Building error in ARM v8 system #388

Closed casm-ahb closed 1 month ago

casm-ahb commented 1 month ago

When I builded the libdeflate v1.21 on Kylin v4 with Feiteng CPU (ARM v8), errors were reported liking the following: ...... [35%] Building C object CMakeFiles/libdeflate_shared.dir/lib/adler32.c.o /tmp/cc6o7Zmc.s: Assembler messages: /tmp/cc6o7Zmc.s 423: error: unknown architectural extension 'dotprod' /tmp/cc6o7Zmc.s 494: error: unknown mnemonic 'udot' -- 'udot v27.4s,v19.16b,v23.16b' /tmp/cc6o7Zmc.s 495: error: unknown mnmeonic 'udot' -- 'udot v20.4s,v18.16b,v24.16b' ..... CMakeFiles/libdeflate_shared.dir/build.make:145: recipe for target 'CMakeFiles/libdeflate_shared.dir/lib/adler32.c.o' failed

How to slove the problem?

What operating system is this (e.g. Linux distro version), and what gcc and binutils versions are you using?

Can you check if https://github.com/ebiggers/libdeflate/pull/389 allows libdeflate to build on your system?

https://github.com/ebiggers/libdeflate/pull/389 should work around this, though it is better to upgrade your binutils to match your gcc version.
