Question

我在运行需要它们的脚本时遇到加载共享库的问题：

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

但是，我认为我的设置没问题：

set LD_LIBRARY_PATH = /lfs/data0/g_local/intel/composer_xe_2011_sp1.7.256/compiler/lib/intel64
export LD_LIBRARY_PATH

和ls /lfs/data0/g_local/intel/composer_xe_2011_sp1.7.256/compiler/lib/intel64表明libirc.so确实存在。

echo $LD_LIBRARY_PATH正确返回：

/lfs/data0/g_local/intel/composer_xe_2011_sp1.7.256/compiler/lib/intel64

它仍然无效，所以我有点绝望...... :)

有人可以帮我吗？

一些有用的信息：

echo ${SHELL}
/bin/bash

另外，我运行的脚本在开头包含了这个：

#!/bin/csh
#PBS -z
#PBS -S /bin/csh

set PATH = /usr/local/x86_64/gnu/openmpi-1.4.5/bin
export PATH

谢谢！

Answer 1

听起来你在群集上运行它，在这种情况下，问题与你的shell无关。试试：

#PBS -v LD_LIBRARY_PATH="/lfs/data0/g_local/intel/composer_xe_2011_sp1.7.256/compiler/lib/intel64"

值得注意的是

set LD_LIBRARY_PATH = /lfs/data0/g_local/intel/composer_xe_2011_sp1.7.256/compiler/lib/intel64

是csh语法，而你说你正在运行bash。 bash等价物是

LD_LIBRARY_PATH=/lfs/data0/g_local/intel/composer_xe_2011_sp1.7.256/compiler/lib/intel64

它的间距敏感。

感谢nneonneo，这是它给出的内容:(我只是粘贴消息的开头，因为它很长，让我知道是否需要完整的输出）：
