Please use Leap 15.0 (the latest Leap version) or openSUSE Tumbleweed, the rolling release, with latest software, including latest kernel. Tumbleweed ISO: http://download.opensuse.org/ports/aarch64/tumbleweed/iso/ or: Leap 15.0 ISO: http://download.opensuse.org/ports/aarch64/distribution/leap/15.0/iso/ > > When I attempt to engage the CRC and Crypto extensions the program > fails to compile.

If you use a recent version of openSUSE, GCC should provide the arm_acle.h file. I verified it on Tumbleweed, with GCC7 and GCC8.
