Older command line arguments failing in wasm-ld

[kushaldas]

While building CPython with wasi-sdk-21 I got the following error.

/opt/wasi-sdk/bin/wasm-ld   -z stack-size=524288 -Wl,--stack-first -Wl,--initial-memory=10485760   Modules/_testimportmultiple.o   -o Modules/_testimportmultiple.cpython-313d-wasm32-wasi.so
wasm-ld: error: unknown argument: -Wl,--stack-first
wasm-ld: error: unknown argument: -Wl,--initial-memory=10485760
make: *** [Makefile:3183: Modules/_testimportmultiple.cpython-313d-wasm32-wasi.so] Error 1

Can you please tell me what are the new/expected arguments to wasm-ld for this?

If you are invoking the linker directly you don't prefix the linker args with -Wl,. That prefix is what the compiler driver (clang) uses to distinguish linker argument.

This comes from CPython's configure.ac which sets it in LDFLAGS and has worked until now (e.g. WASI SDK 20 is fine with this). So we're trying to figure out who/what changed.

I found the issue on our side. We had not seen it before because dlopen() never existed before. 😅

Closing the issue.
