"error while loading shared libraries: libmkl_intel_lp64.so.1: cannot open shared object file"
- Optimization Solution:
- Before calling the
qbics-linux-cpuexecutable, source the intel_oneapi'ssetvars.shfile again. - Directly add source
<path>/setvars.shto the environment variables (recommended, but some servers may encounter issues with file transfers after adding to the environment variables, so use with caution).
Locate and replace the path of intel_oneapi.
In different servers, the location of the Intel compiler varies. Users need to find the absolute path where the Intel compiler is installed.
- Optimization Solution:
- Confirm whether the Intel compiler is installed by using the which icc command. If installed, skip directly to Step 3.
-
Enter the command
module availto search for the Intel module, and executemodule load <intel module>to load it, then save it to the environment variables. -
Save the path of the Intel compiler to
/lustre/software/intel_oneapi(note that the path obtained afterwhich iccis not the direct path we use; we need to find the path containing thesetvars.shfile based on this path). -
Replace the path of the Intel compiler in the
build.shfile AND the~/qbics-src/Makefile-linux-cpufile.
setvars.sh has already been executed and does not need to be run again.
WARNING: setvars.sh has already been run. Skipping re-execution.
- Optimization Solution:
If you wish to re-execute the source ~/setvars.sh script, you can add the --force keyword
after the source <path>/setvars.sh in the build.sh file to override this behavior.
An error message appears when compiling Qbics.
No rule to make target '/opt/intel/oneapi/mkl/2021.4.0/include/mkl.h', needed by 'build/linux-cpu/obj/basis/BasisSetData.o'
- Optimization Solution:
Execute the command make -f Makefile-linux-cpu directly in the qbics-src folder instead of compiling Qbics through the build.sh script.
