# liblogoschat also statically links libchat's Rust bundle; linking librln

# statically too puts two copies of the Rust runtime in one image and collides
|
||
|
|
# at link time (`_rust_eh_personality`, `_ffi_c_string_free`). Consuming librln
|
||
|
|
# as a cdylib keeps its runtime in its own image — nothing collides and no
|
||
|
|
# symbol surgery is needed. We pull the prebuilt shared lib from zerokit's
|
||
|
|
# stateless release (the same asset build_rln.sh uses for the static archive)
|
||
|
|
# and give it an @rpath install name so liblogoschat.dylib loads it from beside
|
||
|
|
# itself at runtime.
