Subject: [PATCH 4/4] Disable whole-archive when linking rust
|
2022-06-09 17:57:34 +00:00
|
|
|
|
|
|
|
|
Rust .rlib archives contain an extra metadata file called lib.rmeta.
|
|
|
|
|
Emscripten sets `--whole-archive` by default if LINKABLE is set.
|
|
|
|
|
But with `--whole-archive` the linker crashes with an error due to
|
|
|
|
|
the extra files. This disables the problematic `--whole-archive`
|
|
|
|
|
setting when we are linking rust.
|
|
|
|
|
|
|
|
|
|
