How to build XNNPACK by Bazel 6.5
When I run bazel build :XNNPACK or bazel build //... I get:
xnnpack/MODULE.bazel:38:16: name 'use_repo_rule' is not defined ERROR: Error computing the main repository mapping: error executing MODULE.bazel file for <root>
When I run bazel build --config windows_x86_64 :XNNPACK
I get: ERROR: Config value 'windows_x86_64' is not defined in any .rc file
So, how do I build XNNPACK by using bazel? By CMake, it's all clear.
Thank you very much.
Hi, thanks for the question. As you referred to Windows, thats something I'm learning myself. From linux, I've used clangcl via lexan, which is --config=lexan_x86_64 and I've used wine or wine32 to test it.
But when building on Windows, as you say, cmake is easy. Although I mistakenly did it wrong, calling scripts/build-local.sh and it works anyway. But there is a .cmd script, which uses ninja but should be the same and gives an option for 32 bit x86.
I havent tried arm, but the 'local' approach works for me on riscv so i expect cmake on windows arm, for windows arm, would also work the same way.
For local builds using a default compiler
bazel build :all
That will be a 'fastbuild', and you can do optimized with
bazel build -c opt :all
So that should work on Window doing a local build for Windows, using Visual C. There are setup instructions that need to be done once to set up bazel.
For cross builds to other platforms, there is a config. e,g, --config=android_x86_64 Config names are being made more consistent, so its usually the OS and CPU, and hopefully the cpus have the same 'x86_64' naming going forward.
