-We recommend two different ways to build and install ACL:
-
-* Use the script located at
`docker/install/ubuntu_install_arm_compute_lib.sh`. You can use this
- script for building ACL from source natively or for cross-compiling the
library on an x86 machine.
- You may need to change the architecture of the device you wish to compile
for by altering the
- `target_arch` variable. Binaries will be built from source and installed to
the location denoted by
