I found I can't install many softwares because the version of libstdc++.so in FC4 is 6 while in legacy FC is libstdc++.so.5
Many software installation program can't fine libstdc++.so.5 and then they abort the installation.

How can I solve the problem?

thanks

What programs, for example, are you trying to install? Can you list some?

Do you have all the compat libraries installed?
http://www.mjmwired.net/resources/mj...c4.html#compat

[mirandam@charon ~]$ rpm -q --whatprovides libstdc++.so.5
compat-libstdc++-33-3.2.3-47.fc4
[mirandam@charon ~]$ rpm -q --whatprovides libstdc++.so.6
libstdc++-4.0.0-8

You need to install the libstdc++.so.5 library.

Enter the command as root:
# yum install libstdc++.so.5

ok

Did it work for you?

yes
it works now
thank you very much

Trying to load Thunderbird in Fedora 4, and having the same issue:

[root@localhost thunderbird]# ./thunderbird
./thunderbird-bin: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
[root@localhost thunderbird]#

Tried the above solution, but it did not work for me. Had to switch users and get email to activate after registering here, so ran it again to copy resulting error message:

[root@localhost jmehl]# yum install libstdc++.so5

Any suggestions?

Edited: Istalled compat-libstdc++-33 and compat-libstdc++-296 and ran it again...it works now.

you missed a dot
yum install libstdc++.so.5
rather tan yum install libstdc++.so5

I'm having problems with installing libstdc++.so.5 via yum. Is there any other way around for this???

What kind of problems? Also, as said before, it's in the "compat-libstdc++-33" package, so you can install that manually.

I was having the same problem: fc4 don't come with libstdc++.so.5, sybase express edit. v.15.0 need it; thank for the notes here, are very helpful.

Regards,

download compat-libstdc++-33-3.2.3-47.fc4.i386.rpm from here:

http://rpm.pbone.net/index.php3/stat....i386.rpm.html

install it:
#rpm -ivh compat-libstdc++-33-3.2.3-47.fc4.i386.rpm

run command:
#yum install libstdc++.so.5

This works to me, thanks.

For users running Fedora 8, I think it is easier to just double click on the rpm package with the appropriate compat file (compat-libstdc++-33-3.2.3-62.i386.rpm appropriate for Fedora 8 with 32 bit installation).
