./filezilla:/usr/lib/libstdc++.so.6:version ' glibcxx_3.4.15 ' not found (required by./filezilla)

If the 64-bit system error message is as follows:

./filezilla:/usr/lib64/libstdc++.so.6:version ' glibcxx_3.4.15 ' not found (required by./filezilla)

The reason is that there is no glibcxx_3.4.15 version, or a higher version.
Enter the command to query the results:

[Root@localhost ~]# strings/usr/lib/libstdc++.so.6 | grep glibcxx
glibcxx_3.4
glibcxx_3.4.1
glibcxx_3.4.2
glibcxx_3.4.3
glibcxx_3.4.4
glibcxx_3.4.5
glibcxx_3.4.6
glibcxx_3.4.7
glibcxx_3.4.8
glibcxx_3.4.9
glibcxx_3.4.10
glibcxx_3.4.11
glibcxx_3.4.12
glibcxx_3.4.13
Glibcxx_force_new
Glibcxx_debug_message_length

We see that there is really no glibcxx_3.4.15 in the current GCC version.

The 64-bit system commands are:
