我在CentOS 6计算机上编译的一个软件给我一个错误，我在Ubuntu 14.10笔记本电脑上编译完全相同的软件没有看到错误：
auxgen: error while loading shared libraries: libquadmath.so.0: cannot open shared object file: No such file or directory
有问题的图书馆似乎确实存在于CentOS机器上：
$ locate libquadmath
/usr/local/lib/libquadmath.a
/usr/local/lib/libquadmath.la
/usr/local/lib/libquadmath.so
/usr/local/lib/libquadmath.so.0
/usr/local/lib/libquadmath.so.0.0.0
/usr/local/lib64/libquadmath.a
/usr/local/lib64/libquadmath.la
/usr/local/lib64/libquadmath.so
/usr/local/lib64/libquadmath.so.0
/usr/local/lib64/libquadmath.so.0.0.0
/usr/local/share/info/libquadmath.info
$ ldd /usr/local/bin/auxgen
/usr/local/bin/auxgen: /usr/lib64/libgfortran.so.3: version `GFORTRAN_1.4' not found (required by /usr/local/bin/auxgen)

/lib64/ld-linux-x86-64.so.2 (0x000000330c000000)
在我的Ubuntu 14.10笔记本电脑上，它的工作原理：
$ ldd /usr/local/bin/auxgen
linux-vdso.so.1 => (0x00007fff7aaf2000)
libgfortran.so.3 => /usr/lib/x86_64-linux-gnu/libgfortran.so.3 (0x00007fd71b5da000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fd71b215000)
libquadmath.so.0 => /usr/lib/x86_64-linux-gnu/libquadmath.so.0 (0x00007fd71afd6000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fd71acd0000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fd71aab9000)
/lib64/ld-linux-x86-64.so.2 (0x00007fd71b922000)
在Ubuntu笔记本电脑上工作：
$ ldconfig -p | grep 'quad\|gfort'
libquadmath.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libquadmath.so.0
libgfortran.so.3 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgfortran.so.3
在不起作用的CentOS上：
$ ldconfig -p | grep 'quad\|gfort'
libgfortran.so.3 (libc6,x86-64) => /usr/lib64/libgfortran.so.3
libgfortran.so.3 (libc6) => /usr/lib/libgfortran.so.3
有什么想法吗？
