Getting debuginfo

[RossSmyth]

Hello,

I'm new to Nix and am using it to cross-compile a project of mine to Windows. Part of my release process is to generate debuginfo so that I can look at release builds once deployed. I tried setting CARGO_BUILD_RUSTFLAGS = "-Cdebuginfo=2"; and while it seems to have compiled, the PDB file is not in the result folder.

How can I get the debuginfo file as part of the build artifacts?

Hi @RossSmyth ! Everything in crane is built on top of mkDerivation which strips debug info from all binaries by default. You might need to set something like dontStrip or separateDebugInfo to keep the data around. Hope that helps!

I tried setting separateDebugInfo and nothing changed. Stripping doesn't do anything on Windows binaries as debuginfo is always separate. I'll check upstream and see what's up.

Unfortunately I don't develop on Windows so I'm out of my depth here... Are you able to generate PDB files if you cross compile for windows without using Nix at all?

[RossSmyth]

You are right, mingw does not generate pdb files. I've always just build Windows binaries with MSVC so I did not expect that.
