 In the directory where you unpacked OpenBLAS, create a build directory for cmake, and change into it :
-```
+```bash
 mkdir build
 cd build
 ```
-Use the version of `cmake` that came with the SDK, and specify the location of its toolchain file as a cmake option. Also set the build target for OpenBLAS to ARMV8 and specify NOFORTRAN=1 (at least as of version 4.1.1, the SDK contains no Fortran compiler):
-```
-/opt/ohos-sdk/linux/native/build-tools/cmake/bin/cmake -DCMAKE_TOOLCHAIN_FILE=/opt/ohos-sdk/linux/native/build/cmake/ohos.toolchain.cmake \

-Additional other OpenBLAS build options like USE_OPENMP=1 or DYNAMIC_ARCH=1 will probably work too.
