The problem arises from this bug in clang llvm/llvm-project#116278 which causes the following: ``` $ cc t.c -mpopcnt clang: error: unsupported option '-mpopcnt' for target 'arm64-apple-darwin24.4.0' $ cc t.c -mpopcnt -lpthread ``` The src/discover uses dune configurator, which always appends the C link flags from ocamlopt to the command line, and so the configurator erronously thinks that -mpopcnt will work. Since the dune configurator can't easily be overridden, this PR works around this specific link order issue by hand-calling the cc compiler from the discover binary. fixes janestreet#164 and janestreet#168 Signed-off-by: Yishuai Li <liyishuai.lys@alibaba-inc.com>

@liyishuai is there any particular reason you can't upgrade to v0.17.3 or later? |
