OpenCL问题

Question

I have a problem in compiling simple program using openCL under Ubuntu. I have downloaded the AMD stream SDK from the AMD site and I have installed it using the installation notes from the same site. I have copied a simple hello world program from a OpenCL manual and I've tried to compile it using the command suggested from manual :

gcc -o hello -I '$AMDSTREAMSDKROOT/include' -L '$AMDSTREAMSDKROOT/lib/x86_64' hello.c ‐lOpenCL    

but the answer from the compiler is

gcc: error: ‐lOpenCL: no such file or directory

Does anyone has any ideas about this problem? Thanks

You appear to be using strong quotes (single quotes), which will prevent the environment variable $AMDSTREAMSDKROOT from being expanded. Try using double-quotes instead:

gcc -o hello -I "$AMDSTREAMSDKROOT/include" -L "$AMDSTREAMSDKROOT/lib/x86_64" hello.c ‐lOpenCL
