[SPDK] Re: Failed to link spdk library

Hi,

crc32_iscsi comes from ISA-L for optimized CRC32 processing.  You have a couple of options here:

1) add the ISA-L library to your cmake environment - if you're using the SPDK build system, you should find it under spdk/isa-l/.libs/libisal.a
2) disable ISA-L by providing --without-isal to the SPDK configure script (and then re-build) - in this case, SPDK will default to a less-optimal implementation which may be fine depending on your use case

Regards,

-Jim
