
gcc 4.1
gcc 4.8

i am not using gcc5 right now

libcstdc++ in not in my /usr/lib64 or /usr/x32 folder. That's why I manually pointed by export LD_LIBRARAY_PATH.
its prebuilt binary, I do not have the source. Can't change GCC.

well if you do not have that library installed
then HOW can you point gcc to it ?

it is part of the gcc3.3 compatibility deb

install the old compatibility gcc 3.3
and use that to build the old code that needs the old stdc 5

why not ?

or set alternatives
or
explicitly call 3.3

These are the default gcc`s included with Ubuntu 14.04 :
gcc-4.4/g++-4.4, gcc-4.6/g++-4.6, gcc-4.7/g++-4.7, gcc-4.8/g++-4.8 ,,,
where "4.8" is the system compiler.

Switching compiler : $ export CC=gcc-4.4 CXX=g++4.4 && <other command>


But : You don't need any gcc packages to get libstdc++.so.5 :
http://packages.ubuntu.com/trusty/libstdc++5
.... Just install the package (may not be present in "the funny Package Manager") :
$ sudo apt-get install libstdc++5

Or install synaptic : $ sudo apt-get install synaptic
... to get a 'Package Manager' that has all available packages visible.
