想请教一下：我费了一个周末的时间才装好device driver\_3.2\_linux\_32\_260.19.26.run,cudatoolkit\_3.2.16\_linux\_32\_ubuntu10.4.run,gpucomputingsdk\_3.2.16\_linux.run.现在我想试试我的平台是否安装成功，我的cuda的位置：/sur/local/cuda，我的gpucomputingsdk在：/root/NVIDIA\_GPU\_COMPUTING\_SDK。当我编译deviceQuery成功后生成：deviceQuery.cpp.o，但是当我执行的时候：$ ./deviceQuery,出现如下错误提示：./deviceQuery: error while loading shared libraries: libcudart.so.3: cannot open shared object file: No such file or directory。后来我看了一下，其实libcudart.so.3是在/usr/local/cuda/lib当中，为什么会找不到呢？不明白，请高手指点一下，谢谢。

查/etc/ld.so.conf

åŠ /usr/local/cuda/lib

æˆ–è€…å¦‚æžœä½ æœ‰/etc/ldso.conf.d/ç›®å½•ï¼Œæ–°å»ºä¸€ä¸ªæ–‡ä»¶åŠ /usr/local/cuda/lib

åŠ å®ŒåŽè·‘ldconfig

请用英文，那么帮助来得快些

did you add

"

export PATH=$PATH:/usr/local/cuda/bin

export LD\_LIBRARY\_PATH=$LD\_LIBRARY\_PATH:/usr/local/cuda/lib

"

to the ~/.bashrc or the ~/.bash\_profile ?
