Not Just ./a.out, but .dylib and .so Too — Separate Rust Builds

Setting prefer-dynamic = true in a Rust workspace enables dynamic-library linking for release builds. It is useful for optimizing build speed and binary size.

Workspace Cargo.toml​

Workspace​

[workspace]
# authors: KuuwangE <root@ql.gl>
# author repo https://github.com/shellcodesniper

resolver = "2"

members = [
  "entry",                          # NOTE: Entry point
]

default-members = [
  "entry",
]

[profile.dev]
prefer-dynamic = false # NOTE: Prefer dynamic linking
opt-level = 0
debug = true

[profile.release]
prefer-dynamic = true # NOTE: Prefer dynamic linking
opt-level = 3
debug = false
lto = true
# split-debuginfo = "unpacked"

Prevent "Could not found libstd-~~~.so"

ADD THIS to the binary module's Cargo.toml​

[dependencies]
prefer-dynamic = "0"

[dev-dependencies]
prefer-dynamic = { version = "0", features = ["link-test"] }

But... If the Error Still Occurs,​

Try this

MAC OS X​

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$PWD"
sudo ldconfig
./a.out

LINUX​

export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:$PWD"
./a.out
