error while loading shared libraries: libXXX.so.x: cannot open shared object file: No such file or directory .　

此时你可以locate libXXX.so.x 一下,查看系统里是否有该文件，大部分情况是该文件存在。然后把libXXX.so.3所在的目录加入到 /etc/ld.so.conf 中。
如果发现libXXX.so.x不存在，你可能没安装包含库的程序。一般google一下“XXX linux”就能找到相应的软件.

如，我执行一个fedora10 的内核编译配置时，输入make xconfig，出现以下提示：error while loading shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or directory .
 

[peng@localhost /]$ locate libqt-mt.so.3
/usr/lib/qt-3.3/lib/libqt-mt.so.3
/usr/lib/qt-3.3/lib/libqt-mt.so.3.3
/usr/lib/qt-3.3/lib/libqt-mt.so.3.3.8
[peng@localhost ~]$ cd /etc
[peng@localhost etc]$ sudo gedit ld.so.conf   （添加 /usr/lib/qt-3.3/lib）
[peng@localhost etc]$ sudo ldconfig

Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
