Hi you can execute ldd -d -r <name_of_the_executable> to display the dependencies of your application. Maybe the clBLAS library is not visible.

root@user-System-Product-Name:/home/user/clBLAS/src/samples# ldd -d -r example_sgemm.c
not a dynamic executable
root@user-System-Product-Name:/home/user/clBLAS/src/samples# file ./example_sgemm.c
./example_sgemm.c: C source, ASCII text

Is that means my clBLAS install incorrect?

Have you compiled the clBLAS successfully? I thought the issue presented itself during the linking stage with your program.

before I compiled clBLAS, I install AMD ROCm 4.3.1
when compile, it shows some message, then I install some package and set path
1.install gfortran
2.set ROCm dir OpenCL as OpenCL_ROOT
3.install libblas-dev
4.install libboost-all-dev
then clBlas can compiled with no errors.

so I can't figure out why it can't run.

Ok, if you compiled the clBLAS then fine. The next thing you are probably doing is to use the clBLAS in your application. For doing that you have to instruct the compiler where to find the clBLAS headers and libs. it is -I path_to_the_clBLAS_headers and -L path_to_dir_with_clBLAS_libs -lclBLAS
How does it look like in your case?

Hi, after add those command It's seems this problem solved.
thanks.
