Large executable while compiling for windows from Linux systems

[noelaugustin]

I have a simple Hello World program, which only has a single line in the main function of main.rs, which is
println!(Hello World);

Adding to the default package that is done by cargo init, the cargo.toml file has
[profile.dev]
panic="abort"

When I compile the code with target i686-pc-windows-gnu, with the linker being i686-w64-mingw32-g++ on linux, for windows, I get an exe, which is 3052 kB, and when i do the same with target i686-pc-windows-msvc, for windows on windows, I get an exe, which is 112 kB. Could someone suggest as to how I can reduce the size while I cross compile my code for windows from Linux? This is a concern as the difference in size is almost 30 times.

Those are separate targets (GNU vs. MSVC), what's the size when you build for the GNU target while on Windows?

Binaries linked by GCC are not stripped. Therefore this is duplicate of #46034

what's the size when you build for the GNU target while on Windows?

The same as when cross compiling from Linux.

Thanks, closing as a duplicate then.
