Problem in compile

Hi all,
i have a problem on compile,i have Linux ubuntu 64bit ver10.04 and ati 4850 1gb

I have installed ati-stram-sdk last version ati-stream-sdk-v2.3-lnx64

I have added in my bash-hrc:
export ATISTREAMSDKROOT=/home/davide/ati-stream-sdk-v2.3-lnx64
export ATISTREAMSDKSAMPLESROOT=/home/davide/ati-stream-sdk-v2.3-lnx64
export LD_LIBRARY_PATH=$ATISTREAMSDKROOT/lib/x86_64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$ATISTREAMSDKROOT/lib/x86:$ATISTREAMSDKROOT/lib/x86_64:$LD_LIBRARY_PATH

registration icd with icd-registration.tgz all from ati site
and
Ati sapmles works right foir example CLInfo:

But when i try to use makefile for compile my work:

Linking:( Main.o Solver.o )
/usr/bin/ld: cannot find -lOpenCL
collect2: ld returned 1 exit status

my makefile:
CFLAGS = -I$(MTL) -Wall -ffloat-store -I$ATISTREAMSDKROOT/include
LFLAGS = -lz -lOpenCL -L$ATISTREAMSDKROOT/lib/x86_64

i suppose my problems are on library but can’t find fix any suggestion or need another information or i make something wrong?

Why don’t you have a look at the compilation flags used for CLInfo, since you know that this one app builds fine?

Yes i have look but i doesn’t realy understand what i really need in it…
Its ATI SDK samples the make includes two file in atistreamsdk/make/ there is one file for compiling rules and one for dependecies but i don’t know where are the rights compilation flags used for CLInfo…if u need i can post it here…

Hi Dave88,

Has your problem been resolved? Maybe you want to post your compliation flags here so that we can take a look to see if we can resolve your issue.

Thanks.
