{ZW} This happens when you have installed glibc as the primary C library but
|
||||
have stray symbolic links pointing at your old C library. If the first
|
||||
`libc.so' the linker finds is libc 5, it will use that. Your program
|
||||
expects to be linked with glibc, so the link fails.
|
||||
|
||||
The most common case is that glibc put its `libc.so' in /usr/lib, but there
|
||||
was a `libc.so' from libc 5 in /lib, which gets searched first. To fix the
|
||||
problem, just delete /lib/libc.so. You may also need to delete other
|
||||
symbolic links in /lib, such as /lib/libm.so if it points to libm.so.5.
