Project fails to build on M1 machines

[alecholmez]

I've gotten around the platform mapping issues by symlinking the envoy envoy/bazel directory into this project, but have encountered something that seems to look like macos options aren't propagating down:

(16:28:05) ERROR: /Users/alecholmes/Developer/greymatter-io/gm-proxy2/BUILD:12:16: Linking gm-proxy failed: (Aborted): cc_wrapper.sh failed: error executing command external/local_config_cc/cc_wrapper.sh @bazel-out/darwin_arm64-fastbuild/bin/gm-proxy-2.params

From what it seems is like options are being passed to a mac os specific linker that should only be on the linux side of things. I'm wondering if this is just the bazel setup.

My bazelrc looks like the following:

import %workspace%/envoy/.bazelrc

# overrides
build --copt=-Wno-unknown-warning-option

# current patch for building on M1 machines: 
# https://github.com/envoyproxy/envoy/pull/20889/files
build:macos --define wasm=disabled

# terminal ux
common --curses=yes
build --noprogress_in_terminal_title
build --show_task_finish
build --show_timestamps
build --worker_verbose

test --noprogress_in_terminal_title
test --noshow_loading_progress
test --show_task_finish
test --show_timestamps
test --worker_verbose

My LD and clang info:

$ which ld

I was able to fix this by not requiring exported_symbols=enabled --strip=sometimes bazel build args
