error: aborting due to previous error
error: could not compile `futures-channel`
error: build failed

I have installed cargo and rustc through nix, and I have tried to check for the cc bin

❯ cc -v
clang version 7.1.0 (tags/RELEASE_710/final)
Target: x86_64-apple-darwin20.5.0
Thread model: posix
InstalledDir: /nix/store/rjy3p4j55ac4vyrmg18w2wrjgpfhsh4r-clang-7.1.0/bin

How can I fix this error?

This is still the first Google search result for "iconv cargo nix", so I'll post the solution I found here.

I am unsure whether or not this is intended or a bug in nixpkgs, but this error pops up because libiconv isn't included in the nix linker flags by default (you can check in $NIX_LDFLAGS). To include it, explicitly install it, e.g. via nix-shell:

#            ↓↓↓↓↓↓↓↓
nix-shell -p libiconv -p cargo -p rustc -p rust-analyzer -p rustfmt -p clippy
