Checklist

[X] I've looked through the issues and pull requests for similar reports

Describe your issue

When building using cross, my binary size is significantly larger than when not.

cmd: cross build -r --target x86_64-pc-windows-gnu Run using docker in docker, my devcontainer using wsl on windows.

What target(s) are you cross-compiling for?

x86_64-pc-windows-gnu

Which operating system is the host (e.g computer cross is on) running?

[ ] macOS
[ ] Windows
[ ] Linux / BSD
[X] other OS (specify in description)

What architecture is the host?

[X] x86_64 / AMD64
[ ] arm32
[ ] arm64 (including Mac M1)

What container engine is cross using?

[X] docker
[ ] podman
[ ] other container engine (specify in description)

cross version

cross 0.2.5

Example

cross build -r --target x86_64-pc-windows-gnu My binary built natively on a windows machine is 8mb using cross its 23mb.

Additional information / notes

Probably the difference between x86_64-pc-windows-msvc and x86_64-pc-windows-gnu targets

Emilgardis commented 1 month ago

Comparing binary sizes for -gnu and -msvc doesnt really make sense, msvc has a lot of dynamic linking, it also bundles debuginfo in a .pdb file.

See https://doc.rust-lang.org/cargo/reference/profiles.html for tuning artifacts, and https://github.com/johnthagen/min-sized-rust for more tips
